Faucet Drips After Installing New Cartridge
Problem: Limescale or mineral deposits on the faucet valve is preventing a proper seal between the bottom of the cartridge and the top of the valve.
Solution: Soak the faucet valve in distilled clear vinegar for several hours to remove limescale from surfaces. Then use an old toothbrush to remove any remaining calcium deposits. Install the new cartridge, making sure not to under-tighten or over-tighten the cartridge.
