FROST-PROOF YARD HYDRANT

HOW A FROST-PROOF HYDRANT WORKS

CLOSED

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.  

CLOSED - DRAINING

Closing the handle pushes the plunger
down to seal off the water and uncover
the drain hole.  This allows the water in
the head and riser pipe to drain back
down into the gravel drain bed.  The
hydrant is now empty and cannot freeze. 

OPEN - WATER FLOWING

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.

®

LEAVE THIS SHEET WITH END USER. 

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.
