The PrimoChill Pressure Check Valve is a stop fitting that allows air to escape once pressure has built up in your system. By installing this on the top of your reservoir or another high point in your system, the pressure check valve will exhaust air to alleviate any pressure build up. Installing this pressure check valve will help eliminate air locks in your loop and make the priming (filling) process of your system much easier.
