110mm Wastop

£820.00 + VAT

110mm Wastop valves are inline backflow and flood prevention valves. WaStop inline non return valves (NRV) are made up of 316 stainless steel incorporating a cone-shaped chloroprene membrane. The membrane allows flow to pass in the desired direction but when backflow occurs the membrane fills out and seals the pipe.

For foul or combined sewer applications we would recommend using our SSL 110
