Surprise! This morning we woke up and no hot water! Trying to find someone to come over and check out our water heater. No luck so far, but have more numbers to try. The one good thing is I think that the heater is still under warranty but of course the labor isn't going to be and plumbers are expensive. Will find out later today if it is going to be a small or a big fix. In the mean time it's cold showers, thank heaven it is summer time.
