Signs Of Hidden Sewer Pipe Leaks In Your Yard

Maintaining your yard can be a daunting task, especially when faced with sewer pipe leaks. Although it’s essential to keep your yard in a well-manicured condition, it’s just as crucial to pay close attention to detail when it comes to signs of hidden sewer pipe leaks.

The longer the leak goes unnoticed, the more likely it could result in health hazards, unpleasant odors, and costly repairs. Below, we provide you with some of the essential signs to look for that may indicate hidden sewer pipe leaks in your yard.

Unpleasant Odors

Our sense of smell can be an excellent indicator of problems in our yard. A sewer pipe leak can produce a noxious smell, which can make it challenging to enjoy the outdoor activities. Look out for the following smell to determine a leak in your sewer pipe:

  • Foul smell: This is a sign of rotting sewage and should be taken seriously.

Soggy Spots In The Yard

Yard playing host to many visitors should be preserved and adequately maintained. However, when you notice that certain spots in your garden are significantly soggier than others, it could be an indicator of sewer pipe leaks. Look out for the following signs:

  • Unusual puddles in the yard
  • Soft and damp ground where people walk
  • Sinkholes appearing
  • The sudden increase of grass growth in certain areas of the yard

Slow Drainage

Slow drainage can be a clear pointer to hidden sewer pipe leaks. When drainage is slow, it means that water isn’t flowing as it should. Instead, water is collecting somewhere that shouldn’t be. This often starts with the following, which indicates slow drainage:

  • Shower or bathtub drains more slowly than usual
  • Sink takes more time than usual to drain.
  • Toilet takes much more time than usual to flush.

Increased Water Bills

Undetected leaks can result in cutting deeper into your wallet than you might expect. If your water bills seem mysteriously high, it’s time to start looking for signs of hidden sewer pipe leaks. Water-bill cuts across different parts of the house, and it takes a keen eye to determine where exactly the leak is coming from and whether it’s a sewer pipe leak.

  • Compare monthly water bills: Month-on-month increase in water bills could indicate a problem.
  • Unusually high water bills: This likely indicates an active leak in the main water line or sewer pipe.

Finally, proper plumbing maintenance comes with adequately taking care of our environment. With these signs listed above, homeowners can keep an eye out for potential sewer pipe leaks and ensure their yard remains a serene and safe place.

Locating Hidden Sewer Pipe Leaks In Your Yard

Shutting Off Water Supply

If you suspect a leak in your sewer pipe, you must shut off the water supply immediately. To do this, locate the main water shut-off valve, which is typically located near the water meter. Once you have found it, turn the valve in a clockwise direction until it stops.

This essential step will prevent any further water from flowing into your pipes, allowing you to detect the location of the leak.

Inspect Your Yard

After shutting off the water supply, now is the time to inspect your yard for any signs of a leak in your sewer pipe. Here’s how you can do it:

  • Look for areas of standing water or excessively damp grass.
  • Notice any sinkholes or any sudden dips in your yard.
  • Pay attention to any odors of sewage, which might indicate the location of the leak.
  • Observe any unusual patches of grass or vegetation that may have grown faster than other parts of the yard.

Inspect Indoor Plumbing Fixtures

While inspecting your yard, it’s also essential to inspect your indoor plumbing fixtures. This step will help identify where the leak might be originating from. Here are a few things to consider:

  • Check for slow drains or backups.
  • Look for any water damage or wet spots on the ceiling or walls.
  • Inspect visible pipes for any signs of corrosion or leaks.

Using A Plumbing Camera

If your initial inspection does not reveal the location of the leak, you must seek a professional plumber’s assistance. A plumbing camera can help detect leaks that are hidden from plain sight. The process involves a plumber inserting a small camera into your sewer pipe, relaying real-time images of the pipes’ interior to identify the damage’s location.

Locating a hidden sewer pipe leak requires careful inspection and attention to detail. Always shut off the water supply first before looking for any signs of a leak in your yard or indoor plumbing fixtures. If all else fails, contact a professional plumber to use a plumbing camera to locate the damage.

Remember, the sooner you identify and repair the leak, the less damage it will cause to your property.

Visual Inspection

The first step in detecting a sewer pipe leak is through a visual inspection. Here’s what you need to do:

  • Look for signs of water pooling in your yard.
  • Check for any unusual odours. Sewer gas smells like rotten eggs.
  • Look for any depressions or sinkholes in your yard. They indicate soil erosion caused by underground leaks.
  • Inspect your lawn for unusually green and lush areas. They indicate a sewage leak underground.

