Faucet replacement is a very easy task that anyone can do. Here are the basics that you should know about faucet replacement.
You should pick out a new faucet and have it on hand before you start to remove your old faucet. Having it on hand before removing the old one will make things easier and faster for you. For your bathtubs and sinks, you can get single or double handled faucets. Generally, faucets have a standard size regarding their hook-ups, depending on their use. For kitchen faucets, you can usually find units with an 8 inch hookup. Bathroom vanity faucets usually come in 4 inches, while bathtubs come in 8 inches.

First, you should turn off all water supply lines that are linked to your faucet. Once you have shut off your water supply you can remove the supply lines coming from both sides of your faucet. After that you should remove the large retainer nuts that are holding your faucet to the sink. When you are done with this, remove the old faucet from the sink. Clean up the area where the old unit was. Once you are done cleaning up, get your new unit and place it in the holes. Then you can tighten the retaining nuts and hook up your water supply lines. Use plumbers putty or thread tape to prevent leaks or dripping on the joints, specifically in between the faucet and sink, or the supply line and the faucet. Turn on your water supply and do some tests for leaks and other defects. If you have some leaks, try reinstalling it again and make sure that you tightly place each part where they should be.
