If you have a daily need it may be worth your while to have a frost-proof
anti-siphon hydrant valve installed. Try googloing "frostproof hydrant"
for some examples. These valves have a rod or linkage above ground,
and the actual valve is below the frost line. The linkage operates the
valve and water comes out through the above ground standpipe portion.
When the valve is closed, the water in the upper part of the piping
automtically drains, so no ice can form.
