After running errands on Sunday, we came home to hear this drilling noise coming from the other side of one of our walls. The water heater's pressure and temperature valve was spinning like Linda Blair's head and draining a good amount of water. After calling a few plumbers via Angie's List or Google and Yelp!, we found two services that weren't closed and who we were able to leave messages for. This guy was the first to call back (yay Yelp!) and it wasn't too long after leaving the voicemail. He was able to diagnose the potential problem over the phone and give me an estimate. He was able to get to our place within the hour. After checking things out, he found the main problem to be more than the valve (water pressure from the house was dangerously high). He had no problem walking my husband and I through what he was doing or explaining things we didn't understand. He gave us an updated estimate on the spot before needing to run to Lowe's to pick up some extra parts he needed for the job.
I can't recommend this company strongly enough. The customer service was excellent. The work was thorough, done in a timely manner, and appears to be well done. For a day when it appeared that finding an open plumber was not going to happen, we ended up finding a fantastic company. We allowed them to put a sticker on out water heater so now we'll never lose their number.
