Where were you able to rent the IR camera? |

To answer the various questions, I borrowed the camera from work. It's part of my "learning curve" of how to use it. Consider it a class in "How to use an IR camera for something practical".
The water all perculated out (even in SC clay). Nothing was coming to the surface anywhere. There was also no erosion in the area. It was nice working on a heated slab in my garage. I knelt down on it and it felt great. Too bad it's such an expensive way to heat the slab.
I did have to take quite a bit of care to get to "new" copper so the solder would take. Emory cloth wasn't enough. I had to use a file for most of it. The ground contact had corroded it quite a bit.
I'll be filing my "Plan B" records of how I was planning on routing new PEX inside the house. Something else will probably let go in the future.
Thanks for all the ideas and interest. |

kudos:1 | I think you would be surprised if you used a moisture meter on it. That area would have shown a greater moisture level the closer to the leak you measured. |

When you do the Pex, run 1/2" as a feed and then branch off 1/4" to the fixtures. Works great. |

1/4" to the fixtures is choking it down way too much IMO. |

Newtown, PA | It works very well for me. Besides, most fixtures are 1/4" fittings anyway, no? |

If it works for you fine. It doesn't work for me. There's a big difference in 1/4 (actually 1/8 id) for any distance and 3/8 (1/4 id) at the fixture itself.
Actually the above is for copper. I couldn't find any listing for 1/4 PEX. From their website:
PEX Tubing Technical Specifications and General Installation Recommendations

Newtown, PA | I keep thinking of everything as 1/4". Wherever I said 1/4 should be 3/8. |

That would only be true if you are talking about refrigeration tubing. Plumbing tubing is sized by ID as the chart you posted shows so 3/8" plumbing tubing has an ID of 3/8 but 3/8 refrigeration has an OD of 3/8". |

3/8" PEX has an od of .5" and id of .350
1/2" PEX has an od of .624 and an id of .475 not quite 1/2"
Last I heard PEX is plumbing piping. Above is from their web site. |
