How To Install A Kitchen Sink Faucet?

Drain Water Pipes

– First of all, you need to shut the water supply off at the main valve. After that, you should open up all the faucets in your house to drain water from the pipes. 

Do Necessary Preparations

– Look underneath the kitchen sink you are installing the faucet at. You will find two water lines that run up to the faucet. Find out which one is the hot water line and which one is cold. The hot water line is connected to the dishwasher. 

– Turn off any electric switches and electrical equipment. Make sure that your area is safe before you start working on the water lines. 

– You might need some towels as there will be some residual water which will come out when you release the water line. 

– You might need pipe wrenches to remove the water lines

Remove Water Lines

- Locate the valves of the hot and cold water pipes. Remove the water line from both the valves using the wrenches. 

- Disconnect the water lines after unscrewing the nuts at the faucet connection. 

- Unscrew the mounting nuts. After you remove the mounting nuts, the faucet will be free to be lifted out of the sink.
