Chris came out the very same day we called. Instead of just going right at where we thought the problem was, he took some time to understand our house's whole configuration, and then he solved the problem at a site that was quite remote from where the problem seemed to be. This was a far cheaper fix than it would have been if a less-capable individual had tried to fix the problem by going straight at it, where it was manifesting. And, by doing it same-day, our general contractor could keep working. Then, Chris explained to us the organization of our house's plumbing system. That knowledge alone was worth the price. A nightmare situation was avoided, and it could not have gone better.
