If you drill hole in floor that would not be fitting problem, and would require you to dig up damage tubing to make repair with coupling ans short piece of tubing
Do you know what brand PEX tubing is in floor ?
With date of manufacturing?
Thanks for the reply. Perhaps my question was a little vague. I'm not actually concerned about the puncture I made in the floor. It was in my researching on how to repair it is when I became concerned. I've come to find my entire radiant heating system is done with KITEC tubing, which I know now is faulty. KITEC was successfully sued in a class action lawsuit.
From what I've been reading, most of the issues with kitec is with the brass/copper fittings corroding with the aluminum core of the kitec tubbing. I'm taking that as a positive since I have to assume there are no fittings anywhere within the concrete floors for the radiant system. There are, however, brass/copper fittings at the manifolds. And I understand that crimp connections are better than compression connections. So
So my question essentially is: are the legitimate concerns about kitec as relevant to in-floor radiant heating systems? Do I need to have my entire radiant heating system replaced?
Ok. So to be clear, the problem with kitec is fitting related and not tubing related, correct? Either way, the tubing does have fittings - at the point where it starts/terminates into each pump for each zone of the in-floor radiant heating system. Please see attached picture. It looks as though said fittings are compression type. And there may indeed be fittings somewhere in the radiant system as well, as I cannot be 100% certain that each zone is one continuos kitec tube. So I can I assume I still face a potential issue with the kitec? How do I determine if there's a potential problem lurking? Right now, each fitting seems fine - no visible signs of a problem
Thank you. One more thing if you do not mind... Perhaps I could glean something from those articles, but do you happen to know what I should be looking for at those fittings in the picture I attached earlier? Are there visible warning signs? And I believe my fittings are compression style, correct? Is it 'easy', relatively speaking, to change from compression to crimp fittings? Thanks again for your time.
Thanks again. As you suggest, I'll continue to do research. So last but not least... As you say, the underfloor tubing should be fine for a long while. And it is this underfloor where I have the kitec, the rest of the house (ie domestic water use) is not on kitec. So in summary, it sounds like my most likely point of failure will be at the fittings into the manifolds/pumps. Are you aware of a product that I can replace said fittings that will not corrode with the kitec? I'll await your answer the close off this discussion. Your time has been greatly appreciated.
