I have used DFP several times, including today. I called them at 7:30 AM; the guy was at my house by 8 AM. He was friendly, knowledgeable, and quickly took care of the immediate problem. At my request he checked the other toilets to verify that they were working okay, and he even fixed one that had always been problematic by installing a new ball-thingie (technical term): it's working great now. The price was fair, and I wouldn't hesitate to call them in again (especially Jamey). :)
