    the I&O manual should have some guidance

    If it is a tank in tank design, those are a bit harder to drain and flush

    Some stainless indirects come with anode rods that need checking ocassionally

    It comes with down to what is in your water and how much water goes through the tank. Minerals, ions, forever chemicals😏, etc

    Hotter tank temperatures cause more mineral precipitation, 140F should be adequate for you needs and also bacteria prevention

    Replace the anode rod if your model uses one . A regular drain/flush of any solids is another if you model has a decent drain valve ..

    There was an error rendering this rich post.

    Hi, All of the above is good information. I'll add, check the relief valve yearly. From Watts website "Following installation, The valve lever MUST be operated AT LEAST ONCE A YEAR to ensure that the water-ways are
    clear." Very few people do this.😒

    Yours, Larry
