The American Water Works Association (AWWA) recommends that all water utilities departments initiate and maintain a comprehensive valve-exercising program. This program should include inspecting and operating valves (including distribution and transmission valves, air valves and blow-offs) on a regular basis.
A properly implemented valve-exercising program ensures proper location, operation, and condition of valves. The physical operation and documentation of such operation are important and necessary for asset management systems and capital improvement budgetary planning. Ensuring valves work properly can also improve customer relations by allowing for system isolation capabilities in the event a repair is needed.
VALVE EXERCISING PROGRAMS
A comprehensive valve-exercising program should have four main components.
1. Location of all valves located in the water system
2. Exercising each valve
3. Maintaining records
4. Scheduling and performing necessary repairs
Valve exercising should be performed at an interval that will prevent tuberculation from building up in the pipes. Tuberculation could render your valves completely inoperable or even cause incomplete shut down of a pipe.
EMERGENCY VALVE OPERATING
If you have seized or broken valves, call us to evaluate your large diameter valves to see if repair without excavation is possible, saving you time and money.
WE CAN EVEN REPLACE BROKEN/ROUNDED/MISSING GATE VALVE NUTS WITHOUT EXCAVATION!
