Cut in @ 30 PSI is ideal, but I do not want to raise the Cut off PSI anymore which is what happens when I turn down the big spring. by qualified electrical And high water pressure that exceeds the rated water tank pressure can burst the tank - a very dangerous event. The larger nut (green arrow) on the larger spring in the pump pressure switch: changes cut-in AND cut-out simultaneously moving them both up (higher pressure) or down (lower pressure). Check the pressure switch to see at what pressure this occurs. this material. That was zero. If the pump is turning on at just under 50 psi that sounds considerably too high to me; Normal cut-in is either 20 psi on a 20/40 switch or 30 psi on a 30/50 switch from the factory.The tank pre-charge air pressure - with the pump off and all pressure relieved at a water tap - would be around 2 psi below the cut-in pressure. Put another way, many homes that operate between 30 and 50 psi have very good water pressure and flow rate at the fixtures. If you have a one-post pressure switch, turn the nut clockwise to increase the cut-off and cut-on pressure. In your case, your holding tank seems to have a separate feature (low level float switch) which turns off power to the switch.

That said, here are some things to consider: Most pump pressure controls are tricky to adjust in the way you mentioned, but you should be able to set the cut-in to a higher number and then adjust the cut-in - cut-out pressure differential to keep the cut-out pressure from being too high. Or in a contrary case if you completely loosen the smaller nut #2 (differential adjustment) - as we see in Moby's photo above, the pump differential between cut-in pressure and cut-out pressure is very small the water pump may short cycle on and off rapidly when water is being run in the building. Here are the top 10 reasons you should love writing blog posts. 8001 Knightdale Boulevard The drop in pressure may occur if you attempt to use a greater volume of water than either the well or well pump can produce. It has the practical effect of raising or lowering the operating pressure range of the switch. Recently we had our pipes freeze and this problem occurred after removing the ice and it took 3 days to get the pump up and running again. Some pressure control switches have only the range adjustment nut and no differential nut. 3) When I drain the tank to perform a pressure check, I get little if any water from the tank, which would explain why my cycle sucks.
