Solving the Mystery of a Leaking House: How to Identify & Fix Water Leaks in Your Basement

Discovering a leaking house can be a disheartening experience. You can spend hours searching for the source of the leak only to come up empty-handed. Unfortunately, water leaks are a common problem in many homes, especially those with basements. Fortunately, there are steps you can take to identify and fix water leaks in your home. This blog will discuss the common causes of water leaks in homes, how to fix them, and how to prevent further leaks. Read on to learn more about how to solve the mystery of a leaking house.

What to Do When You Discover a Leaking House

If you discover that your house is leaking, the first thing to do is assess the damage. Take note of any visible signs of water damage, including water stains on the walls and ceilings, mould, and warped floors. If you suspect a water leak, locate the source of the leak as quickly as possible. This will help you determine the best way to address the problem.

The most important thing to remember is that water leaks can cause serious damage if left unchecked. It’s essential to act fast to avoid costly repairs down the line. If you’re concerned about the safety of your home, contact a professional to inspect the area and make the necessary repairs.

What Causes Water Leaks in Your House?

There are a variety of factors that can cause water leaks in your house. The most common culprit is ground water entering a home when it is buried underground and having nowhere else to go but inside your home.

In some cases, the source of the leak may be difficult to pinpoint. If this is the case, it’s best to call in a professional to help you identify the source of the leak. A professional can quickly pinpoint the source of the leak and make the necessary repairs.

Identifying the Source of the Leak

The first step in solving the mystery of a leaking house is to identify the source of the leak. This can be a tricky process, as the source of the leak may not be immediately apparent.

Start by looking for any visible signs of water damage, such as water stains on the walls or ceiling, mould, or warped floors. If you can’t find any obvious signs of a water leak, it’s time to start looking for more subtle signs.

Check for any unusual smells or sounds, such as a musty smell or gurgling noises. You may also want to check for any signs of moisture or dampness in the walls, floors, and ceilings. If you can’t find any visible signs of water damage, it’s time to call a professional. A professional will be able to pinpoint the source of the leak and make the necessary repairs.

Common Causes of Water Leaks in Basements

Basements are one of the most common areas for water leaks. This is because basements are usually the lowest point in the home, making them susceptible to flooding.

The most common cause of water leaks in basements is poor drainage. If your basement has no means of diverting ground water away from the home then it will enter the home instead. Water can easily seep in and cause damage.

Drainage Subsoil Solutions

If the source of the leak is poor drainage, you may want to consider installing a drainage subsoil system. A drainage subsoil system is designed to redirect water away from the house, preventing it from seeping in and causing water damage.

The drainage subsoil system consists of a network of pipes and trenches that are installed around the perimeter of the house. The pipes and trenches are designed to collect and divert water away from the house, preventing it from seeping in and causing damage.

This type of system is relatively lengthy and expensive to install but is the most effective way to prevent water damage long-term. If you’re concerned about the safety of your home, it’s best to call in a professional to install the system for you.

How to Prevent Future Leaks

Once you’ve fixed the source of the leak, it’s important to take steps to prevent future leaks. Whilst all the trenches are open around the home, the drain layers would seal up any obvious entry points to the home such as cracked bricks or holes in the walls. The drain layers also apply 2 coats of waterproof paint as a precaution to prevent any more water from entering the home.

DIY or Hire a Professional?

When it comes to fixing a leaking house, it’s important to decide whether you’ll do the repairs yourself or hire a professional. While it’s tempting to attempt DIY repairs, it’s usually best to call in a professional. This is because water leaks can cause serious damage if left unchecked. A professional will be able to quickly identify the source of the leak and make the necessary repairs.

If you want to get Drainage NZ to look at your house to see what can be done to stop the water form getting in, they offer a free consultation. During the consultation, they’ll inspect your home and provide you with a detailed report on the best way to address the problem.

Uncover Hidden Problems in Your Home with a CCTV Inspection!

It’s no secret that our homes are often the source of many of our biggest headaches. Whether it’s broken pipes, blocked drains, or simply an area of the house that needs a bit of TLC, we often find ourselves searching in the dark for a solution. But what if there was a way to quickly and accurately identify the issue and get it fixed? Well, that’s where a CCTV inspection comes in.

