How to Fix a Leaking Bathroom Faucet with One Handle

A leaking faucet is a common problem that can waste water and increase your water bill. If you have a leaking bathroom faucet with one handle, you can usually fix it yourself with a few simple tools. Here are the essential aspects of how to fix a leaking bathroom faucet with one handle:

Identify the Type of Faucet

There are two main types of single-handle bathroom faucets: cartridge faucets and ball faucets. Cartridge faucets have a removable cartridge that controls the flow of water. Ball faucets have a ball-shaped valve that controls the flow of water. Identifying the type of faucet you have is the first step to fixing the leak.

Gather the Necessary Tools

To fix a leaking bathroom faucet, you will need the following tools:

Adjustable wrench
Phillips head screwdriver
Flat head screwdriver
Replacement cartridge or ball (if necessary)
Plumber's putty
Rags

Step-by-Step Instructions

The following are the step-by-step instructions on how to fix a leaking bathroom faucet with one handle:

Turn off the water supply to the faucet. There should be two shut-off valves under the sink, one for hot water and one for cold water. Turn both valves clockwise to turn off the water supply.
Open the faucet to release any remaining water in the lines.
Remove the aerator. The aerator is the small, screen-like device at the end of the faucet spout. Use a wrench to unscrew the aerator.
Remove the handle. The handle is usually held in place by a screw. Use a screwdriver to remove the screw and then pull the handle off.
Remove the cartridge or ball. The cartridge or ball is located behind the handle. Use a wrench to loosen the nut that holds the cartridge or ball in place. Then, pull the cartridge or ball out.
Inspect the cartridge or ball. Look for any cracks or damage. If the cartridge or ball is damaged, it will need to be replaced.
Apply plumber's putty to the new cartridge or ball. Plumber's putty is a type of sealant that will help to create a watertight seal.
Insert the new cartridge or ball into the faucet. Tighten the nut that holds the cartridge or ball in place.
Reattach the handle. Push the handle onto the faucet and then tighten the screw that holds it in place.
Reattach the aerator. Screw the aerator back onto the faucet spout.
Turn on the water supply to the faucet. Check for leaks.

Conclusion

Fixing a leaking bathroom faucet with one handle is a relatively simple task that can be completed in a few minutes. By following the steps outlined above, you can save yourself the cost of calling a plumber.
