Fantastic! A plumber came last week who was a blithering idiot...told me it "was not the valves" and to soak the shower head in vinegar overnight because I have "moderately hard water." I did, still leaked! Kevin from Walt's Plumbing came the same afternoon that I called (fantastic!!) and diagnosed the problem correctly as the valves and replaced both for 2 shower heads. Problem fixed! We talked about adding a heat pump for hot water and he was so knowledgeable and explained so well I am having him do that. We also talked about water softeners and he said it would be very difficult and expensive because of the layout of the irrigation, so I won't do that. By the way the phone number shown on his listing on Angie's List is wrong, from their old office. Correct phone # is 559-299-4189.
