Frost Free hydrants are the way to go if you have to carry water very far. Any hose has to be removed every time, drained, and stored someplace above freezing in the winter.
A few more tips, mostly learned the hard way -
-Dig your trench deep enough to get below the frost point. Remember this is much deeper in areas where you shovel or plow in the winter. The hydrants come in different lengths depending on how deep you need to bury them - 6' up here. Put sand at the bottom of the trench, and around the supply pipe, and foam board insulation on top of the sand before backfilling.
-In poorly draining soils, dig a deeper hole where the hydrant will stand, and fill with pea stone. This allows the water in the standing pipe, which drains out a release valve at the bottom when the handle is closed, to drain away from around the standing pipe.
- If properly adjusted, any water drawn back into the pipe when the hydrant is turned off will drain out below the hydrant and not back into the water line, but still better to pull the hose end out of water before turning the water off, to prevent contamination of your water line.
-Backfill with sand and/or pea stone, as you will inevitably eventually have to dig that sucker up.
-Always unhook the hose when turning the pump off (not necessary for a short bucket fill hose). Turn the handle on and off after removing the hose in the winter. If the hose is still attached, it might not be able to draw air down into the standing pipe, which leaves it full of water and at risk of freezing. Ours was maladjusted one year and we had to heat tape and run a stream of water all winter to keep the pipe from freezing, very inconvenient and a frozen icy mess.
