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.

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.

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.

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.
