Before starting any work on the faucet, you must shut off the water to the house. Locate the main water shut-off valve and turn it to the off position. To drain the remaining water from the plumbing system, go outside and open a hose bib or open the faucet at the lowest point in the house. Return to the bathroom and open the hot and cold handles on the old faucet to release any trapped water and pressure. It is also a good safety practice to turn off the circuit breaker for the electric water heater to prevent it from running dry.
Goal: Prepare Plumbing System for Safe Work
- Failure to shut off the water will result in flooding. Double-check that the water is completely off before disconnecting any pipes.
- The on-screen text advises closing the hose bib after the system is drained to prevent siphoning water from the water heater.

FAQs
What if my outdoor faucet is leaking from the handle or spout, not the intake connection?
This guide specifically addresses leaks at the supply pipe connection (the intake). Leaks from the handle or spout usually indicate worn-out internal components like a packing nut or washer, which require a different repair process. You'd likely need to replace specific internal parts, not just reseal the threads on the supply pipe.
Why is it important to use two wrenches when disconnecting the supply pipe?
Using two wrenches—one to hold the existing pipe steady and the other to turn the faucet—prevents twisting and damaging your home's main water supply pipes. Twisting can lead to a larger, more serious leak inside your wall or foundation, making this a critical safety step.
Can I use pipe dope instead of or in addition to Teflon tape for sealing the threads?
Yes, you can use pipe dope in addition to Teflon tape for an extra layer of sealing security, especially for outdoor connections. Apply 4-6 wraps of Teflon tape clockwise to the male threads first, then a thin layer of pipe dope over it. While pipe dope alone can work, the combination offers superior leak prevention for threaded connections.
I've reconnected everything, but the intake connection is still leaking slightly. What should I do?
First, ensure the water supply is completely off again. The most common issues are insufficient Teflon tape, incorrect application (not clockwise), or damaged threads. Disassemble, clean threads thoroughly with a wire brush, apply 4-6 wraps of Teflon tape clockwise, and ensure the connection is tightened firmly but without overtightening. Inspect the threads for pitting or major damage.
