To install new widespread bathroom sink faucets, you will basically put together the parts provided in the box, using the existing holes that are already in the sink. When buying a sink faucet, make sure to get one that will fit the existing holes of the sink.
Removing an Existing Sink Faucet
If you are replacing the old sink faucet, the first step in installing the new one is to remove the old one. Start by turning off the shut-off valves for the faucet’s supply tubes. The supply tubes will be filled with water so place a bucket under the tubes for the water to drain into. Use a wrench to remove the supply tube nuts from the faucet tailpieces and use a basin wrench to remove the washers and lock-nuts on both tailpieces. Remove the old faucet and set it aside to properly dispose of.
Installing a New Faucet
Before installing a new faucet into existing bathroom fixtures remove the packaging and inspect the parts to make sure there are no damages and ensure all of the needed parts are there. To install a new faucet into existing bathroom fixtures:
What You’ll Need:
• Basin wrench
• Adjustable wrench
• Teflon tape
1.Turn off the hot and cold water supply to the sink and open the faucet valves to drain the water out of the faucet and into the sink.
2.Use a basin wrench to loosen the supply line nuts on the bottom of the existing faucet and remove the faucet. If the parts are rusty and difficult to remove, use penetrating oil to help with the removal.
3.Prepare the surface area of the sink for the new faucet by thoroughly cleaning faucet area, especially around the holes on the sink. Make sure to remove all hard water deposits and old caulking.
4.Set the new bathroom faucet in place by using the gasket seal if one is provided. If the new faucet doesn’t have a gasket, apply caulking or plumbers putty on the bottom of the faucet to create a seal.
5.Insert the new faucet into the holes, making sure it is properly aligned on the top of the sink.
6.Use a basin wrench to tighten the nuts under the modern bathroom vanity sink until the faucet is secure.
7.Wrap the Teflon tape around the fittings where the water supply lines will be connected (wrap in the same direction the nuts turn onto the fittings).
8.Connect the supply lines to the faucet, matching cold and hot and then use an adjustable wrench to tighten the supply line connectors.
9.Remove the aerator from the spigot, turn on the water supply, open the faucet valves and check for leaks and then replace the aerator.
If your sink has old, metal supply lines you should consider replacing them with new, flexible lines. The best time to replace existing water supply lines with new ones is when you are replacing the bathroom faucets.
