For what reason would you want to? I would not do it unless there was no other way.

Real pipe ? Then yes, have done logstor several times, just use their splice kits. Special order

Id be weary of having a splice with the underground piping.. I wouldn't do it..If the splice was in your basement or something..sure why not.

Yes he has logstor or "reap pipe" as you call it.  It was my logstor distributor that said he don't recommend splicing it

 I would     just leave it uncoverd for a few days to make sure its not leaking and back fill with sand !

If it has to be done, I would use Rehau Everloc fittings

Just put the connection in a drywell or a underground vault so you can check it. If and when I move my OWB I will be using a concrete vault to connect the existing lines together, the new line will be at other end of the shop.

Sprinter, I'm about 15 foot short from where I would like to install the unit. I was told by the dealer that I got the pipe from you could use a splicer kit from Logstor, I just wanted to hear from someone who had used the kit. I'm sure it's not the preferred way to install Logstor but guess ill have to make the best of the situation. Is the kit a water tight box, or can you dig it up to check for leaks, thanks for the info.

Not sure if they changed it but no it was a set of couplings and a sleeve, I like the junction box theory much better as you can have access all winter in case of a problem, Have you ever tried digging frozen dirt with a shovel?

I think the only way I would want to do that is through a box like cantoo suggested.

 We use these underground jboxes at work: http://www.hubbellpowersystems.com/literature/enclosures/QZ-2.pdf (http://www.hubbellpowersystems.com/literature/enclosures/QZ-2.pdf)
 They are durable, of course there are other brands, some are completely plastic, rate them for what load will be driving over it. They are not always that easy to get into during winter or wet weather, they tend to fill with water and freeze which breaks them apart eventually. I would choose a bottomless box and line bottom with crushed rock so it can drain but some soils won't drain well anyway. I would try to splice it horizontally with the kit then slip the box over it with slots cut in the sides.

I think the most important thing to do is make sure that the out jacket/sleeving is sealed; water infiltration KILLS insulation.

If you use manufacture properly splice kits, there won't be any issues. Access is a good idea, as long as you can keep water out. Near impossible in some soil, and if the ground freezes, the box just became a mini pool.

Just for kicks, some should submerge some spray foam and see what it does.

Well PTL my wife is so gracious. I can put the

 unit where I originally planed and will have 10 extra foot of Logstor. No splicing needed. Don't you just love them.
Lot of good feed back on this subject, thanks to you all.

If your wife is anything like mine, you don't get nothing for nothing, Hold on, retribution is coming, might be hard to sleep at night for a while. Glad it worked out for you.

Short of dragging the mini X there, I will be glad to check out Marty's line set. Just keep me updated when the dig will begin.

I am more than certain he will let you know,  there is already plenty of pictures on here of his lines

are there pics of the actual pipe and connections? I might have missed it but all I did come across was some snow melting on the ground.

There was but not sure if there still here as the admin deletes direct pics often

I talked to him last night and I can assure you hell be making a public invite to you to come up.  Hes also going to make a video of it, showing the places where his casing split.  he is also going to put a piece of it in his vice for folks to see water come out of it.  He has been putting thermometers in the soil above his deep buried thermopex and the ground temps above the line set are often over 10 degrees warmer

Hopefully it will be a good learning tool for all

I like that idea cantoo!

Thanks, any idea when, and what county?  When you say deep, I thought his post said 18", either way it sucks. And if it hasn't been dug up yet all diagnosis are speculative guessing so far. If it does turn out to be a manufacturer defect in anyway, I'd be willing to bet the manufacturer will cover it, and keep the story quiet. Just from other pipe manufacturers responses to failures and what they did to remedy the issue. Its a sales and reputation killer for sure. So documentation is critical. I don't have any problem helping someone out that gets boned by the big guy. As I'm sure many others will to.

You'll have to ask Marty the full details,  but I think I remember him uncovering some of it to find splits and I think they sent him some mind of tape to put over it, but don't hold me to that as I hear so many stories it's hard to keep them straight

But he will contact you I'm sure

I'd bet money on it, any takers, even money.
