Square D with lever, has 2 posts for adjustment, the center proudest stud for Range"turn nut down for higher cut-in, or up for lower cut-in. I thought this one is for raising overall pressure??
lower stud off to side is Differential "turn nut down for higher cut-out pressure or up(loosen) for lower cut-out-so this one is used for overall higher pressure?
I can't seem to get the pump to come on later-say when she goes down to 30psi? I turned pump off and drained, when gauge hits BAM! switch clicks and gauge drops to 0.
The big spring (proudest) if tightened, will increase both the kick-in and the kick-out. The small spring if tightened, will increase only the kick-out.
well I currently have it at 34-35 kick-in and 52 kick-out using trial/error since logic doesn't seem to work? sure would like to get the spread further apart...wish it were that easy!
I would love to see it in operation at say 30-55...
Tightening on the small adjustment screw will widen the bandwidth between on and off. But why do you want to do this??
well I adj.the tank psi to 28 per a 30/50 sw. and would like to at least try the 30 cut-in....then an extra 5 for the heck of it.
I just can't seem to ever get that cut-in below 34?
Then loosen on the big screw to lower the cut in pressure. (one round = 3 PSI) Most people want an extra 5 or 10 pounds "for the heck of it" to try and get a little extra run time. All you are doing is overstretching the bladder and shortening the tanks life. When I go to a pump system where someone has widened the bandwidth, I know they are trying to reduce the cycling.
I'll go try it again with pump on, it's almost like I could take the nut right off of the range/main stud, once the gauge drops to 34 it clicks and water drain just immediately stops too
You can keep the 20 PSI spread and increase the cycle time a little by increasing the pressure. GPM from the pump generally diminishes with pressure so at 20-40, the GPM will be more than at 60-80. The GPM through the fixtures however increase with pressure, so your showerhead will put out more GPM at 60-80 than at 20-40. The two combined will result in the pump cycling less during a shower.
I loosened large/range adjuster 3 twists of ratchet(a tad over 1 full turn) no change. I then loosened it another 3 twists, no change?
I noticed when draining gauge gets to 35 and 3 things happen, gauge drops to 0, cut-in clicks and drain is empty(and closed by me at that point) then gauge slowly begins ascending then at 20 it jumps to 40 and pumping begins? Goes to 51psi and stops
If the pressure drops really fast from 35 to 0, it probably means that the precharge on the tank is too high and that at 35, there is no more water in the tank.
As for how the pump surges from 20 to 40, again if the bladder precharge is too high, there is nowhere for the pressure to go until it exceeds the precharge. Also, the pump uses pressure to make pressure so you will notice a performance curve.
