Why does my Project Source Plumbing Product faucet leak underneath the handle?
- MMary MathewsAug 10, 2025
The faucet leaks underneath the handle because the bonnet has come loose or the ceramic cartridge seal is dirty or out of place. To resolve this, move the handle to the OFF position, unscrew the handle screw, and remove the handle. Tighten the bonnet clockwise. If the leak persists, shut off the water supply, remove the bonnet, and lift out the ceramic cartridge. Inspect the seal, remove any debris, and re-seat it if necessary. If the seal is worn, replace the cartridge. Finally, position the cartridge back, screw the bonnet on tightly, and reinstall the handle.