Introduction to CCTV Inspections
A CCTV inspection is the use of a closed-circuit television camera to inspect a home’s plumbing and drainage system. This type of inspection allows professionals to “see” inside the pipes and pinpoint any potential problems. It’s an invaluable tool for plumbing and drainage professionals and homeowners alike, as it allows for quick and accurate diagnosis of any issues.

The process is simple. A CCTV camera is inserted into the pipes and moved along the length of the pipe. As it moves, it takes pictures and videos of the interior of the pipe, allowing the technician to identify any potential problems. This information is then relayed back to the technician, who can then determine what needs to be done to fix the problem.

What Can a CCTV Inspection Reveal?
A CCTV inspection can reveal a multitude of problems. From broken pipes to blocked drains, a technician can pinpoint the exact problem and provide a solution. It can also help to identify any potential problems before they become an issue. This is especially helpful in older homes, where it can be difficult to identify any potential issues without a thorough inspection.

Some of the most common issues that a CCTV inspection can reveal include:

Blockages in the pipes
Leaks or breaks in the pipes
Root intrusion
Corrosion
Structural damage to the pipes
Cracks or holes in the pipes

How to Prepare for a CCTV Inspection
Preparing for a CCTV inspection is relatively easy. Before the technician comes to inspect the property, it’s important to ensure that all of the necessary access points are open and easily accessible. This includes manholes, cleanouts, and other access points.

It’s also important to make sure that the area around the pipes is clear, as this will help the technician to get a better view of the pipes. If there is any debris or obstructions in the way, it’s important to remove them before the technician arrives.

Finally, it’s a good idea to make sure that the pipes are clean. This can be done by flushing them out with water and running a snake through the pipes if needed. This will help to ensure that the technician can get a clear and unobstructed view of the pipes.

What to Look Out For During the Inspection
During the inspection, the technician will be looking for a variety of different things. They will be looking for any signs of damage or corrosion, as well as any blockages or root intrusions. They will also be looking for any signs of leaks, as these can be extremely dangerous and need to be fixed as soon as possible.

The technician will also be looking for any structural damage to the pipes. This can include cracks, holes, or breaks in the pipes. This is especially important in older homes, as these types of issues can often go unnoticed and can lead to serious problems down the line.

Common Problems Revealed by CCTV Inspections
The most common problems revealed by CCTV inspections are blockages, leaks, and root intrusions. Blockages are caused by a build-up of debris or other materials in the pipes, which can block the flow of water. Leaks can be caused by a variety of things, including broken pipes, corrosion, or even structural damage. Root intrusions are caused by tree roots growing into the pipes, which can cause blockages and damage the pipes.

How to Fix Common Problems Revealed by CCTV Inspections
After a CCTV inspection, the technician will be able to identify any problems and recommend the best course of action. In most cases, the technician will recommend one of two options: water blasting or unblocking.

Water blasting is a process where high-pressure water is used to flush out any blockages or debris from the pipes. This is usually the most effective option for blockages and is also relatively quick and easy.

Unblocking is a more involved process, where the technician uses specialized tools to remove the blockage from the pipes. This process is usually used for more serious blockages, such as root intrusions.

The Benefits of Using a CCTV Inspection
There are a number of benefits to using a CCTV inspection. First and foremost, it can help to identify any potential problems before they become an issue. This can save homeowners a lot of time, money, and stress.

A CCTV inspection can also save homeowners money in the long run. By identifying any issues before they become serious, homeowners can save money on repairs and avoid any costly problems down the line.

Finally, a CCTV inspection is a great way to help maintain the health of your home’s plumbing and drainage system. By identifying any potential problems and addressing them quickly, homeowners can help to ensure that their plumbing and drainage system stays in good condition for years to come.

Important Considerations When Choosing a CCTV Inspector
When choosing a CCTV inspector, it’s important to consider a few different factors. First and foremost, it’s important to make sure that the inspector is qualified and certified. This will ensure that the inspection is performed correctly and that any potential problems are identified and addressed quickly.

It’s also important to consider the cost of the inspection. CCTV inspections can be expensive, so it’s important to shop around and find the best deal. It’s also important to make sure that the inspector is experienced and knowledgeable, as this will ensure that the inspection is thorough and accurate.

Tips for Maintaining Your Home After a CCTV Inspection
Once the inspection is complete, it’s important to take steps to maintain your home’s plumbing and drainage system. This includes regular inspections of all access points, such as manholes and cleanouts. It’s also important to make sure that all pipes are clear of debris and that any minor repairs are addressed quickly. Finally, it’s important to make sure that all pipes are properly insulated to help prevent any issues in the future.

