Our single socket drainage pipe is manufactured by UK leading supplier FloPlast, to BS EN 13476-2 SN8. Our pipes have a solid walled UPVC rather than the less robust foam cored versions available on the market.This single socket pipe comes with one socketed end incorporating a 110mm ring seal socket and one pre-chamfered plain end.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.This pipe is compatible with our soil and vent system and also with all other leading UK manufacturersand#039; drainage systems.Please note that orders for pipe only (without an appropriate amount of fittings) will incur an additional delivery charge, which we will contact you about before dispatching your order.
