How to Replace Kitchen Faucet – A Complete Guide


When you have purchased the best kitchen faucet for your dream home, the next step is to replace it with the existing one. To replace an existing kitchen faucet with a new one you need to remove the old kitchen faucet and then install a new one. But while you remove your existing kitchen faucet you may run into all kinds of problems, for example, tarnished pipes, tough nuts, and inaccessible fittings. Once you have overcome all these hurdles while removing your old kitchen faucet, you can then easily install the new kitchen faucet using the installation guide that comes with the faucet.

To remove an existing kitchen faucet, firstly you need to remove the drain lines from the faucet. Detach the drain lines and P-traps for easy access to the faucet and water supply lines. Place a bucket underneath the P-trap to collect any remaining water. Check for shutoff valves underneath the sink. If you have them already installed, check if they are working properly and if they are missing, buy easy-to-install solderless compression fitting valves or whichever type goes with your pipe. If you’re installing and replacing a valve, close the main water supply line and open the kitchen faucet to release pressure. Then cut the supply lines directly below the fittings using a tube cutter or hacksaw. Also, buy new stainless steel sleeved supply tubes for reliable water supply and basin wrench for loosening or tightening nuts. Remove the drain lines using a pipe wrench and for disconnecting and fixing the water lines.

Next, if you have a garbage disposer remove it by unplugging it and shutting off the circuit breaker if it is directly connected. Also detach the dishwasher discharge line and release the disposer by tapping the retainer ring with a hammer in a clockwise direction. Make sure there are rags underneath it to cushion its fall. Use a basin wrench to loosen tailpiece nuts by turning them counter clockwise. Unplug the spray nozzle hose and remove the faucet. Once the faucet is safely removed, clean the surface where the faucet was placed in order to install the new faucet.

Insert the flange in the faucet opening and follow the manufacturer’s installation instructions. Gradually tighten the flange nuts underneath the sink while adjusting the alignment of the flange, faucet and sink hole from the top. Thread the feeder lines through the flange and sink holes after ensuring the operation of the faucet and placement of the handle in the right direction. Use a faucet washer and tighten the faucet mounting nut from underneath while gently spreading the supply tubes. Use a wrench to tighten the faucet nut. Next, attach the spray hose to the faucet supply tube by threading the spray hose fitting on the faucet supply tube and then tighten it. Remove the nozzle out of the faucet so that it operates freely and attach the counterweight as per manufacturer’s instructions. Next, tighten the valves on the supply tubes and cut the feeder lines just above the compression nuts on the valves. After cleaning the copper tube, slip the nut, compression ring and valve over the pipe and tighten them. Turn on the main water supply lines and check whether the valves and faucet are operating properly and are leak free. Finally, reassemble the garbage disposer, P-traps and drain lines to finish the process.
