My pool had a problem with the plumbing. I contacted 4 places. One didn't service this area, two didn't bother even calling back and then there was Diamondback pools. Tom came out the same day after his scheduled work. He even dragged his delightful wife along since we lived between her work and their home. He diagnosed the problem and ordered the parts. We were up and running two days later and it is very important to run the equipment in Arizona in June. Well Done. A week later, the two that didn't call still haven't been heard from.
