I just had a water heater installed. They wouldn't do any work unless I paid in advance and I signed papers stating that I was satisfied with the entire project. I signed, but later found that them asking for or accepting a certificate of completion to be against the law in Michigan. Being it is against the law, would that make the certificate invalid? I later found a dent and couldn't get it replaced because I signed saying I was satisfied. Plus they were suppose to do an in-home consultation, but did it over the phone, so I didn't know what model or brand I was buying. I was unknowingly taken advantage of, but I should have researched further before doing anything at all Thanks, Dixie Sansom sansom23@chartermi.net
Call the city inspector first.
Do not be distracted by the "acceptance" form. The only thing that matters is whether the work is accepted by the city inspector. If the inspector says that the work is okay, then it is okay. If the inspector says the work is NOT okay, he/she will make the contractor repair or replace the installation.
