Yard hydrant, Pressure relief valve leaking continuously.

[Morgan Montague]

I had this PEX system installed in my yard about 11 years ago. I just turned on the outside water to it which was shut down for Winter back in November. It leaks continously when the hose hydrant handle is turned OFF. I suspect that this is a relief valve of some sort and that there should be something like a knurled knob where the water is squirting from? Am I correct in these assumptions? Also, who could I order a replacement from online? Thanks in advance good people

That's a frost free yard hydrant. When the handle is in the off position, that's the drain so that the water drains down and empties. It's not a pressure relief valve, it's a drain.
When the handle is opened up, it should seal. Are you sure it's not just draining down after being shut off? Or is that water under pressure?

If the plunger is bad those things just won't stop leaking. Probably going to need a new frost free hydrant, but they do make repair kits.

Those yard hydrants are designed for areas that freeze. The lower part is below ground, and the drain-back port discharges into some buried gravel.

You could just use a different hose bib with no drain-back, although that yard hydrant does give you a nice rugged mounting and can accept a padlock.

If you want to consider repair, look at the writing cast into the top.
