Released in the early 1970's, this check valve has been installed in millions of homes throughout the United States. The innovation is in the adapters, which accept both 1-1/4" and 1-1/2" pipe and in the valve body itself, which is designed for quiet operation.
Released in 1980, this sump basin changed the industry. For the first time, a basin was being made using an injection molding process that combines gas and resin into a finished product that is made of what is called structural foam. This innovative basin is lighter, stronger and less expensive than previous basins made of cast iron or fiberglass.
