Slowly turn the water supply back on and check all new connections for leaks. The video shows leaks dripping from the threaded fittings. The water is shut off again, and the system is drained. The leaking threaded fittings are tightened further with an adjustable wrench. This process is repeated until no leaks are present.

Goal: Ensure a leak-free installation

  • Even with Teflon tape, threaded fittings may need to be tightened further after initial pressurization to stop drips.

FAQs

Do I absolutely need specific tools like an adjustable wrench and 6-in-1 screwdriver, or can I use alternatives?

An adjustable wrench is highly recommended for proper leverage and grip on the shower head, reducing the risk of stripping. The 6-in-1 screwdriver covers various screw types for the handle. Penetrating oil is also a very helpful addition for stuck parts.

The project says 'beginner' and '2 hours.' Is that realistic for someone with no plumbing experience?

Yes, this project is generally beginner-friendly if you follow the steps carefully. The 2-hour estimate is realistic, but if old parts are corroded or seized, it might take longer. Patience and preparation are key to success.

What's the best way to deal with a shower head or handle that's seized and won't budge?

For a seized shower head, generously apply penetrating oil to the threads and let it sit for 15-30 minutes before trying the wrench again. For a stuck handle, double-check for hidden set screws or snap-on caps before carefully prying with a putty knife.

I've turned the water back on, and now I have a small leak. What should I check first?

First, ensure all connections, especially those involving the shower arm and new shower head, are tight but not overtightened. If the leak persists, try reapplying new Teflon tape (plumber's tape) to all threaded connections, ensuring a good seal.

We got to go feed animals now.
