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.
We were looking for a cleaning product in and around our daycare, kennel and training facility that was safe for the dogs. AgriSyn is not only completely safe, but has a very clean and fresh smell
