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??

The green pipe is thin wall sewer pipe and is probably being used for the AC refrigerant and drain lines.

Manifolds are never to be buried beneath the slab. No joints under the slab except brazed…..

The pipe can’t run in the same ditch rubbing each other…..

That would fail inspection anywhere.

Mark,
Why are you roughing in jobs in Florida ?

Disclaimer: In no way shape or form do I think this is an appropriate install.

I am wondering, by the way those manifolds are all bunched together in one spot if they’re planning on boxing out the concrete to accommodate some kind of access to the connections.
Doesn’t look that organized

He said in his post that he was concerned about the splitting at where the expansion clamps started on the pipe
but it was too late to worry about this because they had already poured the concrete...
I assume its all been buried alive back in early spring 2022. o_O :eek: :eek:

Its not my problem

Pex A is grade A garbage. I'm a copper guy.

Not a big fan of the Buna-N orings in the propress fittings, I wish they were Viton as stock. I will use propress in exposed areas. 90% of what I put in is sweat copper. I do install some pex, but again, only in a few instances and we use Viega crimp pex(B) with machined bronze fittings.

When we run any potable or heat lines(other than radiant) under a slab we bury no joints and it's all sleeved with armaflex and even the insulation joints are taped. Mind you we have very few slab runs here as almost all houses have basements. We also don't usually install manifolds, we'll run a main and branch off, makes more sense for large houses with HW re-circ loop(s).

That's terrible plumbing. Future repair work for our kids.......

It makes me wonder how long those joints will last under concrete,,
someone will be in tears some day tearing up that floor and finding that mess
down in that hole

Looks like they'll get a rock or seven jamming into the pipe/fitting.

We don't do concrete with some rare exceptions so for us this wouldn't be any worse than working in any other trench where someone else digs it up.

Were roughing in a little slab tomorrow. We will be using pex, home runs to the 3 exterior spigots. everything else will be in the walls on the stack out. those pics though, that 30/34 with the 1/8 bend and riser is more than likely an ac chase line. Terry knows what hes seeing there. A lot of dryer vents in this area done the same way but with a 90 at the riser. we get a couple calls a year to come suck the water out of them. most of the stub out below grade, and turned up again. so theres no where for the moisture to go. but that water pipe is bullsh!t. what ever inspector let that fly needs his asss whooped.

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....
