So, I have a titan tank I was playing with, and as the epoxy I had was kinda messed up, its been sitting for a week drying. While I was randomly pumping it up and discharging it, the tubing to the pump blew off at the tank. I had time to kinda stare incredulously at the two parts, and then checked the tank, to find to my surprise, the tank was still pressurized. So, I went looking to see if there was a check valve in the tank, and can not find anything about the actual internals of the tank. Could not find any so was wondering if anyone had ever opened up a titan tank and if there was a check valve in the tank itself?
