How to Convert a 3-Handle Shower Faucet to a Single-Handle Valve · Step 7 of 9
In this video
Return to the main water shut-off valve and turn it counter-clockwise to slowly restore water to the house. You may hear pipes gurgling as they refill. Once the water is back on, go to the shower and turn the handle to test the newly installed cartridge. Check for proper hot and cold water flow and, most importantly, turn the faucet off and check for any leaks from around the handle or out of the tub spout. If there are no leaks and the faucet operates smoothly, the repair is complete.
Goal: Verify the repair
- Turn the water back on slowly to avoid a 'water hammer' effect, which can damage pipes.

FAQs
This project is rated 'intermediate.' What specific skills or prior experience are essential for successfully converting a three-handle shower faucet?
An intermediate rating means you should be comfortable with basic plumbing tasks, including cutting pipes and making secure connections. Experience with soldering copper pipes is crucial, as the new valve typically requires soldered connections. You'll also need basic carpentry skills for opening and repairing the access wall.
The estimated time is 16 hours. What aspects of this conversion project take the most time, and can it be completed in a single weekend?
The 16-hour estimate accounts for significant stages like creating wall access, carefully removing the old valve, precisely soldering the new one, and thorough leak testing. Repairing and finishing the access wall also adds considerable time. While possible to do in a weekend, spreading it over a few days allows for drying times and meticulous work, especially for leak checks.
What are the critical safety considerations, especially regarding soldering and working with plumbing behind the wall?
Always turn off the main water supply before starting. When soldering, ensure excellent ventilation to disperse fumes and have a fire extinguisher nearby; protect surrounding studs with a heat shield. Wear appropriate PPE, including safety glasses and gloves. Thoroughly drain pipes to avoid steam buildup during soldering.
What are the most common mistakes DIYers make during this type of shower valve conversion, and how can they be avoided?
A common mistake is improper soldering, leading to leaks. Ensure pipes are clean, flux is applied correctly, and joints are heated evenly. Another error is not thoroughly leak testing before closing the wall; pressurized water should run for several hours. Also, double-check the new valve's orientation and depth before securing it.
