Cutting Plastic Pipes:Plastic pipework can be connected to other pipework and therefore needs to be cut. The pipe should be supported well and marked either with a pencil or you could use paper that is wrapped around the pipe using the paper edge as the guide. Once the cutting has been done, you should clear any burrs and particular importance should be paid to the inner edge, as the waste-water that flows through could contain foreign material which can build up around a rough surface and block the pipe. These fittings are used by professionals such as Vaillant Boiler Repairs London.Sealing Plastic Pipes:Compression fittings work as the name suggests 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. Vaillant Boiler Repair London are experienced with compression fittings.Connecting a Plastic Pipe to a Trap:The usual arrangement in a waste system is a trap or bend, with a large plastic nut at each end, with a rubber ring or washer for both ends of the connection. Put 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, no tools! 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.
