About this detail

An automatic controller connects via a Paige electrical P7200-D cable and two number fourteen wires housed in one-inch polyvinyl chloride conduit to a master valve relay and flow sensor box. The pressure supply line features a flow sensor sized per plan and a master control valve normally set in the open position, both housed within twelve by eighteen-inch plastic boxes and covers with locks marked F.S. and M.C.V. respectively. Threaded fittings use thread sealant number 8200, and all wire connections are waterproofed. The valve boxes sit flush with finish grade in turf areas or two inches above finish grade in groundcover areas, placed atop a minimum six-inch depth of three-quarter-inch pea gravel.
