How To Repair A Leaky Single Handle Bathroom Faucet

In this article, we will discuss some of the essential aspects of how to repair a leaky single handle bathroom faucet. Faucets are one of the most important fixtures in a bathroom, and a leaky faucet can be a major annoyance. Not only can it waste water and increase your water bill, but it can also create a mess and make your bathroom look unkempt. Fortunately, repairing a leaky single handle bathroom faucet is a relatively simple DIY project that can be completed in a few hours.

Before you begin, you will need to gather a few tools and materials. You will need a wrench, a screwdriver, a pair of pliers, and a new washer. You can find these items at any hardware store. Once you have your tools and materials, you can follow these steps to repair your leaky faucet:

Turn off the water supply to the faucet. 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.
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. Use a wrench to unscrew the aerator.
Remove the handle. On most faucets, the handle is held in place by a screw. Use a screwdriver to remove the screw, then pull the handle straight up to remove it.
Remove the cartridge. The cartridge is the part of the faucet that contains the seals that prevent water from leaking. Use a wrench to loosen the nut that holds the cartridge in place, then pull the cartridge straight out.
Replace the washer. The washer is a small, rubber ring that fits inside the cartridge. Over time, the washer can wear out and cause the faucet to leak. Use a pair of pliers to remove the old washer, then insert a new washer in its place.
Reassemble the faucet. Insert the cartridge back into the faucet, then tighten the nut that holds it in place. Insert the handle and secure it with the screw. Finally, screw the aerator back onto the faucet.

Once you have reassembled the faucet, turn on the water supply and check for leaks. If there are no leaks, you have successfully repaired your leaky single handle bathroom faucet!
