We have a well Meyer pump and H2Ow-to pressurized water tank.. We hardly have water pressure and when we do it's not for too long. Sometimes when you flush the toilet or turn on a faucet it sounds like water in the lines and then when it does kick sometimes it will blow out some sediment. The pump kicks on at about 12 and shuts off at about 30. We have 2 inch well.. Please help us troubleshoot.. Thank you

Assume a surface pump, what kind, what HP, how deep is well?
What kind of tank, pressure tank or bladder tank, how big.

Cut in pressure is way to low. Most people prefer a 30/50 or a 40/60 cut on/cut off setting.
