How To Remove And Install Bathtub Faucet Cartridge

A bathtub faucet cartridge is a small but important part of your bathroom plumbing. It controls the flow of water and temperature. If your cartridge is damaged or worn out, you may experience leaks, drips, or difficulty controlling the water flow. Replacing a bathtub faucet cartridge is a relatively simple task that can be completed in about 30 minutes.

Here are the steps on how to remove and install a bathtub faucet cartridge:

Turn off the water supply. The first step is to turn off the water supply to your bathtub. There should be two shut-off valves under the sink, one for the hot water and one for the cold water. Turn both valves clockwise to turn off the water.
Remove the handle. Once the water supply is turned off, you can remove the handle. Most handles are held in place by a screw. Use a screwdriver to remove the screw, then pull the handle straight off.
Remove the cartridge. The cartridge is located behind the handle. Use a wrench to loosen the packing nut that holds the cartridge in place. Once the packing nut is loose, you can pull the cartridge straight out.
Inspect the cartridge. Once the cartridge is removed, you can inspect it for damage. If the cartridge is damaged, it will need to be replaced.
Install the new cartridge. If the cartridge is damaged, you will need to install a new one. Insert the new cartridge into the faucet body and tighten the packing nut. Do not overtighten the packing nut, as this can damage the cartridge.
Reinstall the handle. Once the cartridge is installed, you can reinstall the handle. Align the handle with the cartridge and push it on until it clicks into place. Tighten the screw that holds the handle in place.
Turn on the water supply. Once the handle is installed, you can turn on the water supply. Check for leaks around the cartridge and handle. If there are any leaks, tighten the packing nut or handle screw as needed.

Replacing a bathtub faucet cartridge is a simple task that can be completed in about 30 minutes. By following these steps, you can save yourself the cost of calling a plumber.
