Do the pipes buried in the ground need to be emptied for the winter to
prevent bursting? I am contemplating a series of valves in my design that
will allow me to close the pond off, and use the pump to suck the water out
of the pipes. I figured this would be good for cleaning and for winterizing.

Do you think it is an unnecessary expense?

my current setup has the pipes running just under or at the surface of
the water with no way to drain em
when the pond ices over the pipes are encased in the ice so far no
breakage in the pipes in the yard some of the garden piping is at or
just above ground level with most anywhere from 1- 12 in down when it
gets below 10 degrees I have had the above ground pipes crack but so far
none of the underground pipe has cracked.

hope theis helps
