With pex do you cover the lines under the slab rough or just where they come
up through the concrete???? Most say you dont need it at all on pex but I wonder
if it is wise to do anyway?? Some day that chit is gonna leak but you might be dead
by then so who cares I guess.....

When I used to do 2 bathroom slab homes, , saving a few dollars was never on my mind .....
with type L soft copper I used to put aramaflex covering on both the hot and cold
lines completely under the slab......It probably cost me another 50 bucks at that time
but that was all the way back in 79 and we have never heard of anything going bad yet....
Just where it passes through the slab. No one would want to pay to have copper insualted in the slab. I’ve done that once on a million dollar home in 22yrs. Copper doesn’t do well in slabs down here. There are some soils that will eat it alive. I can’t remember the last time I used copper on a slab. It’s been 15yrs or more. But all commercial jobs even if it specs cpvc I use copper.

Well it might be more expensive to insulate copper lines in a slab but
I have never worried about the 50-100 bucks more that was gonna come out of
my pocket... I just did not want to hear any chit down the road from ground up
hot water lines in the slab...

If it were my own home I would 100% certainly insulate everything...

Insulation costs more than the pipe when you’re running pex buddy.

the material cost is one part, but the additional labor to install is another. 2 bath house with about 4 manifolds, and 5 home runs for spigots, ice maker ect, id charge at least another grand to do that.

Mark, I think you're MAD.

We always completely insulate lines under slab, pex or copper.

Why would you use pex instead of copper ?

I doubt you’d use pex, I could understand the idea behind insulating the copper but most people who use pex do so because of the price difference. Not always, but mostly. Some places the water and soil are not copper friendly. You can protect the copper but then it becomes even more expensive to install and/or possibly maintain with treatment and filtering.

I really dont care what they throw underground... pex or copper and ANYTHING is
better than throwing cpvc underground with glued joints too....

they throw the pex under slabs here and they feel it does not need any kind of covering
on both hot and cold lines....

I realize it will last out the warranty of one year but that is just not the level of quality
I would like to be stuck with if were my house..

I stumbled onto these pictures on another site talking about defects appearing in Wirsbo Aquapex....
This guy was not worried about all the joints he laid under this slab but more worried about will the
fittings spit and fail some day.....

When we did slab rough every joint was above the slab installed into a manifold
and only full runs were allowed under concrete with no joints...covered with aramaflex.

I dont even know what the green drain lines are all about or what kind of lame ass
pipe was being used here

How many people would be ok with whole manifolds under a slab rough??

I’ve got a buddy who owns a plumbing company in Ocala and sends me pics of other Jack legs doing this stuff all the time.
I’ve been doing plumbing 17 years in TN and I did for 1 year in Florida. Now we run Wirsbo pex in slabs but yes - no way are we putting joints/fittings in the slab.
Now I’m not justifying those pics or manifolds in a slab but I would trust pex and it’s fittings over Cpvc anyway if the week. I’ve ran Wirsbo for all my 17 years and the only split I’ve ever seen was on a 1/2” recirc return line.
That plumber probably left a roll of pex in the sink light for however long breaking it down.
It kills me that plumbers in FL still run that garbage to this day.
We can’t pull Cpvc out of the walls fast enough here.

I have used both pex and l copper and it appears I am more fond of the wirsbo pex over running the copper..

Yesterday I just cleaned out our back building where I had about 5 partial rolls of 3/4
type L and k copper just hanging on some hooks in the back room.... the stuff has
been sitting in the dark since about 1998 and I had no plans on ever using it..
The last slab I did with that copper was for some jack-leg that I had to about kill to get paid
so I swore off slab construction back in 1998

I did not want the stuff just laying around waiting for some crack head to break in
and steal some day so
I took it to the scrap yard and got about 500 bucks out of the clean copper and
another 150 out of some #2 copper....
