Preparation and Removal of the Old Faucet

Begin by turning off the water supply to your shower. The valves are usually located behind the shower wall, so you might need to remove a panel for access. Once the water is off, open the faucet to release any remaining pressure.

Using an adjustable wrench, loosen and remove the nuts connecting the old faucet to the plumbing. You may need to use a screwdriver to remove any set screws holding the faucet in place. Carefully remove the old faucet, taking note of how the parts are connected for reference during the new installation.

Inspect and Prepare the Plumbing

Examine the exposed plumbing for any signs of damage or leaks. If necessary, replace any worn-out parts before installing the new faucet. Clean the area to remove any debris or old plumber's putty.

Before installing the new faucet, ensure the threads on the plumbing are clean and free of any old tape or putty. If the threads are damaged or stripped, you may need to replace the plumbing nipples.

Install the New Faucet

Start by wrapping the threads of the faucet's water inlet with Teflon tape. This helps create a watertight seal and prevents leaks. Screw the faucet onto the plumbing, using an adjustable wrench to tighten it securely but be careful not to overtighten and damage the threads.

Connect the faucet's supply lines to the water supply valves. Ensure the hot and cold lines are connected correctly to avoid scalding water. Use a wrench to tighten the connections, but again, be careful not to overtighten.

Final Checks and Testing

Before turning the water back on, double-check that all connections are secure and there are no obvious leaks. Once you're satisfied with the installation, slowly turn the water supply valves back on.

Test the faucet by turning it on and off, checking for any leaks around the connections or the base of the faucet. If there are no leaks, your new delta tub shower faucet is now installed and ready to use.
