- Turn off the main water valve in your home, preventing any accidental flooding if a pipe happens to break.
- Measure the distance from your faucet to the shutoff valves on your wall. This measurement will determine the length of the supply line that you need to purchase.
- Under the sink, locate the two inlets leading from the faucet, one for hot water and one for cold. Depending on the quality of your faucet, the pieces will be either copper, brass or PVC. Wrap the threads of one of the inlets with a strip of Teflon tape.
- Thread the larger end of your supply line to the threaded taped inlet. You may need a wrench to tighten the ends properly.
- Thread the other end of the supply line onto your shutoff valve. Tighten this end with a wrench to secure the hose in place.
- Repeat steps three and four for the remaining water inlet on your faucet.
- Reopen the main water valve you closed when you first started the project.
