Yard hydrands, like fire department hydrants. Very often,
there is a controlling rod, the actual valve is below the
frost line. There shoul d be a drain on the bottom. When the

into the ground.

Of course when the valve is closed the water should drain out of the
weep hole but my hydrant is NEVER closed thus there is always water in
the standpipe from approx. 4' underground up to the top of the hydrant.

Well CLOSE it after you use it or someday it will freeze. If we leave
it open up here in the frozen north it will freeze. They are designed
to drain once you close them off.

Stormin' Norman has it right...read his posting and learn.

You must be further north than I am because it has been open for 6 years
and has not froze yet (knock on wood). It is not like it is sitting out
in the open, it comes up through the concrete slab floor in a building
that is always heated to 45 degrees F and sometimes up to 68. The only
place that it might freeze would be between the floor and the frost line
which could get as deep as 30".

where are you? We have a lot of lines around here (KC area) that are at
24". They don't freeze at that level. It takes a loooooooonnnnnnngggg
hard freeze to get that deep.


Extreme SE Iowa. If you would go straight up #35 and then turn east on
#2 in IA and continue east until you are about 20 miles from IL you
would find me. Obviously, north of you. And yes, I have seen water lines
freeze that are 30" deep up this way.
