How To Fix Drain Pipe Leaking Into The Wall Or Under The House

Leaky drain pipes can create a slew of issues. Here's a step-by-step approach to repairing a leaking drain pipe in your home.

Are you looking at solutions to fix a leaking drain pipe under a house? If this is the case, the first step is to determine the material of the pipe and the location of the leak.

Leaking drain pipes in the wall or under a house are subtle little hazards in the home that generally go undiscovered. Sadly, no matter how moderate they are, they could result in greater problems in the foreseeable future. Leaking pipelines not only wastes water but also fosters undesired bacterial buildup and can cause building damage as well as power lines.

Big signs leaking drain pipe

If your drainage system appears to be in clear operating condition, there may be an underlying area of concern. This includes your sewer system. However, there are strong indications that you should contact a plumbing company before it becomes too severe.

Now let us explore ways to discover a leaking drain pipe in your household.

Sewer Odor

Sewage system pipelines are designed to be resilient, so smelling sewer odor is a critical challenge because you should never be lucky enough to catch a breath of fresh air from it. This sewer odor would be considered an alarming situation for identifying a leaking drain pipe.

Mold Growth

Spontaneous humidity from a leaking drain pipe is a primary contributor to mold growth indoors. Furthermore, because of the nature of its usage, a wash basin drainage is present in a high-humidity location. As a result, you should not be shocked to observe mold growing in this location.

Wall Damage

Inappropriate pipe installation could cause major wall damage due to excess water leaks from drainage pipes. Defective or leaking drainage pipes generate dampness in the walls, destroying the paint and disrupting the clean sheen.


Clutter tends to make portions of the household unreachable and incredibly difficult to wipe down, and pests and mosquitoes seeking refuge could well be drawn to the clutter, leading to infestation.

What causes a drain pipe to leak into the wall or under the house?

Leakage would not pollute the water but also cause building damage. It also promotes undesirable bacteria development within the sewage system. Regrettably, most of the piping system in your home is hidden, you will not always notice a blockage.

Understanding and looking for what causes a drain pipe to leak in the wall or under the house is one of the easiest ways to prevent your home from future leakages. The following are some of the most common causes:

Loose Compression Nut

This compression nut can create a watertight link between two pipes. When this nut comes loose, you are likely to experience a small or large leaking drain pipe, depending on the water flow level. Surprisingly, it is one of the simplest ways to fix and repair drain pipes that can be completed in a matter of minutes.

Worn Compression Nut

This compression occurs only if your sink is getting old and needs to be replaced. This leak will not be stopped unless you replace your sink. If this is the case, you should not be concerned because the repair is both inexpensive and quick. Contact the experienced plumbers at Drain Express for prompt sink replacement service.

Ill-Fitted Pipes

Have you recently moved to a new apartment where you equipped a sink in your kitchen and therefore are undergoing water leakage? If this is the case, there is a chance that the pipe dimensions do not correspond to your desired fitted sink. Ill-fitting drain pipes generate pressure, which can lead to leakage of water if not addressed. It is recommended that you request a professional plumber to properly assess the installation configuration of your sink.

Pipes need to be replaced

Drain pipes that are decayed, broken, erupt, or starting to leak should be replaced as quickly as possible. Not only are you exposing your home to water damage, but a broken drain pipe may also permit sewer gases to accumulate in your bathroom and kitchen.

Water Pressure

The water pressure in your home may be too high for your sink, causing leaking even if there is hardly anything wrong with the pipelines or sealants. Even if you don’t think your water pressure is too high, it can cause a variety of issues. Water pressure in a house should be between 40 and 45 psi, although a few compression regulators are placed at 50.

DIY tips to stop and patch leaking drain pipes

Do you know that leaving your water drain pipes unrepaired can cause damage to the building you live in? If not, let’s go over how to stop leaking drain pipes in greater detail. There are numerous solutions available, but you always choose the simplest and most immediate. You can use epoxy putty and pipe clamps to seal the leak in your pipe.

Keep in mind that this is only a temporary fix for a leaking pipe. Remember to turn off the water supply while working on fixation to achieve a perfect result.

Why it’s better to work with a professional leaking drain pipe specialist?

Every householder confronts plumbing emergencies, and it is enticing to find a way to solve each issue on your own. However, not all plumbing issues are easily resolved. Attempting to repair them may result in additional costs and delays because you may aggravate the situation.

So, if you have plumbing issues, it is preferable to find a professional plumber instead of performing your repair services and fixtures. Still, have reservations? Drain Express offers experienced plumbers to make your drain leaking system seamless.
