How to Find a Water Leak in Your Wall

May 04, 2020

Are you concerned you might have a leak somewhere? Follow this guide to help identify the cause! Then pick up the phone and call us when you're ready to get it fixed.

How to Find a Water Leak in Your Wall

There are a few ways you can check if you have a water leak inside your wall. Some methods are more obvious than others, yet some should only be done by an experienced plumber. We’ll go over a few ways you can check here.


Wet Spots in Carpet


If you have any areas of your carpet that are always wet, then chances are you have a leak. You may find these leaks near places such as near appliances like washer, dishwasher, and by other areas such as near sinks, toilets, and bathtubs/showers.


Higher Water Bills


You may notice your water bill is higher than it should. While water use generally fluctuates, if your usage spikes to a level that doesn’t make sense, then there’s a good chance you have a leak somewhere.


Damaged or Discolored Walls


If you have any walls that have visible damage, a change in texture, or the color has changed in places where it shouldn’t, then that is a sign of a water leak. This will be irregular in appearance and not consistent with the rest of the wall.


Mold or Mildew


If you’re dealing with mold in places, chances are a leaky pipe caused it. Mold is a serious health concern and even though mold can be removed, it will return if the root cause is not identified and corrected.


The Nose Knows!


Even if you don’t see anything, your nose may be the only way to discover a problem! If you’ve noticed any areas of your home that smell musty. Be aware that this is usually accompanied by damage to the texture of the wall, but not always! In fact, thick drywall can act as a sponge, and hide the water damage.


Your Ear Can Hear!


Barring other signs of water damage, you may notice a dripping noise somewhere. This is another sign of a leak. In the first few seconds after turning off your shower, sink, or flushing the toilet, listen for any dripping noises coming from the walls. If your pipes are made of PVC, you’ll have a better chance of hearing it as they amplify the sound. If they are not PVC, you may have a harder time finding the source.


Check Your Meter


To discover if it is defective plumbing causing the leak, turn off everything that uses water such as sinks, toilets, and any appliances. Check the water meter, write it down, then check it again in 3 hours. If the number went up, then you have a leak somewhere. If it didn’t increase, and you still have a leak, then the source is either from your roof or it’s entering somewhere else through a wall.

Once you’ve found the leak, you’ll definitely want to get it fixed as soon as possible to prevent further damage to your home. The experts at Plumbing Houston are ready to take care of you even in emergencies, so don’t hesitate to call us to solve your leaking problems!
