we had a plugged dishwasher line and a leak under the sink on Saturday 6/8/2013 so we called plumbing masters out, they gave us a time of 10am -2pm the guy was here a little before 2 which was fine, however he did not seem to know very much about dishwashers as I had to instruct him on how to remove the dishwasher arm and how to reinstall a cover, (with me having eye surgery just 2 days prior) all he did was wire the drain hose up with a wire, he never even checked the leak, for the price of $157.70 I feel the cost was way too much
