Troubleshooting Cartridge Problems

Low Water Pressure

Issue: The water flow from the faucet is weaker than usual.

Remedy:

Check the Aerator: Remove the aerator at the end of the faucet spout and clean any debris or mineral build-up.
Inspect the Cartridge: Shut off the water supply, remove the handle, and extract the cartridge. Clean or replace the cartridge if clogged.
Flush the Lines: Turn on the water supply without the cartridge installed to flush out any debris in the lines.
Reassemble: Reinstall the cartridge and handle, then test the water pressure.

Issue: The faucet continues to drip even when turned off.

Remedy:

Identify the Source: Determine if the drip is coming from the spout or the base of the faucet.
Replace the Cartridge: Shut off the water supply, remove the handle and the faulty cartridge, and replace it with a new one. Ensure the new cartridge matches the old one.
Check O-Rings: Inspect and replace any worn-out O-rings or seals.
Reassemble: Reinstall the handle and turn on the water supply to check for leaks.

Issue: The faucet handle is hard to turn or is stuck.

Remedy:

Lubricate the Cartridge: Shut off the water supply, remove the handle, and extract the cartridge. Apply a plumber’s grease to the cartridge stem.
Clean the Cartridge: If lubrication doesn’t help, soak the cartridge in vinegar or a lime remover to clean mineral deposits.
Replace if Necessary: If the handle is still difficult to turn, replace the cartridge.
