Step by Step: How to Install an Outside Faucet With PEX Piping

How to install an outside faucet with PEX piping

Here are the steps that you should follow to install an outside faucet with PEX piping.

Step 1: Shut off the Water Supply

  • First and foremost step, you should do is to shut off the water supply.
  • You may either switch off the water supply to the specific pipe where you will be working or turn off the main water valve to your residence.
  • Remember that it will block the water supply to your whole house, until it is turned on.
  • Let’s go to the next step.

Step 2: Drill to Mount the Faucet

  • To install the outside faucet, start by drilling a hole in the basement wall at the spot where you want it to be.
  • The hole has to be 1 inch in diameter in order for the sillcock faucet to fit through it properly.
  • Insert the sillcock faucet into the opening on the outer wall.
  • After inserting, take some galvanized screws to secure it to the wall on both sides.
  • Inspect the faucet to ensure that it is oriented downward toward the interior of the home.
  • This added approach will help to protect the water from freezing in the wintertime.
  • Tip: A silicone sealant should be used to secure the connection.

Step 3:Connect PEX Adapter

  • Make your way to the interior of the home to locate the other end of the sillcock faucet that you just completed installation of.
  • Then, using a copper cutter, trim the water pipe from where you’d like to make the connection.
  • Ensure a bucket is positioned beneath the sink since any water that accumulates in the pipelines may drain into it without causing a mess on the floor.
  • Now, you have to mount the threaded tee at the place, where you have created the cut and connect the pex adapter to the free end of the threaded tee.
  • Weld all of the new joints to the water pipe together using a soldering iron to keep them in place.
  • Remove any remaining remnants with a cloth.

Step 4: Connect the PEX Adapter

  • Retrace your steps back towards the end of the sillcock faucet that is located inside the home.
  • Wash the end from the inside to ensure that nothing is obstructing the water’s flow route to the outside.
  • This would be completed with the help of a cleaning brush.
  • The PEX adapter should be oiled. once you have oiled the adapter, mount it to one end of a new water cutoff valve.
  • After that, you must connect the cutoff valve to the tip of the faucet, with a copper fitting somewhere between, to complete the installation.
  • Before connecting the pieces, lubricate all of the ends.
  • All of the new connections should be secured in place with the help of a soldering iron as well as some soldering wire.
  • Remove any solder dust from the connections by wiping them with a cloth.
  • Now, leave the connection to rest before fitting the PEX pipe.
  • This is due to the fact that it is made of plastic and may melt.

Step 5: Install the PEX Pipe

  • Attach your PEX pipe into the free end of the connection you created between the water pipe within the home .
  • Now, you have to position it in a PEX clamp and twist it to ensure that the connection is secure.
  • Extend the PEX pipe above the ceiling of your basement.
  • You should also fasten it with 1-inch PEX clips at appropriate intervals throughout the length of the PEX pipe.
  • Take the PEX pipe all the way around to the inside of the faucet, attaching it at the top all the way down the length.
  • Trim the PEX pipe using a PEX cutter at the place where you want to establish a connection to the faucet.
  • With the help of an expansion tool, attach it to a PEX adapter at the other extremity of the faucet.
  • Make use of a PEX clamp to secure the connection in the same manner as you performed at the other side.

Step 6: Turn on the Water

  • Now you have to check that your outdoor faucet is working or not.
  • For that, you have to turn on the water supply line to your home.
  • Open the Main water valve that supplies water to your whole home or just the water pipe you were working with.
  • Turn on the cutoff valve that you put on the inner end of the faucet as well.
  • Step outside and turn on the outside faucet.

That’s all, you have successfully completed this job.
