Leaking Bathtub: How to Find the Source

Having a leaking bathtub is more than just annoying, it’s wasteful and can be expensive.

But how can you find the leak in your bathtub?

Today we’ll walk you through a few steps you can do to determine if it’s an easy fix you can do yourself, or if you’ll need the help of a plumber to stop the leak.

In order to figure out where the leak is coming from, you’ll need to do a few amateur “diagnostic tests,” if you will.

There are a few different places the tub might leak, like:

  • The faucet
  • The grout (around the sides of the tub)
  • The drain
  • The pipes

While some of these have simple fixes (for instance, if your drain is leaking, you can get a temporary fix for it by buying a drain plug that can hold off the water a little more securely), but some of them - like a serious leak in the grout or the pipes - will require a licensed plumber to fix.

Here’s how to figure out which part of your tub is leaking:

First, ensure the exterior of the bathtub is completely dry.

Then lay down newspaper, paper towels, or towels around the base of the tub.

Plug the drain, and start to fill up the tub.

Watch the newspaper carefully to see if any of it gets wet, and if so, where.

If the tub fills up and the exterior of the tub stays dry, then the leak isn’t in the grout, and the good news is the exterior of your tub is fine!

With the room quiet, listen carefully. Do you hear water slipping through the drain?

It’s possible that the drain wasn’t installed correctly, or as it ages, needs attention.

If the drain seems well-sealed and the grout is fine, then the leak is more than likely coming from the pipes themselves, underneath the bathtub.

That may be a simple fix, but it’s going to require a licensed plumber to inspect and diagnose the problem.

Does a Tiny Leak Really Matter?

As a homeowner, it’s important to keep in mind that a pipe leaking under your bathtub may or may not be a big deal; but if one pipe is leaking, it’s often a sign that others are, too.

Since your water lines are probably all the same age, if you notice a weakness in one pipe, it’s very likely in others, too. And some of those pipes, if they were to start leaking, could cause serious damage to your home.

It’s always better to ward off the damage before it begins, don’t you think? Make the BEST choice and call BEST Plumbing Service of Cincinnati to get a licensed plumber out to your home to inspect your plumbing system today.
