Why is a balanced valve better than a cast iron check valve?
The Eveready Balanced Flood Control System was designed by an engineer who had a basement that flooded. He explored the possibilities of Overhead Sewers and Cast Iron Check Valves. In his investigation of the Overhead Sewers it was determined that extensive work would be necessary both inside the home, as well as outside of the building. After the Overhead Sewers are installed you will have eliminated the natural drainage of the building that now exists. Any seepage water from around and below the home would have to be mechanically pumped up to the Overhead Sewer. Your home now becomes more vulnerable to seepage problems you may have never experienced before. In the event of a pump failure due to either breakdown or loss of power, there is a possibility of seepage water accumulating in your basement. At that point in time his only alternative was a Cast Iron Check Valve. He was encouraged that the work could be installed on the outside of the building in one hole. He did, however, find
