    If you have a good manifold, you valve off the leaking loops. That won't fix them, but they won't leak any more.

    They usually burst where the are not encased in concrete. The tubing that is low in the slab has to take the expansion that the encased tubing cannot.
    You might try running hot water through the tubing and see if you can see the leaks with an IR camera. The Flir One does a nice job and is pretty inexpensive.
    You might only have 2 repairs to make.
