John E Davies Posted September 27, 2016 Share Posted September 27, 2016 Found this, it indicated that the anode can look pretty darn scruffy and still be entirely serviceable. Just because it has some holes, don't toss it. They are not cheap.

dharmardr Posted September 27, 2016 Share Posted September 27, 2016 Thanks John, I did purchase another one but I am keeping it as a spare (after being your post) and will use it next year at winterization time.

Mainiac Posted October 31, 2016 Share Posted October 31, 2016 I have seen anodes last for years and years, it usually depends on the water in the heater.. Link to comment Share on other sites More sharing options...
John E Davies Posted August 29, 2019 Author Share Posted August 29, 2019 Bump for an old thread. I fixed a missing image.

Moderators SeaDawg Posted August 29, 2019 Moderators Share Posted August 29, 2019 When we had the Suburban, our anode lasted four or five years. I chalked it up to never using the heater on electricity, just gas. Maybe it was due also to filtered water. Idk. On boats, anodes (zincs) are usually replced when half eaten. Cheap insurance. Truly, if we still had a Suburban, I don't think I'd run one down as low as the suburban diagram shows, as most of us only drain that tank once a year, for winterization. For the $10 or so on Amazon, I'd replace it at around half. Just me. It IS very important to inspect the anode. Thanks for the reminder, John.

routlaw Posted August 30, 2019 Share Posted August 30, 2019 Good info John. Can't remember if I had the by pass valves off every year when winterizing though. Oh well. Legacy Elite II #70 Link to comment Share on other sites More sharing options...
Moderators topgun2 Posted August 30, 2019 Moderators Share Posted August 30, 2019 Routlaw - I'm sure that you would remember if you had the by-pass valve "off" or not. If you do not use the by-pass valve, you will be adding an additional 6 gallons of anti-freeze over the approximate 1.5 gallons that it takes otherwise. Bill p.s. of course I'm assuming that you are using anti-freeze versus other winterization methods. 2023 Ford F150 Lariat 3.5EB FX4 Max Towing, Max Payload, 2016 Oliver Elite II - Hull #117 "Twist" Near Asheville, NC Link to comment Share on other sites More sharing options...
routlaw Posted August 30, 2019 Share Posted August 30, 2019 Yep, that makes sense. I don't go through that much only about two gallons. Legacy Elite II #70 Link to comment Share on other sites More sharing options...