Conclusion
A CCTV inspection is an invaluable tool for homeowners and drainage professionals alike. It can help to quickly and accurately identify any potential problems and allow for quick and effective remedies.

What is a Cesspit NZ?

A cesspit or catchpit is a drainage system used primarily in stormwater management. Whether it is sewerage or stormwater, a cesspit is designed to prevent blockages and water contamination in a drainage system. A cesspit is a chamber that allows debris and sediments to settle to the bottom of a pit. For this reason it is advisable to regularly maintain your cesspit by emptying and cleaning at least once a year.

Why do you need a cesspit?

A cesspit is typically found upstream of a drainage system. This way the cesspit can collect all debris before it enters public or private stormwater pipes.

Cesspits are most commonly found in gardens, driveways or roadways. These environments typically collect large quantities of debris and sediment which if allowed through would cause blockages in a public drainage system. A blockage could cause flooding, water to return back up a pipe or worse damage property. Therefore a cesspit is vital when managing surface water in any of these environments.

By law all channels and subsoil drainage must flow into a cesspit to ensure no debris can flow into the private or public stormwater lines. For example, a driveway channel may be a vector for debris to collect, and so all water must be filtered before it can be discharged into the stormwater line.

How does a cesspit / catchpit work

Basically, a cesspit works by providing a sump where sediment and debris can fall and collect. Water overflows at the top level of the cesspit leaving debris behind at the bottom of the pit. The clean water then exits through the outlet pipe, which sits just lower than the inlet pipe.

To protect the outlet pipe against potential floating debris, a baffle can be fitted to the outlet. This can help filter leaves and twigs, stopping them from entering the pipe.

Because silt, sediment and debris build up in the sump of the cesspit, regular maintenance and cleaning of the cesspit is required. Typically the average cesspit should be cleared out annually to prevent a build up of debris. Such a build up could cause the cesspit to become ineffective, increasing the likelihood of damage from unmanageable water.

Types of cesspits

The most common form of catchpit is a roadside catchpit. Catchpits can be found intermittently alongside Auckland roads. What is unique about these types of catchpits is their design. Roadside cesspit openings must not allow objects greater than 100mm in dimension to pass through. Openings must also be small enough to prevent sizable debris from entering the system that may cause damage. These cesspits are typically larger than ones found on residential property. Under New Zealand building code these cesspits are known as a type 2 surface water sump.

A type 1 cesspit is no larger than an office paper bin. These cesspits are commonly used in residential applications such as in a driveway or garden.

There are many different names for a cesspit, such as:

  • Catchpit
  • Bubble up chamber
  • Receiving chambers
  • wet chambers
  • Dry chambers

Regardless of the name, the principles are the same. Incoming water is filtered to remove contaminants before entering a larger drainage system. This now clean water can then be confidently reused, recycled, or safely discharged into our oceans or environment.

Cesspits come in a variety of materials. The physical sump is typically made of:

  • Concrete
  • Polyethylene plastic

The top grate of a cesspit is typically made of iron. Iron grates are extremely durable and heavy. This prevents the grate from blowing away in strong weather.

With the increasing popularity of bicycle lanes, a newly designed cesspit finish is becoming more common. This new design is a flat stainless steel grate. Unlike the normal curved iron grate, this cesspit finish is designed to prevent accidents on bikes and scooters. More traditional curved grates can act like a pothole, dismounting commuters off their bike.

Maintenance

Because a cesspit is a static installation designed to filter stormwater it can quickly become full. If Debris and sediment pile up it will cause a blockage, damage and even flooding. Therefore it is necessary to regularly maintain cesspits by clearing excess waste. Ideally this should be done yearly.

Every homeowner should be concerned whether their cesspit is functional or not. One quick test you can do at home is to look down into your cesspit. If you cannot see an outlet pipe then it most likely means your cesspit is overflowing or blocked.

We at Drainage NZ offer our own regular maintenance service. Book with us and receive annual maintenance on your cesspit. We’ll turn up at the same time every year to empty and clean your cesspit with no fuss and at a competitive price.

Give us a call on 0800 372 465 or contact us online to organise maintenance on your cesspit.

