How To Install a Bathroom Faucet : Bathroom Faucet

Installation of a bathroom faucet or washbasin faucet is basically a DIY plumbing project.

Most home owners with little hands-on experience in plumbing can install a faucet in their bathroom.

The only hard thing to do is to make adjustments under the washbasin.

There, I recommend to free up the area before starting the plumbing and installation.

Tools and Material Needed to Install a Bathroom Faucet:

  1. Drain – 1 No.
  2. Faucet – 1 No.
  3. Stop Valves if Required – 2 Nos.
  4. Flexible Metal Braided Lines – 2 Nos.
  5. Putty for Sealing
  6. Teflon Tape / Plumber’s Tape
  7. Penetrating Oil such as WD-40
  8. Adjustable Wrench
  9. Basin Wrench / Sink Wrench
  10. Slip Joint Pliers

Step By Step Instructions on How to Install a Bathroom Faucet

  1. Cut Water Supply – The first step is to cut water supply to the basin. Most washbasins have a water feed pipe. There is a “shutoff” at the supply point. Turn it off. If there is no option to cut off water supply to the washbasin, then cut off the main water supply.
  2. Remove Old Pipes and Nuts – If you are replacing an existing faucet, loosen the nuts and the existing flexible braided metal lines under the washbasin. Unscrew all nuts including the union nuts and lock nuts. Use a basin wrench for the purpose. If the nuts are too rusty to open, spray WD-40 penetrating oil and wait for few minutes before removing them.
  3. Remove The Old Faucet – Remove the existing faucet and existing feed pipes. If there is any sealer near the holes, use a putty knife to scrape and clean the surface.
  4. Replace the Old Feed Pipes – Replace the old feed pipes with the new flexible metal braided lines.
  5. Remove the old mechanical plug.
  6. Apply Sealer and Install the New Faucet – Apply a thick layer (about 6 mm) of plumbers putty on the base of the faucet. Insert the faucet in the hole and apply little pressure downwards so that the putty adheres to the base of the faucet. This will give a watertight joint. Apply some Teflon tape to the threaded ends of the tailpiece of the faucet and tighten the lock nut using a basin wrench. Once the nuts are tight, remove any excess putty from the base of the faucet and clean the area.
  7. Connect the Braided Supply Lines – Connect one end of the new flexible metal braided supply lines to the faucet tailpieces and the other end to the shutoffs. Tighten the nuts using an adjustable wrench. Don’t make it too much tight or it can damage the supply line.
  8. Install The Mechanical Plug – Follow the manufacturer’s instructions to install the mechanical plug. Make sure to apply Teflon tape, putty and washer.
  9. Check all Connections and Turn On the Water Supply – If all connections are ok, turn on the water supply and let the water flow for few minutes to discharge any dirt inside the faucet.
