Ok forgive me for silly questions....I`m a newbie to wells and pumps, ok my problem....my pump is short cycling, I drained the pressure tank to zero,checked air pressure with tire gauge, no pressure , pumped it back up to 28psi(should the gauge on the pump be showing this pressure also?)turned pump back on built system pressure to 50psi...all was well for 3days,short cycling again drained tank used tire gauge..no pressure at the shrader valve again , so I have once again pumped up the bladder , my pressure tank is just under 2 years old a Well-x-trol WX202Pro....any ideas?
