Well pressure question
"Keith" #ca wrote in message ... Hi all, I have an in-well pump with a solenoid and expansion tank where the line enters the house. Can someone please advise what the air pressure should be in the tank? I had thought it was to be 28 or 29 lbs and put this when the line was depressurized. Upon opening the line, the pressure of course went up to 60 or 70 lbs with the pressure of the water on it. I thought this was OK but a neighbour said it was way too high. So, what is the proper procedure to do this and how much pressure should I put in the bladder? Also, what are the proper settings for the high (cut-off) and low (cut-in) pressures? Thanks Keith You must have a 40/60 so 38 But reading your other post hope you have a safety relief valve these pop about 75 psi far below a water heater TPR valve Spud A stuck pressure vavle |

Well pressure question
Hi all,
I have an in-well pump with a solenoid and expansion tank where the line enters the house. Can someone please advise what the air pressure should be in the tank? I had thought it was to be 28 or 29 lbs and put this when the line was depressurized. Upon opening the line, the pressure of course went up to 60 or 70 lbs with the pressure of the water on it. I thought this was OK but a neighbour said it was way too high. So, what is the proper procedure to do this and how much pressure should I put in the bladder? Also, what are the proper settings for the high (cut-off) and low (cut-in) pressures? Thanks Keith |

Well pressure question
pump/impeller and installation design determines the cut in and cut off
pressures. adjust pressure of the air bladder to 2 lbs below cut-in with water pressures/suction in the tank or and no hot sun beating on it... anotherwords kill pump power and open a faucet check and adjust pressure.

Thanks Keith The pre-charge is adjusted with the tank empty (turn off pump and open a valve) and is set to approximately 2 psi below your cut-in pressure. Standard pressures for residentual systems 20/40 - adequate but minimal and not very satisfactory at the low end. 30/50 - good. Some impulse sprinklers might have a problem at the low end. 40/60 - very good but not really needed unless doing a lot of irrigation. Some people like this because of the 'hard, needle shower' at all ranges. Setting over 40/60 are not recommended as they cause excess wear on fixtures. The pressure switch should have instructions on how to adjust it. Usually one screw taller than the others will adjust both the cut in/out settings while the others adjust just one of them. Harry K |

Thanks Everyone
Thanks to Bumtracks, Harry K, and Spud for taking the time to respond.
Set it up yesterday and tap pressure is now much better than it was. Keith |
