Yard hydrant runs when handle is shut off AND water flows up from the ground around the pipe.
Worked just fine when we opened it last week, wife went to water plants today and told me it wouldn’t shut off even with the handle completely closed. Went to inspect and noted a few things: water did indeed flow even though the handle was off; water was coming up out of the ground around the standpipe; pushing faucet head straight down into the ground gave noticeable slowing of water flow from spout and ground, the fixture maybe moved an inch or two vertically. Only way to stop the water flowing for good was to shut the well pump off. Am I most likely looking at having to dig up the standpipe and replace the entire unit?
