  • Secondly, you will cut off the water supply line that is running to the base of the unit and keep in mind that it is this place where you will be working. Now, cutting this line is easy as some fixtures contain a screw on connection and some comprise of soldered pipe.
  • Thirdly, you will have to slide the compression nut, which is linked to the shut-off valve onto the pipe where the threads are facing the open end. Next, just slide the compression ring.
  • Now, you will be wrapping the pipe with a Teflon tape or you can spread the plumbing joint on the end of the pipe. Afterwards, just push the shutoff valve on the end of the pipe and slide the compression nut. Besides, you also need to ring up to the shut-off valve and make the nut tight through hands.
  • In the next step, you will attach the compression fitting of the supply tube (which is flexible) onto the other side of the shut-off valve. Keep in mind that it needs to be hand tighten. Now, you will again attach the compression fitting to the supply tube in the base of the faucet and as usual, it needs to be hand tighten.
  • Since all the compression fittings are attached and hand tighten, you will use an adjustable wrench for tightening them firmly. Also, don’t over tight them as it can damage the compression fitting.
  • Finally, you will turn on the water supply and check whether there are any leaks or not.

With that said, it is inexpensive, but it work perfectly to ensure that your home is safe from the overflow of water. So, install them and enjoy a safe life!
