If you have concerns about the new system then call the manufacture express your concerns and ask to have thier rep come and look it over. Keep in mind if the rep comes he will also bring the installing comtractor with him
Thank you. I was hoping that someone here would help me with a contact at American Standard. At this point, I just want to chat with them on the phone about what happened and ask about what I should do next. Specifically I was hoping for something like, "Yeah, Bob at American Standard is a nice guy and here's his number..." I thought the manufacturer might be good to talk to, as they have to warranty it for the next 10 years.
As to the other questions, the original contractor and I are still working through the process.
