Many municipal and private water systems use 3/4 through 2‐in. (19mm through 50‐mm) handwheel gate valves to isolate sections of their water service systems. The most common problem encountered with such valves is leakage past the valve stem packing. Because of the high cost associated with the excavation of paved streets, it is not uncommon for water departments to permit such leakage to continue until it becomes severe. The handwheel gate valve repair tool allows the waterworks operator to replace broken handwheels and tighten leaking valve stem packing nuts without having to dig up the valve box. This article gives information on constructing such a tool for an approximate cost of $5070.
