Installing A Cap

There are two types of capping methods when it comes to capping your PVC pipes.

If you are doing it permanently, you will need to cement the cap in place.

How To Install A Rubber Cap

If you wish to install a rubber cap, follow these steps below:

  1. Turn off the water supply and allow residual water to drain. Make sure to do this before unscrewing any pipes.
  2. Measure and cut the pipe to your chosen length. Cut the area with a hacksaw, and then clean the end with a cloth. You might need to sand down the area if the edge isn’t smooth.
  3. Now comes the easiest part! Simply put the cap on top of the exposed pipe and press it down. Make sure to push it down far enough so that it is stable. Then fit the stainless steel clamp and tighten it to seal the rubber cap onto the PVC pipe.
  4. Once the cap is applied, fit the pipes back into position and turn on the water supply. If there is a leak, you’ll need to put more pressure on the cap and stainless steel clamp.
