How To Find A Plumbing Leak In Your Home

Though they can be relatively minor, plumbing leaks are one problem that mustn’t be forgotten about. Why? Not only do they cause water to be wasted, but they can also cause a major plumbing disaster down the line, and we know that coming home to a flood is probably not on your list of things to do! That being said, we wanted to dedicate this Water Wednesday to educating our readers on how to find a leak in the home so that they don’t go unnoticed for too long; check out our tips below:

First things first – always pay close attention to the areas surrounding your water based appliances. For example, whenever you visit the bathroom, make note of what the floor near the sink looks like. By being proactive and checking in on areas like this often, you can begin to notice leaks earlier on.

Now how to locate it

If you know there is a leak in your kitchen, bathroom, wall – wherever it may be – but can’t seem to find the source, do the following:


Start by checking the space under your sink for any sign of moisture. But, if the leak isn’t coming from your sink’s pipes, you’ll need to move on to the shower. To locate the source of a leak near the tub or shower, start by splashing some water around the shower door to see if any spills out onto the floor. Additionally, you should also inspect the caulking around your fixtures to see if there are any cracks. If some are present, there is a good chance your leak is stemming from them.


Similar to your bathroom, your first plan of action should be to check under the sink. If the bottom of the P trap is moist or you notice water stains on the bottom of your cabinets, you can bet that the the leak is starting in your sink. Additionally, if you notice a change in behavior in your floor, such as laminate becoming loose, you may be able to track the leak back to your sink too.


Noticing a leak in your wall is pretty easy – those dark stains are hard to miss! In this scenario, though, it’s finding the source that can be tricky. As soon as you notice any sign of a drip, see if you can trace where it starts and ends. At this point, you should at least be able to determine where the leak is based. Then, an expert plumber like ourselves can come in and do the rest!
