| Parks' Double Guard Flood Control System - BWV | |
|
Our Double Guard Flood Control System is our number one specialty and product. It is installed on the house sanitary sewer line and consists partly
of two brass flappers (encased in a cast iron body) that open and close, thus allowing sewage and waste water to flow from the house to the
street, but not allowing sewage and waste water to backflow from the municipal sewer lines toward the house. The flappers are fully
automatic and activate mechanically just by water flow. Also, we put in a cast iron overflow, and a pump basin where an ejector pump is installed. The purpose of the ejector pump is to discharge any waste water that comes of the house when the municipal sewer lines are backing up and the two flappers are closed. The ejector pump then discharges the house waste water through a 2 inch copper piping and a inline check valve on the "outside" of the two brass flappers. Please contact us for a free in-home presentation and estimate if you would like to have our Double Guard Flood Control System installed. Our Double Guard Flood Control installation was recently featured on an episode of Ask This Old House. |
