Some of the frostproof ones have a backflow preventer check valve at the interior end of the valve. Maybe that's wadded up.

Thanks! This has the built in atmospheric vacuum breaker on top. I unscrewed the top and repacked the guts, but the water wasn't making it to the breaker.

Post the manufacturer and model number. The frostproof ones can generally be rebuilt from the outside, but they can be a little complex.

It's a Merril 1019A, it is NSSF ASSE stamped.
It's in good condition. Is it possible to have a temporary lock come and go and be in the copper service line? No other weird water issues in the house. {well, jet pump, 35-50 pressure cycle). |

I would pull the shaft behind the handle to take a look at the guts. See if the screw has backed off too. Have some plumbing grease on hand to put on the end of the shaft and washer.
Hopefully you have a shut off valve behind the hydrant. |

Hopefully you have a shut off valve behind the hydrant. Unfortunately no shut off, but killing the pump isn't a problem. I think you are right, I didn't realize there was an internal check valve in the valve stem. The interrupted service acts like a check valve that is prone to hanging up. Will investigate.....thanks! |

Got it! Thanks everyone!
It was a hung check valve in the valve stem. When I would pull the guts the check valve was not coming out (both when pressurized or not) I could barely see down the valve stem, but decided to jingle a long screw driver and eventually the the check valve popped out. I repacked and A OK for now. |
