While it may seem like a project for a trained plumber, changing out an old faucet for a new one is fairly simple if you follow the steps closely. The process itself just takes a few household tools and would likely take the average joe no more than an hour to get it done. So, if you’re in need of a new faucet, learn how to replace the old one yourself!
Material and Tools
- Bathroom or kitchen faucet
- Supply lines
- Silicone caulk
- Basin wrench
- Adjustable wrenches
- Paint thinner
- Putty knife
Before buying a new faucet, first make sure it fits your sink, which should have one, two, or three holes for the faucet. The hole or holes will either be widespread or centerset, so know this before you head out to the store. You can even take your old faucet with you.
Directions for Replacing the Bathroom Faucet
Removing the Old Faucet
- Before you begin, shut off the sink’s water supply. Those valves should be under the sink, but, if not, shut off the water supply using the main valve. Switch on the faucet to release any pressure in the water lines.
- Detach the water supply lines from the faucet. You can use your basin wrench if you can’t grasp the connections using your hands.
- Detach the sink’s lift rod before removing the nuts under your old faucet.
Removing the Drain
- Remove the slip nut from the P-trap. Place a bucket beneath to catch any water from the trap.
- Detach the drain flange from off the tailpiece by unscrewing it.
- Clean up around the drain and the faucet holes. You can use paint thinner to try and remove any leftover silicone sealant.
Installing the New Faucet
- For the new faucet, there should be detailed installation instructions. It should start with you installing the gasket to the bottom end of the faucet (some may necessitate plumber’s putty or sealant). Put the faucet through the sink’s mounting holes, and then tighten the mounting nuts.
- Since not every faucet comes preassembled, you may need to attach both handles. Just slip the guide ring to the handle bottom, place it on the faucet base, and fasten it with the setscrew, which is a small screw on the handle’s underside. The new faucet’s packaging likely included a hex wrench for tightening it.
- For the drain, screw on the nut down onto the drain body, pushing the gasket over it.
- Apply some silicone or plumber’s putty beneath the flange. Set the drain body on the bottom of the sink (make sure the pivot hole faces backwards) and screw on the flange from the topside.
- Below, tighten the gasket and nut. Up top, use paint thinner to clean any surplus silicone.
- Next, install the drain rod. Loosen the pivot nut on the drain body, push the horizontal rod through the stopper hole, and then replace the nut. Push down the horizontal rod and attach the lift rod to the strap using the screw. Now, test the lift rod.
- Reattach the water supply lines to your new faucet. If the sink is in place already, use the basin wrench for the faucet shanks.
- Remove the aerator to flush the faucet, which should get rid of any sediment or debris in the faucet. Switch on the cold and hot water for roughly one minute. Then, check every connection for any leaks, retightening if you must. Finally, screw the aerator back on.
