If you go that route, run a "Sleeve" underground with a straight run
of 1" PVC Pipe, and heat bend the pipe to make radius sweeps like
conduit. Or get the black polybutylene tubing used for sprinkler
water lines, it's flexible enough to bend. Put any thermal insulation
on the outside of the sleeve pipe.

Rig up drain fittings at the low spots so it drains into a gravel
bed, or out on the lawn, or into the basement drain system at the
house. Then pull your 1/2" PEX water pipe through in one piece.

And WHEN it freezes and bursts the PEX pipe, and you see a river
coming out the drain, you just re-pull the PEX through the existing
underground sleeve and you are all done. No digging, no concrete
cutting.

Think ahead, determine failure modes, and guard against as many as
you can.


Why not just bury it deep enough it never freezes?
