Gary was awesome. I asked him to replace a broken anti-siphon valve on my pool auto-fill.
He gave me the option to buy my own parts, which I took, he gave me a very concise list which I managed to grab in about five minutes at home depot, came back, and very quickly, it was done. Not only that, but he added insulation without any comment around my piping to discourage it from happening in the future, and did a very nice clean job of it, at no charge.