Flooding: When council systems fail, what to do

When the drainage infrastructure fails it could spell disaster for your home or neighborhood. Council lines are not immune to failure, especially during a storm surge. When this happens it can cause flooding. Putting your home at risk of water damage. Even something minor like a boggy lawn can lead to problems in the future. Furthermore, If your home is older than 30 years old then this could put your home’s foundation at risk, causing structural faults.

Managing Flooding

So, flooding can be a serious issue for your property. Therefore having sufficient drainage solutions is key to prevent unexpected damages. Saving you a headache and thousands of dollars in the future.

If you notice parts of your property, such as your lawn collecting water this may be a sign of poor drainage. Subsoil drainage can help solve this issue. A pipe is placed underground and removes excess water to a nearby storm water sewer.

But what if the Council Lines Fail?

The drains and sewers built by the local council to serve as drainage for your area are only rated to a certain capacity. If there is a significant amount of rain such as during a storm then this could lead to flooding. Rivers could begin to spill out of their banks, and debris could clog the pipes. When this happens the council lines may not be able to remove the water fast enough.

If your area is prone to floods and you are concerned for your property what actions can you take to protect your home? Since subsoil drainage relies on the council storm water sewer then it is as good as useless in the event of flood. However there is a solution.

Underground detention tanks act as a buffer between your home’s subsoil drainage and the council lines. A detention tank stores water and discharges it into the council lines slowly to prevent over burdening the system. This also means that in the event of a storm, the tank can simply store the water until the drain can remove it.

If your property suffers from flooding or poor drainage give us a call at 0800 DRAINLAYER (372 465) or contact us online for a solution.

A Kiwis’s Guide to Preventing Mould Damage in Basements

Going down to the basement and finding that it’s filled with nasty moulds can be quite a nightmarish situation. Besides the fact that water damage is quite an eyesore, those rapidly growing microscopic organisms can trigger several health problems and structural concerns. Fortunately, there are ways you can prevent or mitigate mould damage in basements. Read through our short guide below and get expert insights on how you can handle the situation.

What are Moulds, and How can they Affect you?

Moulds can grow anywhere, even in well-maintained places. It’s a type of fungi, which means it propagates quickly in highly moist areas. The humid climate in New Zealand is also a major contributing factor of mould overgrowth.

They naturally occur outdoors, especially on dead trees and other types of debris. However, they can spread on various material such as wallpaper, wooden tiles, ceiling, and wooden supporting beams when they invade homes. If left undiscovered, mould overgrowth can cause severe structural damage as the materials rot and weaken. It also impacts your home’s aesthetic because of dark or sometimes greenish stains on the affected areas.

As we’ve mentioned earlier, moulds can also increase risks for many health problems, including:

  • Pneumonitis
  • Allergic sinusitis
  • Asthma attacks
  • Aspergillosis

How to Prevent Moulds from Growing, especially in the Basement

Most of the time, mould problem starts in the basement due to leaky pipes and other plumbing issues. That’s why it’s crucial to have your pipe problems fixed before they cause water damage. Some signs of pipe damage or leaks that you need to look out for include the following:

  • Unexplainably high water bill
  • Musty smell especially in rooms with a lot paper and wood
  • Visible stains caused by mildews or moulds
  • Wet and moist parts on the ceiling or walls

It’s also good practice to check for basement flooding. If your property was constructed back in the 1980s, it might be susceptible to basement flooding due to the absence of subsoil drainage. While it may be tempting to use stormwater sumps, it’s best to choose either waterproofing solutions or subsoil drainage installation to keep the water from coming in and accumulating in the area.

Here are other specific applications of subsoil drainage installation:

  • Properties with uneven landscape and high contour differences 
  • Auckland homes that have clay soil
  • Properties that require building retaining walls

If you already have subsoil drainage, you may opt to use basement flooding solutions instead. Talk to a drainlayer to know the most practical method to use to waterproof your home.

What to Do after Getting Rid of Extra Moisture in the Basement

Once you keep the moisture levels at an ideal rate, it will be easier to prevent or mitigate the damage. If you’re only dealing with minor damage, scrubbing with a powerful cleaning solution made from soap, bleach and water may be enough to clear out the mould and mildew.

However, if the damage is too severe and extensive, it’s better to call for a mould remediation professional. Dealing with severe mould overgrowth in your home is not recommended because it exposes you to health risks. Also, you might not address the problem as effectively as a mould removal or remediation specialist would.

