Proper Care of Post Indicating Valves
A local home improvement store recently called Cherokee Fire because someone had ran over their outside Post Indicating Valve (PIV) with a vehicle.
Our Service Technicians quickly replaced the damged Post Indicator and the store was back to business.
What is a PIV? Well, it's a valve which indicates if its Open or Shut. These valves usually control water to fire sprinkler systems and its important to visually verify, on a weekly basis, that the valve is Open.
The valve should be equipped with a special wrench to operate the valve and it should be exercised (fully Shut then Opened) every 3 months. Proper exercise of the valve will help ensure a trouble free operation and reduce expensive service calls to rebuild valves frozen in the Open position, or difficult to operate during annual sprinkler inspections.
