I've been pumping in an STJ for the first time and love it!

However, the pressure is constantly dropping. It's not around my body, or at the glass, but rather I think it's leaking at the valve where the hose clips in.

Does anyone have any suggestions or pro tips on getting that to stop leaking?

There should be little "O" rings on the inside and outside of the hole in the jar for the fitting and its nut. Perhaps one of them is partially in the hole or maybe the nut just isn't tight enough. As a test, try putting a drop of dish detergent on the outside where fitting meets jar and see where the bubble appears on the inside. I suppose that the fitting itself could have a crack - most are made of molded nylon.

Thanks! I don't think it's th o rings but rather the connection between the hose and the quick snap port.

Would somegow taping that connection when in use help?
