I have a submersible pump in a domestic well and use a Square-D 40-60 pressure switch. I drained the tank and then installed a new switch and gauge but could not get the switch to cut in at 40psi and cut off at 60psi. It was more like 49/60. The water system turns on much more frequently than in the past and runs for a shorter time. I'm afraid of blowing out the pump with too many cut ins. I replaced the switch and gauge with new ones again, and got roughly the same readings. I fiddled around with it and could not get the cut-in below 49psi. So, I've installed 2 new pressure switches and 2 gauges and have a problem. I'd read somewhere that I could lower the cut-in to about 30psi while having the cut-off still be 60psi. I can't get the system to 40/60, much less 30/60. Any help in at least making a proper 40/60 setting would be fine. Setting it to 30/40 would be really fine. Looking forward to receiving a response.

My well is 10 years old. It is 581 ft deep and gets 1 1/2 gallons per minute. We have a non submerged pump. About 6 years after the well was dug we began to get black flecks and muddy looking water. A camera was ran down the well and we were told that a flange type pvc pipe would need to be added to the inside of the old pipe. They put in the pipe and poured cement between the old pipe and the new one. The water cleared up, but now 4 years later, we have a similar issue extremly red muddy water. What could be causing this issue and how can I fix it. Thanks for suggestions:
