Dripping Tub Faucet After Cartridge Replacement? Here's the Fix

09 Oct 2024

You thought you'd conquered the dripping faucet demon by replacing the cartridge, but the steady drip persists, mocking your DIY efforts. Don't despair, a leaky tub faucet after a cartridge replacement is a surprisingly common issue. This guide will walk you through the reasons why this happens and provide practical solutions to finally achieve that blissful silence.

A leaky faucet isn't just an annoyance; it's a constant drain on your water bill and a potential source of water damage. Replacing the cartridge is usually the right fix for a dripping faucet, as this crucial component controls the flow of water. So, when the drip continues after replacement, it can be incredibly frustrating.

The problem of leaky faucets dates back to the invention of indoor plumbing. As faucet designs became more complex, so did the potential points of failure. The introduction of cartridges simplified faucet repair, but even these can be installed incorrectly or be defective, leading to post-replacement leaks.

The primary issue with a tub faucet still leaking after cartridge replacement is often related to improper installation, a faulty new cartridge, or damage to other components of the faucet assembly. Identifying the source of the leak is the first step towards fixing it. Don't assume you need a plumber just yet – many of these issues can be resolved with a little troubleshooting.

Before diving into solutions, let's define what a cartridge is. It's the internal valve mechanism within your faucet that controls the flow and temperature of the water. It's typically cylindrical and made of plastic or brass. Different faucets use different cartridge types, so ensuring you have the correct replacement cartridge is crucial.

If you've recently replaced the cartridge and the faucet still leaks, start by double-checking the installation. Make sure the cartridge is properly seated and aligned. Even a slightly off-kilter cartridge can cause leaks. If the cartridge appears correctly installed, consider the possibility of a defective new cartridge. While rare, it can happen. Finally, inspect the O-rings and seals within the faucet assembly. These small rubber rings can become worn or damaged, requiring replacement.

Step-by-step guide to troubleshooting a leaky tub faucet after cartridge replacement:

1. Turn off the water supply to the tub.

2. Disassemble the faucet handle and remove the newly installed cartridge.

3. Inspect the cartridge for any signs of damage or debris.

4. Check the O-rings and seals for wear and tear. Replace if necessary.

5. Ensure the cartridge is the correct model for your faucet.

6. Reinstall the cartridge carefully, ensuring proper alignment.

7. Turn the water supply back on and check for leaks.
