When we bought the place we live in 2012, we had a yard hydrant that was seized and couldn’t be turned on. With a new garden plot on that side, near the barn. That would have proven to be inconvenient, had we not had more than our share of rain this summer.
I have been working lately to dig up the offending hydrant to replace it with a new one. Here in Iowa, the “extreme” freeze line requires the water lines to be five feet deep to avoid having your water freeze up on the coldest winters.

The rusted, formerly galvanized pipe, leads me to believe this hydrant has been in the ground a long time!
I can tell you tonight I am feeling every shovelful of dirt I have thrown out of the hole. We bottom two feet was definitely still plenty wet (and heavy and gummy) from the earlier rains.
The block structure is a previously used well pit. The blocks are merely stacked and not mortared. When the water was converted to supply by the local rural water supply, the metered water was connected in the existing pit and the well was retired (I was told the well was sulfurous, which might explain the bad drain and waste yard hydrant). There are cut-offs in the pit, which I will need to access when the new hydrant is installed.
Right now I am looking for a source for a stainless tee than can insert into the poly pipe and provide a 3/4″ NPT (normal pipe thread) to attach the new hydrant.
These hydrants have a drain hole near the bottom that allow them to empty when shut off so they don’t freeze in winter. It seems to me the four-inch drain tile and handful of rocks (still on the ledge next to the block wall) was a pretty poor installation, given that the level of the drain hole is in a pure clay strata.
