    8yrs of troubleReview by Steve
    Looking for a replacement after 8yrs ownership.
    Pilot issues caused for replacement of Thermocouple at 2year intervals.
    Today, found water at base. After inspection, Tank has slight leak.
    Problem with replacement, nothing is the same as this darn heater (Water connector sizes, vent sizes and relief valve location!)
    Stick with a more common brand, that you can replace in a jiffy.
    Looks like they knew it would last just past 6yrs.
    Our home is in temperate climate and supplied with softwater.
    Good luck,
