Repairing the Leaky Faucet: Fix Leaky Delta Bathroom Faucet

Now that you’ve identified the source of the leak and gathered your tools, it’s time to tackle the repair. The process involves replacing the faulty component and tightening any loose parts.

Replacing the Cartridge

The cartridge is the heart of your Delta bathroom faucet, controlling water flow. Replacing a worn-out cartridge is often the solution for a leaky faucet.

Turn off the water supply to the faucet. Locate the shut-off valves under the sink and turn them clockwise to stop the water flow.
Remove the faucet handle by unscrewing it counter-clockwise. This might require a special tool depending on the faucet design.
Remove the faucet cap. The cap sits on top of the cartridge and usually has a screw holding it in place.
Pull out the old cartridge. Once the cap is removed, you can gently pull the cartridge out. Take note of the orientation of the cartridge for proper reinstallation.
Install the new cartridge. Insert the new cartridge into the faucet body, ensuring it’s aligned correctly. Push it firmly until it clicks into place.
Reassemble the faucet by replacing the cap, handle, and turning the water supply back on.

Replacing the Washer

The washer is a small rubber ring that sits inside the faucet spout, sealing the water flow. A worn-out or damaged washer can lead to leaks.

Turn off the water supply to the faucet.
Remove the faucet spout by unscrewing it counter-clockwise. The spout is usually held in place by a nut underneath.
Remove the old washer from the spout.
Install the new washer in the spout, ensuring it’s properly seated.
Reassemble the faucet by screwing the spout back in place and turning the water supply back on.

Replacing the O-ring

O-rings are small rubber rings that seal different parts of the faucet. A worn-out O-ring can cause leaks at the handle or spout.

Turn off the water supply to the faucet.
Disassemble the faucet according to the specific model instructions. This may involve removing the handle, cap, or other components.
Locate the O-ring. The O-ring is usually found in the handle assembly, spout, or other parts of the faucet.
Replace the O-ring with a new one. Ensure the new O-ring is properly seated in the groove.
