The Mech 416 Access pipe is available in 50mm, 70mm, 100mm or 150mm.The purpose of this access pipe is to allow the soil or rainwater pipe system to be inspected and cleared in the event of any blockage.To use the access point, simply remove the access door by undoing the bolts. This could potentially release any blockage above the door so it is always advisable to stand aside at this point!Our Mech 416 access pipes are available with a choice of either round or rectangular access doors.As Mech 416 pipes and fittings have no sockets, couplers are required to connect this access pipe to a soil pipe or fitting.
