Clean Check® extendable backwater valves prevent sewage backup into a residence or building as a result of a plugged sewer system, excess volume in the system or groundwater flooding.
They are designed to be installed easily outside a home, business or other structure, without using a costly manhole, and are readily accessible for maintenance or cleaning.
The extendable valves consist of a tee-shaped valve body, a top collar and a bottom collar with a replaceable PVC flapper attached. In the event of back-pressure, the flapper blocks the reverse flow and prevents a sewage backup
