Sioux Chief inbody

Sioux Chief’s new ProCheck backwater valve installs in both shallow and deep-bury plumbing applications. Due to its modular design, the ProCheck features many accessories for both 3” and 4” valves that are interchangeable, enabling contractors to buy and carry fewer items while still having the right parts. The valve lid, access sleeve, sleeve collar, sleeve lid and deep-bury adaptor kit all fit both 3” and 4” valves. ProCheck’s design also features an integrally molded sealing surface on the face of the flapper, which provides a better seal than typical O-rings.
