We recommend a valve box along with a full port brass ball valve and aluminum cam and groove coupling for underground water supply connections. The full port opening diameter across the valve and the cam and groove coupler does not compromise the connection diameter. A high degree of hydraulic efficiency is maintained across the connection, while still maintaining an easy convenient connect and disconnect. When not in use and the valve box closed, the valve is protected from traffic and retains an attractive grounds profile. Call us about the bill of materials for this installation. It is important to use a metal ball valve with a metal ball and synthetic seat to avoid the problems associated with plastic ball valves and grit.
