    All Reviews for ProLine® Atmospheric Vent (400 series)
    Rated 5 out of 5 by from Great product and very reliable hot water heater. This is my second gas Hot water heater from State Waters. My first one purchased 12 years ago with 6 year warranty. I have been periodically flushing the tank and in 2021 replaced the anod rod, the original anod rod was in good condition. I stayed with the same because of company name, reliable and quality product ( no issue in 12 years) and the dimensions for the gas line and hot and cold water line did not need to be adjusted that was a plus. It was little pricey but worth it.
