my well wont build pressure

at first i lost all water to my house. so i did some checking around and found the foot valves get clogged. so i pulled up the pipe and cleaned the valve. then it was a pain to get the well primed. now it will not build any pressure nor shut off intil i put air in the tank. then when it goes below 25 psi it will turn on but wont build any pressure. can you please help im tired of staing at my mother-in-laws house..

thanks
joe

Do you have a shallow well or deep well jet pump. It sounds like the jet assembly is plugged and needs to be cleaned out.
