The Flomatic Model 8080SS is designed for installation on potable water lines where a cross-connection
could result in pollution of potable water. If a health hazard could result from a cross-connection, use a

recommends installing a Y-Strainer upstream of the valve to prevent fouling of the checks.

to valve.
