Toro - Precision Check Valve (PCV-500)

Precision check valve (PCV-500) to stop low head drainage

Low head drainage shows up with an elevation change of under six inches, causing runoff, landscape erosion, unsafe conditions on hardscapes and sidewalks, and pooling around spray heads. The Toro Precision check valve seals the spray head at its connection point at the end of each cycle, so lateral lines do not drain through the lowest heads.
