Fixing a Leaking Tub Spout: Cost and Solutions

Fixing Leaking Tub SpoutYou may have encountered this issue before. You go to turn on your tub faucet, and water starts to leak out the back. This usually indicates that you have a leaky tub spout from a worn washer or plumber’s putty.

A leaking tub spout is a common plumbing problem that can be frustrating, but it’s not difficult to fix. The question is: How much does it cost to fix a leaking tub spout?

The answer depends on where the leak is and how advanced it is. If you have a new faucet or shower head, you might be able to repair it yourself. If not, call a plumber for help.

Reasons why Tub Spout is Leaking From The Back

Improper Installation

If you had someone else install your tub spout, it might not be installed correctly. This could cause leaks in two different ways:

The pipe connector was not inserted into the correct hole. A typical installation requires two pipes (one for hot water and one for cold water) to be connected to each other with a screwdriver or wrench. The pipes should not be tightened too much because they can crack, which would cause leakage. In addition, over-tightening can cause water pressure problems or even damage pipes, which would eventually lead to leaks at some point.

The pipe connector was not inserted into the correct hole and did not tighten properly. If this happens, water may leak out of the pipe connection instead of going through the shower head or faucet spout itself.

Fixing Leaking Tub Spout


Another reason why a tub spout may be leaking from the back is corrosion. If you have an older home with galvanized pipes, there’s a chance that they’re starting to corrode and leak. This can happen over time if you don’t regularly maintain your pipes by flushing them with vinegar or baking soda and water solutions. A quick fix for this problem is installing new copper pipes in place of galvanized ones.

Faulty Valve Assembly

If your tub spout is leaking at its base and there’s no evidence of improper installation, then it could be due to a faulty valve assembly inside the handle or faucet body. The most common cause of this type of leak is corrosion on O-rings and gaskets inside these components. The water pressure can build up until it forces water through these seals. This can happen gradually over time or suddenly after use or after turning off the water supply while running hot water in your shower.

Damaged Parts

If your tub spout is leaking from the back, then it’s possible that one or more of its components are damaged and need replacing. If you’ve had any problems with this type of fixture before, then there’s a good chance that some parts may have been damaged due to wear and tear over time. It’s always best to replace worn pieces immediately because if you don’t, you could end up paying more to fix them.

Make sure all parts are connected tightly before turning on your water supply again!
