State water heater with 10 year warranty broke down (valve fault) after just 1 year and 1 day. State customer service sucks and they do not pay for shipping or labor to replace the part. If you do not pay for 2-day or overnight shipping, they will ship ground and will sit on the part for up to 3 days before shipping it out. From reading the other reviews it appears this is just the beginning of our woes with this money pit.