Take note tht failing to remove or clean all the mould-infested areas would only spell trouble for your hour household in the next few months. The moulds can grow back and cause the same problem over and over until you completely address the root cause of it all.

Act Fast and Prevent Future Problems!

If you think your area is susceptible to mould damage and infestation, you need to act quickly. Have your drainage checked or ask for a professional house waterproofing to prevent moisture from seeping into the interiors. It’s also helpful to eliminate other moisture sources in the property such as washing machine or dishwasher leaks, poorly insulated windows or crawlspaces, and sewer backups. 

Get in touch with a drainage specialist or an Auckland drainlayer today to help protect your home from moulds.

Everything You Need to Know About Soakholes

In New Zealand a common method of managing rain water is Soak Holes. In the following information we will be focusing on the city of Auckland which is the most populated and quickest growing region in New Zealand.

In Auckland managing rain or so called “Stormwater” correctly is critical for the cities growth and infrastructure. Auckland Council is constantly challenged by the ever changing weather patterns and population growth. As the population grows so must the public stormwater system, the problem councils have is that the population is:

  1. Outgrowing the public stormwater system
  2. The public Stormwater system can’t grow quick enough to keep up with the demand. This is a costly task that only can only be done during certain times of the year and only as it’s needed. As such, councils are always behind on growing the city’s public infrastructure.

Several years ago, council engineers came up with a quick fix that would help slow down the effects of population growth and the introduction of more water being collected from new roofs that would discharge into the public system.

Design regulations for new builds and subdivisions now included the requirement and/or option to;

  • Allow a property to manage its own stormwater as much as much possibly practical by means of retention tanks, detention tanks (regulated overflow allowing the public system to keep up when there is a high demand) and soak holes.

In section, we will be focusing on the different types of soak holes and how they can help property owners manage rain water from roofs and surfaces successfully. 

Three Different Types of Soak Holes in Auckland

Residential Soak holes

In the early days many areas around Auckland did not have a public storm water system to connect onto. If you had a public connection, you were considered very lucky! Year later in 2020, some areas still don’t offer public a infrastructure. Many homes, especially those built in the 60’s and 70’s continue to manage their roof and surface water within the boundary. This is typically done by means of an onsite ‘Soakhole”.

As drainlayers when we ask for a LIM to identify what

Onehunga Soakholes

Its all about ground percolation and enabling a site or home to manage its own roof and/or surface water within the site itself. What better way is there than allowing nature to do its own thing?   The concept of the Onehunga soakhole does exactly that. (Speak to Drainage NZ about Soakhole drilling, engineering and design.

A GEOTECH drilling rig is arrange to drill down into the volcanic bedrock where a pipe riser is inserted to enable water to overflow as far down as applicable design stipulates. At that point, water will disburse naturally underground. Geotechnical drilling services are available)

As you can see in the design below, the soakhole does have a safety mechanism in case the drilled bedrock hole blocks or should the incoming water exceed the soakhole capacity. This is the overflow point shown as the entry head.

At this point water may overflow into the public system or external soakage trench as shown below.

Trench Field Soakholes

When rock is not available the GEOtechnical engineer may explore the option to discharge stormwater into a scoria layer underground if the site is suitable. The principal is simple. If found scoria layers can act as a disbursement field by allowing water to travel downstream across a whole suburb below the ground, naturally finding a route to the ocean. Because percolation is limited.

For more detailed information about soakholes and soakhole regulation, please download the following guide called Auckland Soakhole Design Manual.

The purpose of this Manual is to provide guidance in the design of stormwater soakage devices for residential and commercial properties in soakage areas of Auckland  City.    Soakage  areas  have  limited  stormwater  reticulation,  and  are  primarily located in parts of Ellerslie, Penrose, Onehunga, Mt Eden, Epsom, Mt Roskill  and  Mt  Albert.    Public  soakage  devices  are  provided  for  runoff  from  roadways  in  these  areas,  but  individual  property  owners  must  construct  and  maintain  their  own  soakage  devices  for  runoff  from  private  properties.    The  soakage  devices  allow  stormwater  to  percolate  into  the  ground,  and  generally  consist of either boreholes into fractured rock or large holes filled with scoria.  

Can I make my own Soakhole?

