The decision was taken to fit a 1.5m WaStop with a custom flange plate to form a tight seal to the existing civil structure. The 1.5m valve supplied for this site is the largest WaStop check valve to be installed in the UK and one of the largest to be installed in the world.
WaStop Residential RangeWapro’s complete range of backflow protection products for residential use provides protection against backflow flooding and gives peace of mind. With WaStop non-return check valve available in two variations and the WaBack Residential chamber complete protection against sewer backflow can be provided for homes and other buildings.
WASTOP PUSHFIT DN110 (4”)
WaStop PushFit protects homes and properties by allowing flow only out of the sewer line and prevents sewer backflow. Sewer backflow occurs in combined sewers when heavy rainfall events occur which overload the sewer system. Sewerage then finds an opening to release the pressure in the pipe. This point is often a toilet or hand basin in the lower levels of a home. With a WaStop PushFit installed outside your home the sewerage is stopped from entering the home and therefore effectively preventing damage to your home.
WASTOP RESIDENTIAL DN110 (4”)
WaStop® Residential (RSD) stops backflow in sanitary sewer laterals. WaStop RSD should be installed in an accessible point either inside the house or just outside. Installation is done by removing a section of pipe equal length to the WaStop and attaching the WaStop to the existing pipe with flexible couplings. Care should be taken to ensure the valve is installed right-side-up and should be visually inspected twice per year.
WABACK RESIDENTIAL DN110 (4”)
WaBack Residential is an all-in-one installation with a chamber for inspection purposes and an in-built automatic check valve. Designed for keeping properties safe from sewer backflow and dry during heavy rainfall events.
WaBack Residential is designed to be used in heavily polluted water and can, therefore, be used in sewer applications. WaBack has a completely open flow area for sewer pipes with minimal grade.
