Hi Mike,
Is that tubing Polypropolene or copper?
If it is copper I'd like to get a follow up from you in a few years. There have been several horror stories of copper reacting with concrete in these slab heating system, when the copper is in direct contact with the concrete, they last about 5 years.
Out here in SoCal we used to direct bury our copper water lines, but because of the acidic soil we have, the copper was being eaten and we now have to wrap or sleeve all in-slab, or through-slab, copper lines.
