Waste-Pipework Joints

Joint Connection:
Place the large nut over the pipe. Follow this by the rubber ring or washer. If this is tapered, be sure that the taper goes against the fitting side. Finally, insert the pipe into the fitting and tighten the nut. These fittings are designed to be hand-tightened only. Do not use spanners or pipe grips. The rubber washer is relatively soft and can be perfectly adequately compressed with hand tightening. If the joint leaks, it is usually because one or the other component is out of line or misplaced, rather than the washer not being compressed enough and can be diagnosed and rectified professionally by a Harringay Plumber as a matter of course.

Plastic Waste-Pipework Compression Fittings.
These fittings work the same way as in the title. They use compression for grip, with rubber rings being compressed between the fitting and the pipework in a way that produces a watertight seal. Most of the plumbing fittings are now of the compression type since they allow for the pipework to be readily made and re-made. This means an easy way for any blockages to be sorted. A general arrangement is a fitting, trap or bend, with a large plastic nut at each end, and a rubber ring or washer at each end of the connection. These types of fitting are carried and used by professionals like Harringay Plumbers who can fit them fully guaranteed.

Cut Plastic Waste Pipework:
The fitting slips over the waste pipe up to a certain point. As you cut the pipework, make sure you allow for this extra bit to guarantee a watertight connection. The pipework once cut to length should have any burr taken off with a small file so the end is smooth. This detail is really important with the inner edge, because the wastewater that flows through could contain debris which quickly builds up and creates a blockage around the rough surface.
