SECTION 8 – Fire Protection Jones® Tell-Tale Break-off Check Valve The Tell-Tale Break-off Check Valve is a unique wet barrel hydrant innovation. When a wet barrel hydrant is hit and broken off, the Tell-Tale check valve shuts, preventing the loss of water and water pressure. In addition, it provides a visible “tell-tale” lowvolume stream of water to indicate that the hydrant has been damaged, yet does not present a serious loss of water or cause damage. Features of Jones Tell-Tale Break-Off Check Valve: • Minimizes water hammer. • Smooth flow characteristics minimize pressure loss. • Heavy bronze check valve construction. • Easy-to-reset design (no springs). • Easy to extend for grading adjustments. • Adapts to all current and past Jones hydrant designs • Iron, bronze and stainless steel construction. J-5000 How the Jones Tell-Tale Break-Off Check Valce Works: Diagram 1 When the hydrant is hit, the safety flange breaks, releasing hydrant from check valve. Diagram 2 Hydrant and adapter plate are released from lower barrel, and check valve begins to close. Diagram 3 Valve shuts and, working with water pressure, stays closed. “Through-hole” in operating rod minimizes water hammer while providing a visual notification of damage. Rev 10-18 5
