Has anyone used the Rehau pex? Trying to compare the Badger 5 wrap to the Rehau.
-
you can try many different products but will not find anything with the value that Logstor has in my opinion
-
Slim, I remembered Scott had said Logster was $14.75 afoot. I f I run Rehau or Badger through schedule 40 and keep it dry, wouldn't I be safe?
-
In your house its hard to beat Rehau, outside its hard to beat logstor.
-
Jwood is spot on!
-
Thanks Slim :thumbup:
-
Although I agree logstor is the best ditch ready pipe, it can be done better and even more efficient in my opinion. There is an article I need to find and post on here where a homeowner reduced his heat loss 75% by double tiling his thermopex vs burying it direct.
Im currently redoing my underground pex, tho I agree logstor is the best stand alone product, its not what I used
-
Just have a question, I just finished putting in my rehau pipe under ground and I have never delt with any thing so stiff and non plyable in all my life soooo if my rehau is polyurathane with the true inch pex in the middle how in gods name dose it leak? The outside rubber liner is super tough and when we spray poly on basement walls it never leaks please explain because l am a little slow thanks.
-
Who said it was going to leak?
-
Sorry I ment from ground water getting to the pex.
-
You shouldnt have any problems with that if you have the good insulated Rehau, I'm assuming you are talking about the stuff that resembles Logstor.
-
YES SIR.
-
Shouldnt have any problems then, Rehau is a quality product.
-
Ched, did you run the underground Rehau through schedule 40? Or is it tuff enough by it self? Would you guys run the Badger 5 wrap with the barrier or the Rehau?
-
He's talking about the encapsulated stuff -Rehau insulpex-
-
Jwood, have you used the Rehau? I'm trying to decide which product to buy and whether I need to run it through schedule 40.
-
No I have not most people on here use logstor due to the true 1" I.D. of the pipe, Rehau may have something similar to that size both are great choices I just believe logstor is a bit better. Others will chime in as well. Scott7m had mentioned something about a better method maybe he will voice it again!
-
Oh and the answer to your second question is no you won't need run either through schedule 40 pipe.
-
Jwood, I installed my OWB back in 08, towards the end of last summer after heavy rains I had water come into my basement from the corrugated pex. Man, I burned a lot of wood this winter. From what I have read it would be hard to make any bends through the schedule 40 with the Rehau. On e-bay 100 ft. of REhau is $4.49 a ft. the Badger 5wrap is around $ 6.00 a ft. I have an 80 ft. run and can't afford the Logstar. So am trying to decide which is better.
-
With that price I'm assuming that is not insulpex maybe its their foam wrapped stuff but if it was I'd buy it there is a post under portage and main from Sloppy Snood and in his post on his install he used a new seal, can't remember the name off hand.
-
Rock- after looking more into the stuff you are talking about I'm thinking this is what you are talking about and I would stay away from that.
-
This is the good stuff from Rehau and that seal is called link seal.
-
In regards to the insulated pipe im installing at home now I am using a 5 wrap product from z supply.
Why? Conduction of heat, creating barriers for heat to cross vs simply laying in contact with cold wet soil.
In one scenario a guy pulled thermopex through 6 in schedule 40 and saw a 75% reduction in heat loss vs burying it direct
He sealed both ends of the pvc and placed temp sensors inside to monitor it. With no hear flowing through, his temps ran 47-48, under full load at 180, the air in his "pvc plenum" stayed around 85, creating a barrier to the cold soil. He said it lost 75 percent less heat.
Why I went with z supply is its great about heat lost but I agree that logstor has tougher casing, so I pulled there 5 inch casing through 6 in pvc, the vapor barrier of z supply is another key factor, ur foam filled products dont have that I just took it a step farther to create another dead air space or pvc plenum for my pipe to run through
-
JWood the rehau you said was the good stuff is what I used, shewww that was stiff pipe!
-
I'm in the process of doing the same thing Scott7m is doing. Z supply looks like quality wrap and running it through the pvc
Would definitely create an air barrier plus keep it all very dry which is the most important thing.
-
Yes Ched bull that is stiff but it was good quality wasn't it? And that first pictured stuff I wouldnt waste my time with it just looks like a cheap alternative. The way Scott and Elvis are doing it sounds like good way as well if using a 5 wrap I wouldnt bury that alone, I'd do what Scott is doing.
-
The nearest Z dealer is over 100 miles away from me. Still looking at the 5 wrap Badger. How much a ft is the Z plus I would have to pay shipping.

we ship it all over the country.... the insulation is thicker and a higher quality buy your gonna end up maybe 8 per ft with shipping
-
Scott, thank you for the response and I will keep thinking and planning this job. Only going to do this one more time. The Logster and Thermoplex are just to expensive for me at this time.
-
Yes JWood you are 100% right and by george I believe Scott is on to something, this that Scott is going to do may even be better plus cheaper.
-
I bet he will let us all know how well it works!
-
Yes I will let you all know how it works out
I dont expect any mysteries or surprises really as I know others who have done this
-
Thanks Scott :thumbup:
-
Scott7m have you put any thought into putting a radiant barrier around the Z supply pipe before you shove it through the pvc pipe. I have been pondering that my self not sure if it would help much.

This is what I planned to do when I replace my lines this summer. From the house to the boiler already has a buried 6" PVC pipe. Correct me if I'm wrong Scott, but I'm betting you slid each ten foot section over the 5" instead of trying to slide the entire length of five inch thru a already assembled six inch pipe?
I took a piece of five inch drain tile and its a snug fit inside of a 6" PVC. I just can't see being able to pull it thru 80' of already buried pipe. I was thinking of using three wrap to replace what I already had, it should be much easier to coach thru the 6". If I think I have room I was also thinking about pulling a 3/4 or 1" water line along with it so I can have a hydrant at the boiler. The new line I'm burying to the shop will have five wrap. It's not feasible to dig the old one up with the landscaping, well head, etc that wasn't there when I buried the original.
