In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
I was a job today ( I thought I was done with this) and saw two tubing brands that I suspected were not barrier tubings. I tried to see the name of the red one and I think Infloor was the brand? Just dunno.
The other was a a dull white with no markings. I know this is not a lot to go on. The heat source is bradford white water heaters and have failed twice in the last ten years. I know, great system. It's the tubing thing that's first though.
