You need to check the Schrader value with the tank empty of water and no
pressure on the water side (drain open).  With the tank empty of water
there still should be some pressure on the air side of the bladder,
can't remember the amount.  Reading with water in a failed tank a small
pocket of pressurized air.  This will cause the pump to cycle often and
hammer.
