Houston — RectorSeal Corp., a leading plumbing and HVAC/R product manufacturer based in Houston, recently redesigned its Clean Check extendable backwater valve product line's upper and lower collars. They now now accommodate both standard 4-inch-diameter or optional easier-to-handle lightweight 2-inch-diameter PVC risers for preventing sewer back-ups into residential and light commercial buildings.
The collar redesign also includes the 75-PSI rated (at 177 feet of head) heavy-duty flapper, the highest flapper PSI in the plumbing, waste water, and sewer industries.
The new patented "snap-in/pull-out" flapper can be installed and locked into the lower collar within seconds. The flapper/collar assembly, riser, and upper collar are easily lowered into place and locked into the valve body and outer riser's slot channel with just a quick counter-clockwise, quarter-turn from ground level — making it the industry's easiest, safest to clean, and install extendable backwater valve.
The tight-sealing, plasticized PVC flapper is available for 3, 4, and 6-inch-diameter sewer lines.
Older style flapper/collar assemblies that are worn or 15 PSI-rated can be retrofitted within minutes using the Clean Check Rebuild Kit, which includes the 75-PSI flapper/collar and upper collar. Contractors must supply a new 2-inch or 4-inch-diameter PVC inner riser.
The patented Clean Check, which prevents sewer backup into buildings caused by blockages, excess volume in a sewer system, or ground flooding, is an IAPMO/UPC code-compliant above-ground cleaning access port that supplants the need of expensive manhole sewer-access cleanout vaults.
The complete Clean Check system is available in PVC or ABS plastic and consists of the following components:
• A tee-shaped valve body for connecting to an underground sewer line.
• An upper collar and a matching lower collar with a snap-in integrated flapper assembly that fits into the tee's bull via a contractor-supplied custom-cut-length PVC inner-riser pipe (contractors also provide a 6-inch-diameter PVC outer riser for 3- or 4-inch-diameter valve bodies and an 8-inch-diameter outer riser for 6-inch-diameter valve bodies).
Clean Check is available through U.S. plumbing and heating trade wholesalers and is sold as single units or three-packs.
