Check Valve and Threaded Nipple (for Pressure Systems and Long Runs)
RPS Solar Pumps - ACC
Check valves allow water to pump up and out of your well, but not back flow. While a check valve is optional for RPS systems when pumping into the top of a storage or stock tank, when pumping into a tank bulkhead at the bottom or into a pressure/bladder tank, a check valve is needed. Your kit will come with a threaded barb of the proper size for your pump and it will fit the check valve of the same size as they are all NPT thread. Use thread tape on screw connections. No lead Stainless spring check.
