Leo thanks for the advice. I have , over the years, done several houses on the side. I have a pretty good knowledge of residential plumbing products. Moving from commercial plumbing to residential is definetly a change but I think a pretty resonable one. I guess I'm just nervous about being able to get a customer base started. Thanks for the adnice though, I will make sure to familiarize my self with the products involved in the residential side of the industry.
