Updating a sink with a Pegasus faucet, known for their fine quality, will add a luxurious look to a bathroom or kitchen. Installing a Pegasus faucet can be done by the homeowner, saving money that would otherwise be spent hiring a plumber. With the right tools and a little preparation the job should not take more than an hour even for a novice.
-
Turn off the water supply to the faucet by turning the shut-offs under the sink all the way to the right. If there are no shut-offs under the sink, the main water shut-off for the entire house will have to be turned off.
-
Remove the old faucet by first using the adjustable wrench to unscrew the water supply lines from the shut-offs or the water pipe and from the faucet stems.
-
Unscrew the nuts on the faucet stems under the sink by using the basin wrench. Remove the old faucet and clean the area with mineral spirits and an old rag.
-
Roll the plumber's putty into a long enough piece to go around the entire base of the new faucet. If the new faucet has separate pieces, place plumber's putty around the base of each piece.
-
Put the new faucet in place making sure it is straight. Fasten the nuts onto the faucet stems underneath the sink with the basin wrench.
-
Attach the new water supply lines to the ends of the faucet stems and to the shut-offs or, if no shut-offs, to the water pipes. Do not overtighten.
-
Turn on the water. If there are any drips, tighten the nut where the drip is coming from a little at a time until the drip stops.
