"Excellent co-ordination by the office. Lady set up a visit by her field worker - he showed up on time to evaluate the problem. He needed a gasket to fix the problem but had to get one at a supply store. Because he took longer to return then planned, he reduced the price by $30 and threw in a water pressure check as well. Oh, the gasket did fix the leak. Excellent job by all concerned."
