This project demonstrates how to replace a Delta shower faucet with a Delta Monitor series faucet. The steps include: 1. **Shut Off the Water Supply:** Turn off the main water supply to the house and double-check that the water is off at the shower faucet. 2. **Remove the Old Shower Trim:** Carefully remove the handle and escutcheon plate, taking photos as you go to help with reassembly. 3. **Remove the Old Delta Valve:** Remove the old valve, which might involve unscrewing it or cutting it out depending on the type of installation. Use pliers or an adjustable wrench for any retaining nuts or clips. 4. **Install the New Delta Monitor Valve and Trim:** Install the new valve and trim according to the manufacturer's instructions, making sure parts are aligned correctly and replacing washers if needed. 5. **Test for Leaks and Adjust Temperature:** Slowly turn the water supply back on and check all connections for leaks. Adjust the temperature as needed. If leaks continue, double-check the installation, especially the tightness of the fittings.
