Actually I have... on a 1,000 ft run using a remote hunter 4 valve controllers . The guy that low balled my maintenance contract didn't have a clue how to program them or even change the batteries.
Long story short; he disabled the zone, the ground turned into a fine silt like sand and everytime the LCO ran his tractor over the pipe, it forced silt down and the pipe came up.
When I did the installation, all the pipe (excepting the swing pipe to the rotors) was down 30" Now it's just below the surface in places.
Not this guys problem though. I'll bet he had ground water freeze and force the pipe up
