RectorSeal® Corp. announces the redesigned Clean Check® extendable backwater valve product line’s upper and lower collars, which now accommodate both standard four-inch-diameter (10.16-cm) or optional, easier-to-handle, lightweight two-inch-diameter (5.08-cm) PVC risers for preventing sewer back-ups into residential and light commercial buildings. The collar redesign includes the ‘snap-in/pull-out’ 75-psi-rated (at 177 feet of head) heavy-duty flapper, which can be installed and locked into the lower collar within seconds. This tight-sealing, plasticized PVC flapper is available for 3-, 4- and 6-inch-diameter (7.62-, 10.16- and 15.24-cm) sewer lines. Older style flapper/collar assemblies that are worn or 15-psi-rated can be retrofitted using the Clean Check Rebuild Kit, which includes the 75-psi flapper/collar and upper collar. Contractors must supply a new two-inch or four-inch-diameter PVC inner riser.The complete, patented Clean Check system is available in PVC or ABS plastic and consists of a tee-shaped valve body and an upper collar and matching lower collar. Available through US plumbing and heating trade wholesalers; sold as single units or three-packs. http://www.rectorseal.com, [email protected], (800) 231-3345
