WaStop® Inline Check valve
In 2013, a packaged residential WaStop unit was installed in a private home in an area where previous floods had caused more than $4,000 of damage to basements each time flooding occurred. Since the Wapro Access unit was installed, there have been no more flooded basements.
Design: Wapro Access Chamber with a WaStop module. Note the 8' extension tube installed as a riser from the Wapro Access Chamber.