The building code does allow a certain extent of “Garden Drainage” without involving a specialist, designer or even a registered drainlayer. We highly recommend you familiarise yourself with the rules before you attempt a DIY. Getting wrong could cause severe your or others property.

The quick answer to the question above is no. Soakhole need to be designed based on a series of things, including:

  1. Location (certain criteria needs to be met)
  2. Incoming water capacity
  3. Geotech conditions
  4. Size and depth
  5. Environmental effects.

The law is a more flexible around existing soakholes that need repair or redrilling. A repair may bypass all the consent and engineering requirements.

If you need your soakhole repaired, moved or removed please speak to our drainage engineers that will be able to help you find a solution that suits your budget and site. 

 

Not only should clients be aware of what the engineering notes are but so should the contractor to ensure a realistic scope is covered which will allow the client to budget the project accordingly.

Watercare Asset CCTV Pre and Post Inspections

Working on a property development or construction project sometimes entails installation, modification and extension of public drainage systems. As a result, you may be required to apply for a Works Over approval.  Typically, before proceeding with the project an engineer or Watercare representative will get involved to ensure compliance is met and to ensure that the process won’t put the Watercare assets at risk of getting damaged.  

As a drainlayer, we help you ensure that the condition of any public sewer system is investigated before or after any work takes place. The inspection procedure is carried out with CCTV equipment and still images.

Watercare Asset CCTV Inspection

Before Watercare Asset CCTV Pre and Post Inspections became popular, plumbers had to do open-cut excavations. While sewer excavations can deliver results, it can be a very intrusive process. It also consumes a lot of time and costs a lot of money. Unless you are 100 percent sure that the pipe damage is severe, you don’t need to opt for a sewer excavation service. 

A CCTV drainage survey is more than enough to help you find the root cause of your drain pipe problems in a residential or commercial property. It’s also the fastest, most practical and cost-effective way to inspect Watercare assets. 

How does CCTV Pipes Inspection work?

The process involves inserting a sophisticated camera to inspect the pipes. For larger pipes, like those used in sewerage systems, a CCTV tractor is used. For smaller ones, such as those used in Watercare assets, plumbers utilise a snake profile camera. 

As the plumber pushes in the camera inside the pipes, you get to check for possible problems such as clogs, cracks and leaks. You can either have the option to check the video feed in real-time or review it after the service with the DVD provided by the plumbing company. 

Typically, the video contains overlaid text containing details like the pipe name, street address, pipe diameter, pipe shape, date and time of CCTV inspection and depth of the access points. 

After the survey is done, the plumber will discuss the findings. Below are some of the key things that you can check via a CCTV pipe inspection:

  • Hairline cracks that affect the integrity and stability of the pipes
  • Bigger cracks that can affect water pressure and bring in sand and silt inside the pipes
  • Tree roots and other organic debris stuck inside the pipes
  • Punctures on the pipe due to previous renovation work
  • Corroded or severely damaged pipes and assembly joints
  • Location of other pipe joints and how to access them
  • Pests such as cockroaches and rats that poses risk for pipe damage and health issues

Timely or regular inspection of drain pipes through CCTV surveying can help you save a lot of money on repairs or other services. It can also help you find out what plumbing issues you need to address before proceeding with a construction, development, or renovation project. If in case the sewerage pipes in the property need work because of material buildup, you can avail a combo package which includes CCTV pre and post-inspection service and drain unblocking.

Beyond Pipe Repairs and Damage Mitigation

Besides coming handy in finding plumbing issues to fix in a property you already own, a CCTV drain survey can also be useful in other scenarios. For example, before you purchase a new property, you can have the pipes inspected to check for pipe problems. 

It will help you determine whether it makes sense to invest money in a certain property. Knowing potential or existing drain pipe issues would also allow you to renegotiate the price so you can make room for your renovation expenses.

A typical CCTV survey would only cost you hundreds of dollars per hour. It’s a good investment whether you’re a property owner or a property developer.  

The Drain Pipes are Damaged or Clogged, What’s Next?

If the CCTV survey indeed reveals that your pipes are damaged or clogged, your next priority is to plan your next step. You can figure out the approach to use, depending on the severity of the problem. For example, if the results show hairline cracks, you might need to have the pipes repaired to prevent further damage. If the pipe problem arises from material build-up then the plumber can use a different approach like hydro blasting.
