Welcome to the Williams Press-fit Page!


Why Press?

Press-fit pipe systems used to be the preserve of the commercial and industrial installer, but is now the fastest growing pipework system in the domestic plumbing sector, with sales of guns and fittings doubling every 18 months or so.

Why are so many domestic plumbing and heating engineers making the switch, and what do you need to know if you are contemplating joining them?

This page aims to show you at a glance the main considerations of using Press-fit, the Williams Press-fit product range and our options for either purchase or hire purchase through Williams.


Why choose Press-fit over soldered copper or plastic Push-fit?

 Press-fit vs soldered copper:

  • No heat or flame required – doesn’t activate fire alarms, damage paintwork, or cause fires in attics.
  • Joints can be made even if there is residual water in the pipework
  • No flux or solder residue or fumes – either in the pipework or in your lungs. 
  • Very quick to make a joint – just a few seconds. Does not require time to cool and no flushing is required.
  • No snots or flux discolouration.
  • Leak path technology – fittings that have not been pressed will visibly leak, unlike endfeed fittings which can appear to be watertight even if not soldered.

 Press-fit vs plastic push-fit:

  • Fittings are much less bulky and the finished job looks more professional
  • Fittings are cheaper and rodent proof.
  • Makes a solid connection, pipe will not twist in the fitting.
  • Fitting will not accidentally dismount.
  • Can be used with gas as well as water (subject to using the correct fitting)
  • Maintains electrical continuity for earthing.