Once you have identified any of the above signs, you can move ahead to the next steps.

Conducting A Dye Test

A dye test is a reliable method to check for sewer pipe leaks. Here’s how to conduct it:

  • Turn off the main water supply to your house.
  • Identify the cleanout pipe in your yard and remove its cap.
  • Choose a brightly coloured, water-soluble dye and flush it down the toilet.
  • Wait for 30 minutes and then check the cleanout pipe. If the water in it is coloured, it indicates that a leak is present in your sewer pipe.

Conducting A Pressure Test

A pressure test is another way to determine a leak. Here’s how to conduct it:

  • Turn off the main water supply to your house.
  • Connect a pressure gauge to an outside faucet that’s close to the main water shutoff valve.
  • Close all other faucets inside and outside the house.
  • Read the pressure gauge. It should read between 40 and 80 psi.
  • Leave the gauge on for a few hours and then re-check it. If the pressure has dropped, it indicates that there’s a leak in the pipe.

By following these DIY methods, you can easily detect hidden sewer pipe leaks in your yard and prevent further damages. Remember, early detection is crucial to avoid costly repairs and potential health hazards.

Professional Techniques To Detect Hidden Sewer Pipe Leaks In Your Yard

Sewer pipe leaks can be a nightmare to deal with, especially when they occur in your yard. They can lead to soggy soil, foul odors, and even damage to your home’s structure. Therefore, it’s essential to detect them efficiently and quickly.

Here are some professional techniques to determine hidden sewer pipe leaks in your yard:

Smoke Testing

This method involves blowing smoke into the sewer pipes to locate the leak. The smoke travels through the pipes and eventually escapes through the leak, indicating its location. Here’s how this technique works:

  • The sewer pipes are closed off at the property line and roof vent using inflatable devices.
  • Smoke is blown through the pipes to fill them up.
  • Once there is enough pressure, smoke flows to the leak, enabling workers to identify its location.

Thermal Imaging

Another efficient method of detecting hidden sewer pipe leaks is thermal imaging. This method uses infrared cameras to identify temperature differences in the soil above the sewer pipes. Here’s how it works:

  • The sewer pipes are disconnected from the house and flushed out.
  • The soil above the pipes is scanned using thermal imaging.
  • Temperature changes in the soil above the pipes reveal the location of the sewer pipe leak.

Ground-Penetrating Radar

Ground-penetrating radar is an effective method for identifying leaks in sewer pipes installed underground. It uses radar waves to capture images of the subsurface. Here’s how it works:

  • Ground-penetrating radar is used to capture images of the subsurface under the suspected leak area.
  • The images are analyzed to identify any underground sewer pipes.
  • Any damages or leaks to the pipes are identified using the images.

These professional techniques for detecting hidden sewer pipe leaks can save you time, money, and prevent further damages to your property. If you suspect a leak, contact a professional to diagnose and resolve the issue.

Repair Options For Hidden Sewer Pipe Leaks In Your Yard

Excavation And Replacement

The traditional method of fixing hidden sewer pipe leaks is by excavating the area and replacing the damaged pipe with a new one. This method involves digging up the affected area, locating the damaged pipe, and cutting it out. The new pipe is then installed in the same location, and the area is filled back up once the repair is complete.


  • The new pipe is guaranteed to be durable and long-lasting.
  • This method allows for a thorough inspection of the sewer line to identify any other potential issues.


  • It is labor-intensive and expensive because of the excavation process and material replacement.
  • It can take some time to complete.

Pipe Relining

Pipe relining is an alternative to excavation and replacement, commonly known as the “no-dig” solution. A new lining is inserted inside the old pipe, covering any cracks and creating a new, smooth surface that can last up to 50 years.


  • It is less invasive than excavation and replacement.
  • It’s eco-friendly since it reduces the need to dig and hence minimizes the destruction of flora and fauna.


  • It may not always work if the pipe is severely damaged.
  • It can be difficult to isolate and repair the issue if the lining itself becomes damaged.

Determining the most appropriate method involves the consideration of some factors such as pipe age, damage, and budget. Therefore, if you have leaking pipes, it is essential to contact a professional plumber to discuss repair options that are best suited to your situation.
