Materials

About this detail

A brass stop and waste valve is installed underground within a filter fabric lined, 12 inches wide by 12 inches wide by 24 inches deep washed gravel sump, plumbed to a depth of 40 inches or matched to the water supply line depth. The valve connects via a minimum 8 inch length brass nipple and brass elbow to the water supply line, and extends upward through a notched 2 inch Schedule 40 PVC pipe. A 10 inch round valve box with precast concrete pavers and washed gravel surrounds the extension, finished flush with grade. Green colored valve boxes and lids are installed in lawn areas, while tan colored boxes and lids are used in planting beds.
