WOWOW FaucetsQuick Answer
To install a shower faucet, turn off the water, remove the old handle and trim, install the new rough-in valve or cartridge, attach the trim and handle, then restore water and check temperature, pressure, and leaks.
Before You Start
Turn off the hot and cold water, open the old faucet to release pressure, and have Teflon tape, an adjustable wrench, a screwdriver, and the manufacturer instructions ready.
Step by Step
1. Remove the old handle and escutcheon plate. 2. Remove the old cartridge or rough-in valve. 3. Install the new valve with Teflon tape. 4. Attach the trim plate and handle. 5. Restore water and purge air from the lines. 6. Test temperature, pressure, and leaks.
Common Mistakes
Over-tightening connections, skipping Teflon tape, or not purging air from the lines. If the plumbing requires moving pipes, hire a licensed plumber.
Frequently Asked Questions
Can I install a shower faucet without professional help?
Yes, if the existing plumbing is prepared and you have basic tools. If you need to move pipes or change the rough-in, call a plumber.
How long does it take to install a shower faucet?
A straightforward trim replacement usually takes 30 to 60 minutes. Replacing the rough-in valve can take one to two hours.
Why does my new shower faucet drip after installation?
A drip usually means the valve or cartridge is not seated correctly, the seals are damaged, or the connections need more thread sealant.
