How to Fix a Leaky Bathroom Tub Faucet with Single Handle

A leaky bathroom tub faucet is a common plumbing issue that can waste water and money. Fortunately, it's usually a relatively easy fix that you can do yourself with a few basic tools. In this article, we'll provide step-by-step instructions on how to fix a leaky single-handle bathroom tub faucet.

Tools and Materials You'll Need:

Adjustable wrench
Allen wrench or hex key
Screwdriver
Replacement cartridge (if necessary)
Plumber's putty
Teflon tape

Step-by-Step Instructions:

Turn off the water supply: Locate the shut-off valves under the sink or behind the toilet and turn them off.
Remove the handle: Use the Allen wrench or hex key to remove the screw holding the handle in place. Pull the handle straight off the faucet.
Remove the cap: Underneath the handle, you'll see a cap or escutcheon. Use the screwdriver to remove the screw(s) holding it in place and lift it off.
Unscrew the cartridge: Using the adjustable wrench, loosen the nut holding the cartridge in place. Pull the cartridge straight out of the faucet body.
Inspect the cartridge: Examine the cartridge for any visible damage or wear. If it's damaged, replace it with a new one.
Apply plumber's putty: Apply a thin layer of plumber's putty around the base of the new cartridge (or the old one if it's not damaged).
Insert the cartridge: Push the cartridge into the faucet body and tighten the nut using the adjustable wrench.
Wrap Teflon tape: Wrap a few layers of Teflon tape around the threads of the cap.
Replace the cap: Screw the cap back onto the faucet body.
Replace the handle: Align the handle with the faucet and insert it onto the stem. Tighten the screw using the Allen wrench or hex key.
Turn on the water supply: Open the shut-off valves to restore water flow.
Check for leaks: Turn on the faucet and check for any leaks around the handle, cap, or base of the faucet.

Tips:

If the leak persists after replacing the cartridge or performing any other repair, it may be necessary to contact a licensed plumber.
Regular maintenance can help prevent leaks from developing. Clean the faucet aerator and remove any calcium or mineral buildup.
If the faucet is old or heavily worn, it may be more cost-effective to replace it with a new one.

By following these steps, you can fix a leaky single-handle bathroom tub faucet and restore it to proper working condition. This repair typically takes less than an hour and can save you significant money in water bills and plumbing expenses.
