Sorry I forgot my plumber's name (though I just got off phone with him). 5 star for good customer service.
Today is friday, and I needed to fix water heater. I was refered to Clark Kent by another nice plumber. They was quick at responsing and dispatching. Though it is after 5pm, they still dropped by. For some reason, the previous plumber already fixed the problem. So this guy inspected the whole place and insured me that everything is fine now. He didn't even charge me dispatch fee!!!!!! They will definately be my future water heater repair people.
