WaStop® Inline Check valve
Installing a check valve in the upstream chamber would not have been an optimal solution considering the design of the chamber. Nor would installing a check valve at the outfall of the pipe have been a good solution since the end of the outlet lies underwater.
Instead, Wapro’s technical salespersons and engineers designed a customized solution together with the client. By removing the crown of the concrete pipe, it was possible to install a WaStop DN1200 with a half flange on the inlet side of the valve by bolting it inside the concrete pipe. With a unique pulsating flow mechanism every time the membrane is opened, the WaStop check valve minimises the risk of anything getting stuck between the membrane and the pipe. The end result is an effectively sealed check valve that will prevent backflow for many years.Go to product
