The pilot light on my hot water heater went out, and when I finally got it re-lit, it wouldn't quit heating and caused the pressure relief valve to release. I called Todd's Plumbing based on the great Yelp reviews. They were able to get a plumber out to work on it that day. They had to replace the thermocouple and pressure relief valve, which I was bummed about. Everything has worked great ever since though, and it was super affordable.
