5 wrap survival is all how you backfill if you do it with rocks and gravel we all know what will happen if you prep and backfill correctly then you should be ok.

In this case it must have got a hole in shipping.  We live in Iowa and his yard was just nice black dirt.  Regardless, wouldn't have been an issue with foam filled.

Yep.  Even with the foam filled you should use fine sand around the pipe.

I put my logstor inside a 6 inch pipe just to make sure and then a 8 inch culvert where I drive over it. Then back filled around it with screened 3/8in gravel.

A friend of mine bought 5 wrap from the dealer he bought his stove from.  After it was all installed, it filled with ground water up to the top of ground level.  So, from his boiler to where it comes up through basement floor, is about 150 feet of underground line all full of water.

Apparently, there was a hole somewhere in the outer jacket and after some hard rain it completely filled up the tile around the pex and 5 wrap.  Now what?  Well we came up with a solution but what a PITA.

Therefore, the next time I buy pipe it will be closed cell foam filled.

For this project a trencher won't work so i will need a backhoe to come in to help.  The guy who's doing the job has a wood boiler as well.  He turned me on to a product called Insul-seal.  It's basically PVC pipe with closed cell foam on the outside and then a thick plastic covering, then you pull whatever pex tubing through the conduit.  It's made in a town just 30 minutes from my place, in SE Minnesota, and I'd love to give local business my money if their product can compete with other reputable buisnesses.  However I've tried calling the company three times now, filled out their contact info on the website with my email and still haven't heard back...  I'm very quickly loosing interest in their product.
