Our plain ended drainage pipe is manufactured by leading UK supplier FloPlast, to BS EN 1401-1. Our pipes have a solid walled UPVC rather than the less robust foam cored versions available on the market.This plain ended pipe comes with pre-chamfered ends ready for insertion into a ring seal.When cutting pipes it is good practise to always chamfer the ends with a rasp or file prior to inserting into any fittings. SG100 Lubricant should be used whenever a joint is made. Pipes should generally be laid to a fall of 1:40 in drainage systems where there are less than five WCand#039;s discharging into the pipe.
