Frequently Asked Questions

What is cross-linking PEX tubing?

The PEX tubing undergoes a cross-linking process which enhances the material's properties, making it resistant to heat, pressure and chemical degradation.

How to connect / disconnect a ProLock fitting to a pipe?

  • Cut the pipe using a copper pipe cutter. Remove all burrs and sharp edges.
  • Insert the pipe fully into the fitting.
  • Turn the locking cap clockwise (in 90 degrees) to lock the position. The correct position can be determined by the audible click and the indicator marks.
  • To disconnect, depressurise the system and turn the locking cap quarter turn in an anti-clockwise direction. Now, depress the collet against the fitting and remove the pipe.

What is the use of water supply stops?

Water supply stops, also known as shut-off valves are devices used to control the flow of water. They include a handle that is used to control the flow of water or isolate the supply to a specific zone. These stops are commonly made of acetal, brass or stainless steel.
