I reinsulated my underground pipes after 30 years in the ground. I made a video of what we did.

Redoing the underground pipes on my wood boiler

I'm getting less than a degree drop over the span and so far it's working just fine.

good video MrDan.  You definitely have enough insulation on there.  I would be worried about that pipe being split all the way down though.  Even though it is on the bottom I would think that water would still find its way in there.  But hey, if it works then it's all good!

I was worried about that too. In fact I still am. I can always pull it up and redo it with commercial PEX later if need be. At the time this was the best option I had, especially since I didn't want to cut and replace the pipes. Splitting the corrugated was the only way. 

This weekend I spent half the weekend getting inside my in-house 500 gallon water tank/heat exchanger setup. After 30 years it had started leaking. 5 hours of grinding/cutting, and 2 hours of welding and it looks like it's holding water. A 14" crack had developed in the bottom right on the seam of the tank. Kinda hard to call it a manufacturing defect after 30 years but it sure looked like the weld wasn't done very well. Anyway, I'm not scared of some weekend work so if I ever have to replace it, no big deal, I figure I can get 5 years out of it easy even if it doesn't do exactly what I want. I'll hopefully have time to order the PEX in and have it ready to go should that day come.
