Tank has been being water testing for the past two weeks. Tonight I moved the tank into the house from the garage and now the overflow bulkhead is leaking. Who sales 1 in bulkheads? Anyone know what is the stock kind of bulkhead with oceanic tanks? I can't tell if it's slip/slip or what. Can I just change out the gasket and keep the bulkhead so I don't have to redo some of the plumbing?
