Frost Free Hydrant Leaking Underground. Eddipi (va) i just tried to use one of my yard hydrants for the first time since the winter. Place your ear on the top of the frost free hydrant, if you hear a hissing sound you will need to either adjust the plunger inside or possibly replace.
This unique design also allows water to leak from them without being seen. The shut off in the house is easy to get to and it's the only thing on the shut off. I'm very concerned that it may be leaking under ground somewhere.

I have several of the frost free hydrants scattered about the ranch. How much does it cost to install a frost free hydrant? In my experience these things leak for two major reasons. I have a yard hydrant freeze proof faucet that we use at the farm.
