This check valve is used for screwing in between the water filter and the water hose in the irrigation system with a fitting connecting piece, 2,54cm (1"). It warrants that no water runs back to the pump and to buoy up the pressure in the hose.
If the water hose drains every time, the anterior drip pricker would start earlier to drip than the posterior.
