I like this option because I can swap it out for a washing machine angle valve which helps me get water to the shower for thin-mortar and joint compound 🔥#plumbing #bathroomremodel #diy #sharkbiteplumbing #homerepairtutor | Home Repair Tutor | Facebook

Preparation and Measurement

Start by turning off the water supply to your shower. The main water supply valve should be located near your shower, usually behind the shower wall or in the basement. Once the water is off, open the shower faucet to relieve any remaining pressure.

Measure the distance between the valve openings on your wall and the center of the shower faucet you've purchased. This measurement will determine the location of your faucet. Mark these points on your wall using a pencil.

Cutting the Wall Opening

Using your hacksaw, cut along the lines you've marked. Be careful not to cut into any pipes or wires behind the wall. If you're unsure, consider using a multi-purpose detector tool to locate any hidden obstacles.

Once you've cut out the opening, you should have a rough hole that matches the size of your faucet. If not, adjust the hole until it's the correct size. Ensure the opening is large enough to accommodate the faucet's escutcheon (the decorative plate that covers the hole).

Installing the Valve Body

Insert the valve body through the hole from the back of the wall. The valve body should fit snugly against the wall. Use Teflon tape to wrap the threads of the valve body to prevent leaks. Then, screw the valve body into place using your screwdriver. Tighten it securely, but be careful not to overtighten and strip the threads.

From the front of the wall, apply a small amount of plumber's putty around the edge of the valve body. This will create a watertight seal. Press the escutcheon firmly against the putty, then screw it into place. Wipe away any excess putty that squeezes out.

Installing the Faucet Handles and Spout

Insert the faucet handles and spout through the front of the valve body. The handles should fit snugly onto the valve stem. Use the set screws provided with your faucet to secure the handles in place. Tighten these screws securely, but again, be careful not to overtighten.

Connect the water supply lines to the faucet. Ensure they're securely attached and there are no leaks. If your faucet has a diverter valve for the showerhead, install that now as well.

Testing the Faucet

Turn the water supply back on at the main valve. Allow the water to run through the faucet for a few minutes to clear any debris. Check for any leaks around the faucet or at the connections. If there are no leaks, your faucet is now installed and ready to use.

Test the faucet by turning the handles on and off. The water flow should be smooth and consistent. If you encounter any issues, double-check your connections and ensure everything is tightened securely.

Congratulations, you've successfully installed your shower faucet! Regular maintenance, such as cleaning the aerator and checking for leaks, will help keep your faucet in top condition. If you ever encounter any issues, don't hesitate to consult a professional plumber for assistance. Happy DIYing!
