RectorSeal redesigns its Clean Check extendable backwater valve product line’s upper and lower collars. It now accommodates both standard 4-in. diameter or optional easier-to-handle lightweight 2-in. diameter PVC risers for preventing sewer backups into light commercial buildings. The redesign also includes the new 75 psi-rated heavy-duty flapper.
