So since I'm in a question-asking mood (and thanks very much to everyone for the great suggestions on the sonotube-and-high-water-table thread): What do y'all know about repairing frostfree hydrants, the kind that go 4' down into the ground with the drainout valve at the bottom so that no water remains in the standpipe when the water's shut off (unless you forgot to detach the hose )? My situation is this: The chickens' building has a slab floor and the hydrant stem goes down into a little hole thru the concrete, barely wider than the pipe. I assume the bottom of the hydrant pipe where it attaches to the water line from the house is roughly 4' down, as that's code (and common sense) in this area and this particular building is built very well and properly (not by me). Problem is, through overuse of disinfectants when it was a kennel and/or the ensuing years of disuse, the top part of the assembly -- the red-painted head and handle -- are totally eaten up with corrosion to the point of nearly falling apart. (the galvanized standpipe is fine). Also the handle sticks very, very badly -- dunno whether it's in the upper part or down at the bottom end of the rod, underground -- and when it can be induced to emit anything, you get a poor flow of very rusty water. So if I were ever to try to do something about this -- tho it ain't gonna be this winter -- do I have to break the concrete up around the pipe so I can dig a reasonable hole down there and excavate the whole thing up? Or is there (please, please tell me there is!) some way of removing the top of the hydrant, taking off the handle and spout and the long rod thingie that goes down to the bottom, and replacing just that stuff without any actual excavating? Pat, with only primitive plumbing skills and never having seen the innards of one of these things.
