Type of in floor

[Jim Robinson]

Any idea what brand this in floor tubing is? It was installed around 89 or 90.

[H.G. Watson, Sr.]

Horrible picture quality, can't even be sure its black?

Sure is enough of it you should be able to see a marking or tell us something about it.

Suppose it could be Onix, but that's a WAG can't see anything distiguishing in your pic, and gleen little to nothing from your description other than apparently is hydronic radiant tubing.

In-floor doesn't necessarily mean in-slab, no details, bad pic, can only WAG.

[John Arnold]

Jim - It appears you've just ruined H.G.'s day. He's very upset due to your forcing him to WAG.
I think you owe him an apology.

[Jim Robinson]

Yeah, thanks for the help HG. Yes, it's black, and it's in the slab. No there was no writing on it, or I would have mentioned what the writing was, and/or looked it up myself. Maybe your monitor is out of focus.
