Today I saw the town maintenance man repair the elbow in a 2" plastic
water pipe, two feet deep in sandy soil.

He said water pressure had separated the joint. His solution was a
steel stake on either side of the joint. That's what he had before, and
it failed.

It seems to me that enough pressure to separate a joint could also, in
time, move a stake in wet, sandy soil. Is that the best way to brace an
elbow undeground?

I'm curious what kind of plastic pipe it is and is it glued, clamped, or
crimped to the elbow?
