I had concerns about my 21 year old water heater so I called Fast Water Heater Co. I received a quote over the phone and they could install it immediately. I agreed and the installer came. He looked over my set up and with an additional $500 he could bring my up to code. He explained all he needed to do so I agreed. The job was done quickly and professionally. He answered all my questions. I figured it was well worth the additional cost. I am totally satisfied and I would recommend Fast to anyone. I can now stop worrying about my old water heater.
