I'm really grateful for Scott's help with a bogus plumbing company, which I almost hired. (I wanted a tankless water heater to save on the price of gas. I heard the tankless variety would be more expensive than the usual 40-gallon kind.) After I canceled work from that company, I talked with Scott, who told me I got hold of a "wild card." He said any reputable plumber would know NOT to vent a tankless model up a chimney, since the acidic fumes would destroy it in 10 years. I scheduled a visit for an estimate. Shortly afterward, I found a voicemail from "John the plumber," of the bogus company, who said there was a problem in that his company had already "pulled" and paid for a permit for work in my house. He wanted to be reimbursed for the cost. It was after 5pm, but I called Scott's number back, got his voicemail, and left a message wondering if said license could be transferred to HIS company. The next morning, Scott told me he had called my city's permit section and found that NO permit had been issued for my address. Also, he could not find a plumbing license for the company in the state directory. Scott, the owner and president, came to my house to get a look at my basement layout. We selected a location for the unit, farther from where I had expected it. It had to be mounted on an outside wall near an electrical outlet, which gave the necessary spark to the gas. The only thing that disappointed me slightly was that if I paid by credit card, he'd have to mark up the bill by the amount that the card company charged HIS company (3.5%). (Sure, my card gives me "cash back," but only 1%.) So, we agreed that I could pay by check, POST DATED (to give me time to get funds into my account). WHAP's crew was 2 young men, Kyle and Jordan, who arrived shortly before 10am. They turned the water off for a short while. At first, the shut off was going to be longer, but I asked if there was way to get some water to the front water faucet and the toilet (for a separate crew of a company adding insulation). They said they could get the water back on in one hour, which they did. They added pipe to reach the wall (expected) and a modern valve shut-off right after the water meter (unexpected but welcome) for an extra $50. The water heater is slightly larger than a big bread box! It's quiet, although not as quiet as a regular tank model. Something I did NOT expect was the smell of oil in the hot water (like 3-in-1 Oil). I called Scott about this, and he seemed baffled by this. He did not always return my phone calls on this matter. Yet, he did come to my house one evening with his step-daughter, who had a better "sniffer" than his. She couldn't smell anything. Scott did express willingness to split the cost of a water analysis if the problem persisted. He was confident that it would disappear in time. Turned out he was right (about 2 months).
