Waterway 2" bypass release valve

The Waterway 2" flapper valve body is primarily used as a pressure release mechanism on circuits with a a two-speed pump. The valve is typically plumbed on a bypass circuit, and opens when the water pressure rises.

It is often used between suction plumbing and a filter housing to prevent all the water flow from being drawn from the floor of the spa rather than through the filters. It is also helpful in a circuit with a 2-speed pump: When on high speed, it opens the valve to decrease the pressure in the water cricuit.

It connects to 2-inch pipes.
