Delta Single Handle Bathroom Faucet Cartridge Replacement

Replacing a Delta single handle bathroom faucet cartridge is a simple plumbing repair that can be completed in a few minutes. A cartridge is a small, cylindrical device that controls the flow of water in the faucet. When a cartridge wears out, it can cause the faucet to leak or become difficult to operate. Fortunately, replacing a cartridge is a relatively easy and inexpensive repair.

Materials Needed

* New Delta faucet cartridge (specific to your faucet model) * Adjustable wrench * Phillips screwdriver

Steps

1. Turn off the water supply to the faucet. There are usually 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. 2. Remove the handle. Use an adjustable wrench to loosen the handle screw. Once the screw is loose, pull the handle straight up to remove it from the stem. 3. Remove the cartridge retaining nut. Use an adjustable wrench to loosen the cartridge retaining nut. Once the nut is loose, remove it by hand. 4. Pull out the old cartridge. Grip the old cartridge and pull it straight out of the faucet body. 5. Insert the new cartridge. Insert the new cartridge into the faucet body. Make sure that the cartridge is properly seated in the body. 6. Tighten the cartridge retaining nut. Hand-tighten the cartridge retaining nut onto the faucet body. Use an adjustable wrench to further tighten the nut, but do not overtighten it. 7. Reattach the handle. Slide the handle down onto the stem and tighten the handle screw with an adjustable wrench. 8. Turn on the water supply and check for leaks. Open both shut-off valves under the sink to turn on the water supply. Check for any leaks around the handle or the base of the faucet. If you find any leaks, tighten the cartridge retaining nut or the handle screw as needed.
