Faucet

Whether you need to install a new bathroom sink and faucet or replace an existing faucet that is not working properly, knowing how to do either can save you the cost of an expensive plumber’s fee. Though steps for installation may vary according to plumbing design and installation, but the process will be relatively simple. You can insert the faucet parts into place before adding the sink. It is important to remember that before purchasing your new faucet you determine the size and number of plumbing holes in your sink, so the faucet will fit. Other than that, the following tips will assist you in the installation process.

Removing the Existing Faucet

If you are replacing an existing faucet, you will need to remove the faucet already in place. Position yourself beneath the sink to perform this function. If the nuts connecting supply tubes to faucet tail pieces are hard to reach, you'll lfind that using a basin wrench works well, because of its longer handle. Before removing the faucet, turn off the water shut-off valves.

Use the basin wrench to remove the nuts that attach the supply tubes and the faucet tailpieces together. Once the nuts are removed, you'll find it easier to keep dry if you have a bucket handy to catch water that drips or drains from the supply tubes. On the tailpiece of your faucet you will find lock nuts and washers, all of which you will need to remove. Once these have been removed, you will then be able to take the old faucet from the sink.

Assembling the Faucet

Most new faucets need to be assembled before installing them in the sink. If you have a owner's manual, you should follow its directions to assemble faucet components.

Cleaning the Faucet Surface

If you are installing a faucet to replace an old one, you should clean dirt or grime from the faucet base area.

Inserting the Rubber Gasket

You will need to insert the rubber gasket that fits between the sink and the base plate to create a watertight seal. Sometimes a rubber gasket is not supplied, if this is the case with your new sink, you will need to seal the area around the base of the faucet with plumber’s putty. You will then be able to thread the tailpieces through the holes in the faucet and into the top of the sink without concern that it will leak.

Inserting the Water-Supply Tubes

You can feed the water supply tubes through the hole in the middle of your sink. These tubes will be attached to your faucet. Once this is done, you'll be able to press the faucet down, so it is situated correctly in the sink.

Thread Washer and Mounting Nuts

Once your faucet is in place, you can add a washer and mounting nut and connect them to the tailpiece. Just a final tightening of the nuts with a wrench, and you should have your project finished.
