Okay. Live in Pa. Have a dug well. 18ft deep. A few days ago, the top portion of ground collapsed around the top casement and allowed mud into the well (Due to spring thaw and 5 days of constand pouring rain). Due to that, the foot valve was stuck in about 8 inches of mud and gravel. Had no water pressure. Brother came over with the backhoe and we dug it up last friday. Come to find out, I had a small hole in the water line about 8 ft from the well going to the house backdraining water around the well which is why it collapsed. So replaced the water line, replaced the pump, replaced foot valve. Everything from the pump to the well is brand new. Primed the pump yesterday and had great pressure for about 5 hours. Was taking a shower last night and slowy the pressure went from good to just a trickle. Checked all other faucets and water points, no pressure. Went to the pump, it's sitting at 40psi (30/50 Pressure Switch), Pressure at the pressure tank is the same (40psi). Pressure tank seems to be half full of water as well. So turned the pump off, it's full of water. Pressure in tank seems okay? Now I have no idea where to check from here? Also have an inline whole house filter after pressure tank. New filter as of saturday. Where to turn? Not sure if my pressure tank has a bladder or not. Has a date code of 1994 (it's a well-trol 30 gallon). Thanks in advance.
