Underground Pex choice

[MrEd]

Found this on ebay:

http://cgi.ebay.com/1-1-4-Insulated...20598QQcmdZViewItemQQ_trksidZp1742.m153.l1262

100' of 1 1/4 pex, insulated, comes in at under $5/foot plus seller will sell customer lengths.

But also, found this stuff:

Which to my untrained eye, looks better BUT at $28+ a foot (over 500% more than the stuff above).

Question is, will both of these work OK? At 5X the cost you start to wonder how much better it could possibly be? Especially if I went down 4-5 feet in the trench...

Opinions?

this is the pipe i used. i havent run through the winter yet to see if melts snow but i did have alot of water in the ditch before i finished burying it in a rain storm. i dont loose any temp in a 250 foot run. im not trying to sell this product its just what i used. im happy so far but ill know more after ive been through a winter.

Just be sure whatever pex you use has an oxygen difusion barrier beacuse if you're running a closed looped system your boiler & any metal parts in your heating system will be a bucket of rusted out bolts in as little as 5 years.

good point, the pipe i purchased was oxygen barrier pex

I have been very happy with Thermopex that I got through a Central Boiler dealer. No noticeable loss over a hundred feet of travel at 18" burial depth.

When I ordered alumapex pipe I ordered 1 1/4 and found upon its arrival the dimensions are external diameter ASK QUESTIONS so you know what you are getting as opposed to what you expect to see!!

You get what you pay for. The first site is kinda like I have but I put mine in 4 inch drain pipe and won't do that again.

Just save your money and do what I did.......

Regular old oxygen barrier pex, buried in trench and sprayed with Corbond... I had 250' of trench and insulated a ton of lines (two to one location, 4 to another, and 6 to the last location) with insulation barrier between all hot and cold lines and 4 inches minimum between any line and the surrounding dirt...... $1600 for the corbond, installed...... (R6.6 to the inch)

So.. that figures out to be $6.40/foot.... So, unless that rhinopex stuff has pex lines made out of gold, it's a rip-off......
