I have a shallow well jet pump with approx 100' of 1-1/4" feed, with foot valve at the well end. I fired it up and got good prime - but could not hold 40 lb pressure (pump hit 40, kicked off, so far so good, then the gauge slowly dropped off)
I discovered a bad coupling in the line (which I replaced and I think I've fixed - will test when everything is bolted back together)
Question - since I'm into this project now, would it be a good idea to add a check valve on the intake line a couple feet from the pump (in addition to the existing foot valve out in the well)? Thinking this might take the pressure / strain off the foot valve (and the rest of the line - e.g. other couplings) - and save me some grief / digging later on? Or will this backfire on me by preventing the foot valve from closing properly, or some other problem I didn't think of? Is this generally a good or bad idea?
Any feedback appreciated - thanks...
