The pressure rating of the check valve should exceed the maximum output pressure of the pump. 3 (2005): 14-16. If the leaky check valve is the foot valve in the well you'll face the more troublesome task of opening the well and pulling up the well line and foot valve. Another easy option is installing a couple of stop valves, a bypass line, and then installing the a check valve facing in or permitting flow in the desired direction in each of the two water line passages.

One other random question - do you know what is the typical useful life for the ball-type shutoff valves shown in the picture? Engineering data, including available materials, dimensions, exploded view, part numbers and descriptions, standard models, valve Cv, pressure loss curves, and other information is available in our brochures. Match it as close as possible to the pipe diameter. If the air valve itself is not damaged, perhaps that's the trouble. BUT, if I DID loose prime for some reason, would not the top check valve have to be removed to allow me to prime the pump? A check valve at this location is a great idea and reduces the risk that a failure I'd start by checking right at the pump to see if it's delivering water or not.

I really appreciate this site being here and have referenced it many times. - a well and pump system that seemed to be just fine and seemed never to lose prime, until we left power off to the pump for a few days. This can cause the pump to rotate in the wrong direction as the water returns to the source. A leaky foot valve slowly leaked all of the water backwards into the well from the pressure tank and jet pump, losing pump prime in the process.
