HOW A FROST-PROOF HYDRANT WORKS | ||
CLOSED | OPEN - WATER FLOWING | CLOSED - DRAINING |
The hydrant is closed and no water is in the riser pipe or head. Water is stopped by the plunger (valve) below the frost line. Protected like this, no freezing can occur. | Water is made available by raising the handle. This will lift the plunger allowing water to flow and the plunger to seal off the drain hole. NOTE: WATER FLOW CANNOT BE THROTTLED. Hydrant handle must be positioned in the FULL open position for proper water flow and drainback seal. This hydrant will not operate properly in a PARTIALLY open position. | Closingthe handle pushes the plunger down to seal off the water and uncover the drain hole. This allowsthe water in the head and riser pipe to drain back down into the gravel drain bed. The hydrant is now empty and cannot freeze. |
