How to Change a Washer in a Single Handle Delta Bathroom Faucet

A leaky faucet can be a frustrating and wasteful problem. When a bathroom faucet starts to drip, it's often due to a worn-out washer. Fortunately, replacing a washer is a relatively simple maintenance task that most homeowners can do themselves, saving money on a plumber's call. This article will guide you through the process of changing a washer in a single handle Delta bathroom faucet.

Tools and Materials

Before you begin, you'll need to gather the following tools and materials:

Phillips head screwdriver
Adjustable wrench
Basin wrench
Needle-nose pliers
Replacement washer (ensure it's compatible with your faucet)
Thread sealant tape (optional)
Rag or towel

Steps to Replace the Washer

Now that you have all the necessary tools, you can proceed with the following steps:

Turn off the water supply. Locate the shut-off valves for the hot and cold water lines leading to your faucet. Turn these valves clockwise until they are completely closed. If you are unsure where the shut-off valves are located, check with your owner's manual or a plumber.
Remove the handle. Most Delta single handle faucets have a small set screw on the handle. Use a Phillips head screwdriver to loosen and remove this set screw. Once the screw is removed, gently pull the handle off the faucet stem.
Remove the cartridge. The cartridge is the internal component that controls the water flow. It's usually held in place by a retaining nut. Using the adjustable wrench, carefully loosen and remove this nut. The cartridge will then be free to remove.
Remove the old washer. The washer is a small rubber or plastic disc at the bottom of the cartridge. Use needle-nose pliers to carefully remove the old washer. Make sure you note the washer's size and type, as you'll need a replacement that matches.
Install the new washer. Place the new washer in the same position as the old one. If you are using a different type of washer, ensure it is compatible with your faucet. Ensure the new washer is securely seated on the cartridge.
Reassemble the faucet. Reverse the steps you took to disassemble the faucet. Place the cartridge back into the housing and tighten the retaining nut. Replace the handle and tighten the set screw.
Turn on the water supply. Slowly open the shut-off valves to allow water to flow through the faucet. Check for leaks at the handle and cartridge. If there are any leaks, repeat the process of tightening the retaining nut and set screw.

Additional Tips

Here are some additional tips for changing a washer in a single handle Delta bathroom faucet:

Clean the cartridge. Before installing the new washer, it's a good idea to clean the cartridge using a toothbrush and mild soapy water. This will help prevent any debris from clogging the valve later on.
Use thread sealant tape. Before reassembling the faucet, consider wrapping the cartridge threads with thread sealant tape. This will create a tighter seal and help prevent leaks.
Handle with care. Gently handle the cartridge and other internal parts to avoid damaging them. If you're unsure about any part of the process, it's best to consult a professional plumber.

By following these steps, you can successfully change a washer in your single handle Delta bathroom faucet and resolve the problem of a leaky faucet. Remember to always consult a professional if you are unsure about any part of the process or if you encounter any unexpected difficulties.
