Fred,He is a down to earth person with whole lot of knowledge!! I had another plumber (Humphrey Plumbing Service) come in and do the water piping. And have had nothing but problems. The lack of quality. BUT......Now "Fred's Plumbing Service Inc." Came in, Spent Time And Energy in the RIGHT Direction!! He fixed the Lack of Quality of the last plumbing service!!! So I do understand QAULITY working with engineers! And By Far This Man's QUALITY Is Far And Above Any Plumbers And/Or Engineers I have worked with!!! SO THINK "Fred's Plumbing Service Inc." FOR QUALITY!!!!!! So if your having Plumbing Problems Call Fred!!!....................P.S.This is my first time working with a quality Plumber!!!!
