- 1. A recirculating valve for use in a recirculating sand filter system, said recirculating valve being adapted to being located in a recirculating pump tank connected between a return line entering said recirculating pump tank and a discharge line exiting said recirculating pump tank, said recirculating valve comprising:
- a T-pipe consisting of a horizontal straight section and a downwardly directed branching arm having a large radius curvature allowing for smooth, nonturbulent flow of water into either said recirculating pump tank of water discharge line; and
- a float valve connected to said branching arm for blocking the flow of water into said recirculating pump tank when a level of water in the tank exceeds a predetermined maximum level thereby diverting water into said discharge line.
- 2. The recirculating sand filter system as recited in claim 1 wherein said recirculating valve is made of plastic and said float valve comprises a float housing comprising a large cylindrical lower portion containing a ball and a smaller upper portion containing a valve seat positioned vertically above said ball and cooperating with said ball to block the flow of water from said return line into said recirculating pump tank and instead diverting said flow of water to said discharge line.
