Parks' Plumbing Flood Control System

Parks' Double Guard™ Flood Control System

Valves Assembly:

Parks' patented Double-Guard Flood Control System consists of two non-corroding red brass valves and seats encased in a cast iron housing. Red brass is an inert material estimated to last over 200 years. The two red brass valves stay in an upright, almost 'closed' position most of the time, and are opened only when waste water from the house flows through them. They completely seal closed automatically when the sewage from the overloaded city or village sewer main flows back toward the house. The valves work mechanically and automatically, they are not triggered by any electrical sensors and they do not need anyone to do something (like flip a switch) to tell them to close. When they close, they form a tight, 'brass-against-brass' seal, which stops sewage backing up from the overloaded city or village sewer main. The valves can be accessed by removing eight stainless steel bolts which then release two cast iron cover plates which are sealed with neoprene gaskets and attached to the main valve.

Compare our patented Double Guard Valve with any of our competitors, some use Styrofoam floats and cheap paper flappers!

A 6" cast iron overflow is also provided. It guides the waste water from the house into the pump basin when it rains and the system is in operation in the closed position. Also, during non-flooding conditions the overflow allows access to the house sewer line for rodding purposes.

The entire cast iron housing and valves assembly are inserted into the portion of the house sewer line, and then joined with the remainder of the existing sewer by using watertight neoprene mission couplings and stainless steel straps.
