Came over to evaluate if I could have a washer line installed, and to see if mysterious loud noise from bathroom pipes could be solved. He was late - but messaged me before hand to let me know. It was rush hour on the Bay Bridge, so I was understanding. He was very polite, informative, and honest with what I could/couldn't do. He fixed the noise problem promptly, explained to me what to expect from the new valve, and signs to look for when water pressure is too high. All in all, a pleasurable experience given my circumstances, and easy to pay (accepts credit card).
