PEX Install Questions
« on: September 15, 2013, 08:00:40 PM »

I've got my Underground mostly installed but have a situation.
My house is on a crawl space and the utilities underground interfered with my pex underground. So I'm going to have to come above ground level for the last 6ft. I will build a patio over the pex so there won't be any trouble there but,,,,
Do I insulate the insulated pex?  Should I use foil board and box it? Foil board and wood inclosure?

I really could use some advice.

I think most important is, will it stay dry? the more insulation the better. I would cover to protect from critters.

So your wondering if you should insulate your already insulated line because its going to be on top of the ground...   

It could be a good idea I'm case of a big power failure lasting a couple days, as far as how to do it depends on where you live and how cold it gets.  We've had to do that and we'd cover it with dirt instead of digging down

I'm in Arkansas so not artic temps. I do want to protect the pipes and add a little insulation. I will have this OWB wired to my generator so I can have heat in a power outage.

The patio that I'm going to build will protect them well but I want the best setup I can have.

Here is what I did.  I took a 4" roof flange and cut out a 6" hole, because I'm running 6" pvc.  4" may work perfectly for you.  I put frost king cellular insulation around my pex and fed it through the pvc.  Run the PVC through the flange and presto!  A little foam and silicone and it's pretty weather tight!

That looks really nice and seems cost effective. I'm going to see if that will work for my application.  Thanks for posting!
