Comments: I let this sit a few months before installing. It was in the package and not opened until install. It leaked as soon as I turned everything on the reactor back on.

Comments: I purchased these check valves to replace the faulty brass check valve which came with a Korallin Calcium Reactor. The first valve leaked immediately and allowed water to backflow into the needle valve. So...I installed another new one thinking the first one was faulty...same scenario, it leaked. Note that in addition to allowing water to flow back into the needle valve, water also leaked out of the plastic housing. I'm sending these back and going with a different option.
