Sealing SonoTube for use as an access port
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?
