Turn the shower's water supply on to test the new system. Carefully check all connection points for any drips or leaks. Use the diverter valve to switch the water flow between the rainfall head and the handheld wand. Test all the different spray functions on the handheld wand by rotating the dial on its face. Ensure everything is working as expected.

FAQs

What should I do if I can't find or turn off the main water supply to my house or apartment?

Locating and shutting off the main water supply is the most critical first step. If you can't find it, check your water heater for a shut-off valve, or contact your building manager or a professional plumber. Do not proceed with the project until the water supply is completely off to avoid significant water damage.

Besides the screwdriver and adjustable wrench, are there any other essential supplies or tools I might need for this tub faucet replacement?

Yes, it's highly recommended to have plumber's tape (Teflon tape) for sealing threads, penetrating oil for loosening stuck or corroded old parts, and a small wire brush for cleaning debris. You might also find a basin wrench helpful for reaching nuts in tight spaces behind the tub wall.

I've replaced everything and turned the water back on, but the faucet is still leaking. What should I check first?

First, re-check that the new valve stems are fully seated and securely tightened, but not overtightened. Ensure all O-rings are correctly positioned and intact, as a misplaced or damaged O-ring is a common cause of leaks. Also, verify that the connections to the water supply lines are tight and sealed with plumber's tape.

Is 4 hours a realistic estimate for a complete beginner, or should I budget more time, especially if I encounter stuck parts?

While 4 hours is a good estimate for someone with some DIY experience and no major issues, a complete beginner should budget more, perhaps 6-8 hours. Encountering corroded or stuck parts, or making unexpected trips to the hardware store for forgotten items, can significantly extend the project time.
