The black plastic becomes brittle in the cold, so don't run over it with trucks or snow machines. It needs to be drained, we blow air through ours to make sure. We cap off the ends with screening so critters don't look for a home but it still drains of condensation. Otherwise in the spring and the start of the season we find air leaks at the fittings and over the years pin holes develop in areas; these cause the prime to be lost if you can even get it. Otherwise leave it out.
