Plastic Pipes and Push-Fit Connection


Pipes:
These are flexible and easy to work with. This flexibility is a real bonus for installations as it can reduce the number of fittings required. When feeding a pipe, tape over the end or fit a dust cap to prevent debris getting into the pipe and to protect the end from damage. Plastic pipe is various diameters ranging from 10mm to 28mm and lengths of 3mtrs and 6mtrs or on a roll of 25mtrs or 50mtrs. Plastic pipework may be used on hot and cold water systems but it is not suitable for central heating. A special barrier pipe is made for this purpose.

When cutting, always allow for the amount of pipework that will sit inside the fitting. On Hep 2O pipe this is the distance between the ‘V’ marks. The cutter blade should be aligned with the next ‘V’ mark on the pipe and pressure applied to the jaws. Rotating the pipe as you apply pressure will result in smooth square cuts. Clean off any burrs. Mill Hill Plumbers cut and fit pipework.

Push Fit:
These fittings are simple to use and there is a wide range available. Most of the fittings are available. Inside each connection, there is an ‘O’ ring seal and a specially designed grab ring. On no account put your finger inside one of these fittings the grab rings are very sharp.

Connection:
Put a pipe insert into the end of the pipe before assembly. The insert will help to keep the pipe rigid where it enters the fitting. With the insert in place, push the end of the pipe fully in. If you have used the ‘V’ mark when cutting, the pipe will be fully engaged when the next ‘V’ lines up with the cap. Pull on the pipe to make sure the toothed grab ring has fully engaged to secure the pipe. Dismantling fittings is a straightforward job but you will need specially designed keys for this.
