How to Replace a Single Handle Kitchen Faucet?

Let’s see how you can change the single-handle faucet yourself in the kitchen. The following points will be easy to follow;

  • The first step is to switch off the water line valves that are mostly under the kitchen sink. Close them up before you start any work. Now twist the faucet open to drain the remaining water.You can use a wrench to remove the hot and cold water lines.
  • By using a wrench, you should now open the screws behind the faucet and further remove the sprayer hose. First, lift the sprayer hose and then remove the faucet. Clean any debris that must have come out while removing the faucet. If the cap of the sprayer hose is okay, let it stay on and don’t remove it. 
  • Now attach the new hose through the hole and the faucet. To do this, use a wrench to connect it to the hose and that to the sprayer.
  • You can purchase flexible connectors to keep the hold, and cold water supply lines separate. The adapter will be connected before you connect the faucet to the sprayer hose.
  • Insert connectors and supply lines through the centre hole among the three holes and then place the faucet over it.
  • Install a plastic nut and washer under the sink that will keep the faucet in its place. Tighten them using a wrench.
  • Now you must connect the second connector to the connector’s male ends and the shutoff valves. Tighten them well and switch on the water to check for leaks.

This can be fairly easy if you keep following the steps but go to a plumber if it gets complicated.

How to Replace a Single Handle Bathroom Faucet?

Let us see a step-by-step guide on how to replace a faucet by oneself.

  • Understand the faucet that is already installed in your bathroom. If it’s a single-hole faucet, the faucet doesn’t only serve as a spout but a mixer of hot and cold water valves as well.
  • Collect the important parts after you have decided on a single-handle spout of the faucet. Always check before what was already installed and buy something similar to it. Now you can shut water valves off to prevent any accident.
  • After it is turned off, twist the faucet open to drain out any remaining water. You must now remove a flexible extension that is attached to the faucet by using a wrench. And after that, separate the same line from the valve that is for shutting off the water.
  • Now, if you look under the sink, some nuts secure the faucet in place. Unscrew them using a wrench and lift them from the top. You can use a lubricant if it feels stuck.
  • By following the instruction of the new faucet, install it with its spout and bouse. Fix them up with a wrench and do check for leaks before you open the main water lines.

Finally, you’re done replacing the single handle or spout faucet in your bathroom.

How to Replace a Single Handle Shower Faucet?

Let’s see how we can replace the old shower faucet with a new one in the following steps:

  • Locate the water for the shower and shut it off. Place a bucket under the spout to capture any excess water from the faucet.
  • Now, remove the plate and the faucet handle to see the shower valve.
  • There must be locking nuts that need to open up by pliers and then remove the old cartridges by pulling them out.
  • Now that the centre of the valve is empty insert a rubber seat with spring and put it in the valve. Repeat it for other seats.
  • Now put the new cartridge in the valve.
  • Put the O ring onto the cartridge and tighten them by using pliers.
  • Take the new faucet plate and place and cover the valve and tighten it in place with the screws given with it.
  • Now you can attach the newly bought faucet handle. Turn the water on to check for any drippings or leaks.
  • You can also arrange for a temperature limit fixture that will stop the temperature from going more than 120 degrees F and therefore prevent scalding. 

How to Replace a Single Handle Bathtub Faucet?

Bathtubs and showers have different spout handles and therefore should not be confused as being the same. Let’s see how you can change a bathtub’s single handle faucet in the following steps:

  • Start by closing the water valves, and if you cannot locate the separate water valve for the bathtub, close the main water supply. Now you can open the handle and let out any remaining water in the faucet handle.
  • Now you must remove all that is attached to and around a faucet. It includes the escutcheon plates, tub spouts, handles plates, the handles themselves with the help of pliers or screwdrivers. You can remove the spout by using a plier but make sure not to scratch it.
  • Tub walls have an access panel that must be removed to reach the pipes and valves. If you cannot find it in the bathroom, look in the room next to it.
  • You can outline the panel with a pencil since it covers holes left by the faucet handle. Drill ¼ down the line you made and created a hole. 
  • Cut pipes that are connected to valves that are already there. Use a pipe wrench and unscrew any unions’ nuts that are present there on the pipes. 
  • Get adapters if you need hot and cold water lines and attach them to the new single handle valve. If the pipes are plastic, then get a plastic adapter. Secure the connection by using pipe tapes.
  • Now put the valves in place by using the plumber’s tape, which is held in their position with the help of screws. Now that the valve is attached to the frame connect hot and cold water lines using a wrench.
  • Now put the new spout into place that may have come in hand with the new handle faucet on the same place where the old spout was.
  • Now you can place the faucet trim. Now slide the wall panels that you removed and secure them in place with anchor screws and then attach the handle and plates, respectively. If you didn’t have to drill in the wall, place the plate and screw the faucet handle in place and cover any holes you see after placing the single handle faucet. 
  • Now use silicone caulk to permanently stick the spout’s base, the plate of the faucet, and a conversion plate. You’re done.
