OT: Yard hydrant

Be aware that a hydrant (yard or fire) should only be all the way open or all the way closed or it may/will undermine it self.

I had one that was being held open by a small rock, we could not figure why one of the lawn sprinklers was plugged with sand? The flow of water past the partly open drain caused suction and drew the sand in. All is well now.

But just to clarify; the yard hydrants may dribble a little water for a few seconds as they are first turned on, especially if the handle is moved slowly.

They should not "pee" water continuously out the drain hole once the handle is fully on. This would be just asking for trouble.

In this era of backflow preventers and rampant regulatory fear over cross contamination, I suspect that the yard hydrants may no longer meet plumbing codes....

"Rampant regulatory fear" is a great phrase. It's too bad that it can't be used as a petroleum substitute; I see no shortage in the foreseeable future.

All the best, Stan

Yep, that be normal.

When you shut off the hydrant the drain allows any water in the standpipe to drain back down and protect it from freezing.

So, if you have the hydrant "on", she's dribblin' underground also.

It should not dribble water while flow is going through it. other than a possible tiny bit for a second as things pivot.
