Captive Air Water Tank

[Marcia Clarahan]

Can these things be recharged ? Seems ours has lost its air charge since the pump cycles for only about 10 seconds to bring the press ure from 45 to 55 psi. The tank is a 100 gallon size and is only 4 yrs old. There is a threaded port on top which looks like about the tire valve diameter. Any ideas ???Thanks Hans

Drained water and left valves open. Filling with air indicated bladder in the tank is ruptured since it could not be pressurized, To operate temporaarily I out a litle water in the tank and then pressurized to 25 psi. It functions with out the bladder but probably will have to be replaced. It is a Clayton Mark 1V and only 4 years old, probably no warranty left ?– Thanks for the help–Master Plumber !! Hans K
