A.Y. McDonald’s new slimmer inline dual check valve is designed to protect the public water supply by preventing the reverse flow of water from the building back into the water main. The valve is capable of holding 1 psi in the direction of the flow, but also can endure a temperature rating of 34° F to 180°.
