Installation Instructions

Follow these steps to replace the faucet cartridge:

  1. Turn Off Water Supply: Locate the main water shut-off valve for your home or the specific shut-off valves for the faucet (hot and cold). Turn them off completely.
  2. Relieve Water Pressure: Open the faucet handles to drain any remaining water and relieve pressure in the lines. Close the handles once water stops flowing.
  3. Remove Faucet Handle: Depending on your faucet model, you may need to pry off a decorative cap to expose a set screw. Use an Allen wrench or screwdriver to loosen and remove the set screw, then pull the handle off the faucet stem.
