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.
No Water Flow in Shower After Replacing Thermostatic Cartridge
Problem: After replacing the thermostatic cartridge in a shower valve, there is no water flow, although the shutoff and check valves are open.
Solution: The existing thermostatic cartridge broke into pieces in the valve and some of the pieces remain in the valve body. Remove any remains of the existing cartridge from the valve body, then install the new thermostatic cartridge.
