Take the two 90-degree elbow pipes. Wrap the male threads of each pipe with sealing tape (Teflon tape) two to three times in a clockwise direction. This ensures a watertight seal. Once wrapped, screw the elbow pipes into the hot and cold water outlets on the wall by hand until snug.

- Pay close attention to which pipe is hot and which is cold. If the hot and cold water pipes are reversed, the thermostat function may not work properly.

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.
