Valve Boxes & Lids
CP Test Services – VALVCO valve box risers are slip type adjustable from 2 ½” to 8” elevation height. Our valve box risers adapt valve boxes situated too low or high. If too low, you’ll position valve box adapter in the existing valve box, pour cement around and press down until riser rim is flush with the new surface level. When the valve box is too high, break off the top of the valve box, slot in adapter, pour cement and push down until riser rim is even. Designed to minimize unnecessary steps, when finished, you just replace with the existing valve box lid and move on.
