Bathroom Faucet


If you can replace your own bathroom faucet, you are far ahead of the game and can save literally hundreds due to having a poorly functioning faucet as well as calling for professional plumbing help. The parts are fairly simple in most cases so, when you’re ready for a new fixture in your bathroom, gather your tools and get started.
Removing the Old Bathroom Faucet
  • Whenever working with plumbing fixtures of any kind, turn off the water supply to that fixture. If you don’t have a shut off valve for the fixture, use the main shut off outside the house.
  • There are supply tubes for both hot and cold water coming into separate valves. Loosen both.
  • Find the compression nut, located at the faucet stem, as well as the nut keeping the faucet held to the sink. Loosen and remove both, and you can remove the existing bathroom faucet.
  • Removing the pop-up drain requires locating and loosening three separate nuts; the nut above the P-trap, the one attached to it, and the lock nut that attaches the drain to the sink. Remove the P-trap and the pop up lever, and you can unscrew the drain.

Installing the New Bathroom Faucet

  • Always wrap connections with Teflon tape for best sealing results.
  • If there is a rubber gasket, install it on the base of the faucet. Otherwise, use caulk for sealing the in place.
  • Insert the faucet stems in the sink.
  • Secure nuts holding the faucet to the sink, then move to supply tubes, which need to be connected to the faucet stems.
  • Again, use Teflon on the threading for the shut off valves, and tighten coupling nuts on the faucet supply stems, being careful not to tighten too much and strip the threading.
  • Use caulk to seal the drain flange as you press it into the drain hole. The lock nut, followed by the washer and the gasket, should be applied to the housing before screwing the drain housing to the flange.
  • Drop the pop-up drain in and insert the control pin into the correct hole for proper functionality.
  • Insert the drain rod into faucet hole and screw to the faucet rod. Use the V-clip to connect the bail level.
  • Attach the drain to the P-trap.
  • Reconnect water supply and turn on to test the new bathroom faucet.
