5 Common Plumbing Leaks Found In & Around The Home: A Comprehensive Guide

Dealing with a plumbing leak can be frustrating because it means something needs to be repaired or replaced (and usually there’s damage that needs to be addressed as well).

In order to prevent leaks from occurring, or minimize the damage when they do happen, you should know the most common leaks you might experience.

What You Should Know About Common Plumbing Leaks

Here’s what you need to know:

1) Pinhole Leaks

For those of you with copper pipes in your home, corrosion can begin to take its toll on your plumbing after years and years of use.

When a copper pipe corrodes enough, a pinhole leak can form at the weakest point of the corroded pipe. Pinhole leaks can be easily discovered and fixed as long as you inspect your plumbing regularly.

To fix a pinhole leak, simply apply a small piece of activated plumber’s putty over the hole. This should stop the leak. While this may stop the leaking, for now, this should be a temporary fix. Highly corroded pipes should be replaced to prevent future leaks.

2) Shower Splash Leaks

The most common leak you’ll see in any bathroom is when water escapes your shower and splashes onto the floor. Yes, this is still considered a leak — and it can cause major damage!

Water can easily “leak” out of your shower by a shower curtain that isn’t closed all the way or a faulty shower door. To keep water from escaping the shower, ensure your shower curtain is fully closed, have the inner shower door closest to the shower head, and check for any faulty gaskets or gaps that need to be replaced or filled with waterproof caulk.

As water splashes onto the floor, it can soak into the space where the shower/bathtub meets the floor. Eventually, this water can begin to loosen the shower/bathtub from the vinyl flooring, cause mold growth, and even reach the wood that makes up the floor.

Years of ignoring this can lead to you needing an eventual full tearout of the affected area from excessive water damage and mold beneath the floor.

3) Under Sink Supply Leaks

When you go to grab something from the cabinet that’s underneath the sink, you’re usually in and out without much looking around. Next time you go to grab something from under the sink, take a look around — there could be a leak you never knew you had!

The water supply lines and the sink trap are both pieces of plumbing that experience leaks. While the sink trap will only leak when water goes down the drain, the supply lines in the back of the cabinet can continuously leak as there’s always water present here.

When you discover a leak, first check to see if you can tighten any fittings or realign any connections. If this does not stop the leak, there may be pieces you need to replace entirely. Contact your local plumber to limit the amount of damage this leak is causing your bathroom or kitchen.

Chances are this leak has existed for quite some time now and there’s a good chance water damage and mold already exists that also needs to be remedied...

4) Toilet Flange Leaks

Yes, toilet leaks can occur in the tank which causes the water to constantly run. While these leaks are bad for your wallet, a toilet flange leak is one that can cause a serious amount of damage.

The toilet flange is a piece that helps connect your toilet to the waste pipe at the base of the fixture. When the toilet flange is not installed properly or needs replacement, water can leak from the base of the toilet. You’ll know you have a toilet flange problem when you see water leaking from the base of the toilet or if the toilet moves while you’re sitting on it.

In order to fix a malfunctioning toilet flange, you’re going to need to drain and remove the toilet. Once removed,install a new toilet flange and wax ring. However, you may need to repair the flooring underneath if this leak caused extensive water damage. A professional plumber should inspect the floor underneath to let you know of its current condition.

5) Main Sewer Line Leaks

The worst leak you can have in your home (other than a burst pipe) is a leak in the main sewer line. The reason this leak is one of the worst to have is that it is the main piece of plumbing in your home that connects to every fixture (and appliance) and directs waste water away from your home. To make things worse, it’s also underground…

Leaks in the main sewer line can be caused by corroded piping, tree root infiltration, excessive blockages, movement in the ground soil, and many other reasons. This is the type of leak you want to know about ASAP to limit the amount of damage done to the sewer line.

When you notice multiple plumbing fixtures backing up frequently, a sunken and soggy lawn, or water coming out of drains when other plumbing fixtures are in use — then you should have your main sewer line inspected by your local plumber.

A leak can spring at a moment’s notice and it’s up to you to know where these leaks can occur and what to do about them.
