Return Valve is built out of brass with a viton seal and a 1/4" compression fitting. This check valve is designed to keep a positive pressure on the system for immediate starts and quick shut offs. This is factory pre-set and needs no adjustment.
The Shoo-Fly system has a tremendous ease-of-use. It is easy to clean and service. If we ever have a problem all we do is contact them and they provide an immediate solution.
