My water heater had not been drained in six years. Wedgeworth's plumbers drained it (the stuff that came out was just nasty), flushed it, and inspected it within less than an hour. It has made a world of difference in how fast hot water now gets from the water heater in the attic, of all places, to the rest of the house. Excellent service at an extremely reasonable price. I will have them come back next year and do the same thing!
