I want to use a SonoTube as an access port for an underground valve. The
valve will be about 4' under ground. I thought if I painted the ST and
wrapped it in plastic it would hold up much better. It won't last a
thousand years, but it should meet my needs. I'll insulate the Tube to
prevent freezing.

Any ideas on the best way to mummify my Tube?

A piece of large ABS seems appealing, but I thought it would be
expensive. I
was thinking of Fibreglassing my SonoTube, but I've got enough **** to do
without creating work.

Access is for a Pond shutoff for those that asked. It needs to go around
a
large knive valve, so it's likely 6" minimum.

If you use a Sonotube, remember to waterproof it both inside and
outside, as water will likely leak into the well at some point (maybe
a lot of points). More reason to use something made of plastic
instead.


Thanks,

I ended up buying one of those round sprinkler boxes, a closet flange and a
piece of 4" pipe. The sprinkler box isn't intended for underground, but I
think it will be OK.
