This 4' diameter piece of pipe is sunk in the ground and sits about 3' below
ground with another 2' above ground and houses the pressure tank for our
well. It is only covered by a piece of plywood and a tarp. Inside, the
previous owner had a bunch of glass batts wrapped around the tank and tied
with string. He says that he hasn't had a problem in the 5 years that it
has been there but the winters haven't been that bad of late. I'd like to
do a better job of this. I thought that I'd cut a 4" thick by 4' wide
circle of foamboard and lay it on supports just above the tank to avert some
of the cold from above but I thought that I'd like to insulate the sides of
the pipe but with what and then I may have an issue getting the circle out
if I need to service the tank, depending on what is done with the walls.
I'd like to hear some suggestions for capping the top too, with relatively
easy access in mind.
TIA,
