Campbell Brady 1-1/4 in. D X 1-1/4 in. D FPT Plastic Threaded Check Valve

Easily and efficiently allows the washing down or jetting of Brady well screens for shallow irrigation wells. Wash down valves attach to any 1-1/4 inch or 2 inch well screen or casing. Internal female threads allow for easy 1-step wash-down when attached to any source of water pressure (usually a garden hose). When water pressure is removed, after you have washed to desired depth, the internal valve seals off the bottom to prevent sand from entering.
