Plumbing with Push Fit Fittings

Tools required :- Marker pen and pipe cutter.

Push fit fittings are one of the better inventions to come on the DIY market in recent years, the time they save on plumbing installs or repairs is invaluable. You don’t need a blowlamp which takes away the risk of fire or burns, and they can be fitted with just a few hand-tools.

They are available in plastic, copper and chrome finishes and a wide range of sizes, offsets and connections to suit most plumbing DIY jobs around the home.

Inside the push fit fitting there is a rubber ‘O’ ring which creates the seal around the pipe, because of this I would advise using a pipe cutter (which are very easy to use) rather than a junior hacksaw to cut the pipe to length as hacksaws leave burrs around the edge of the pipe. Read the instructions that come with the fitting so you are aware of any additional features it may have, i.e. twistlock.

Using the push fit fitting.

  • Mark the pipe with a pen so you have a reference mark to show the when the pipe is fully inserted, as in the photo below.

Once the pipe is inserted fully into the fitting, if the fitting has a twistlock feature (as the one in the photo does) twist it until it tightens up on the pipe, this is usually only a 1/4 to 1/2 a turn. Check the collar is in the out position and then pull on the pipe and fitting to ensure it is secure, see the photo below.

To release the pipe from the fitting, unlock the twistlock then push in the collar and pull the pipe and fitting apart.
