Hello,

Depending on the type you have, the internal pressure relief valves have trash in them or have blown the seals in them.

I would remove the cylinder and have it gone through completely to clean out debris and replace all the seals.

catmastertech has been spot on and I have rated him five stars each answer, have no idea how it shows three stars for last question. Something to do with my last question not going thru?
