Chad in the plumbing department totally screwed up my order and really wasted my time. I have a natural gas water heater, he ordered it as electric. He had to ring up two different orders. Anyway, long story short the installation guy couldn't do the work for whatever reason. He was not very nice either. I had to wait 20 minutes when I returned the thing because they couldn't locate the water heater. Go with one of the local plumbing companies. They might cost more but are way more professional.
