All types of plastic pipework can be joined to other types and therefore will have to be cut. Before you cut the pipe it should be well supported and marked with a pencil or you could even use paper that is wrapped around the pipe using the paper edge as a guide. Once the pipe has been cut, you will need to remove any burrs with particular attention being paid to the inner edge, because any waste-water flowing through the pipework may carry foreign material which eventually builds up around rough surfaces and can cause a blockage. These types of fittings are always used by professionals like Woolwich Plumbers. To Seal Plastic Pipework you can use compression fittings as they work really well with this kind of material. The tight waterproof seal is created by compressing two rubber rings between the pipework and fitting. Standard plumbing fittings are now of the compression type since they allow the job to be assembled and also taken apart really easily, which can clear a blockage quickly. A Woolwich Plumber is experienced with compression fittings. To Connect a Plastic Pipe to a Trap in a waste system for example is done by using a large plastic nut at each end, and a rubber ring or washer for both ends of the connection. Place the large nut over the pipe. Next the rubber ring or washer. If this has a taper, fit it so the taper goes to the fitting side. Lastly, insert the pipe in the fitting and tighten the nut. Hand tighten only, as the rubber washer is quite soft and can be adequately squeezed by hand. If a joint is leaking, it usually means one or other component is misaligned or misplaced, rather than the washer not being compressed enough. As you can see, the plastic pipe is a real asset to any plumber or amateur DIY’er.
