Why you need to replace the Anode Rod in your RV's Water Heater

How often do water heater anode rods usually need replacement?

What are the signs of the anode rod needing replacement?

ANSWER: Anode Rod as pictured on the top of this page are used on Suburban RV Water Heaters to Extend the life of the water heater by attracting corrosive elements in the water that could corrode the water heater tank.

The Anode Rod is part of the Suburban Water Heater's drain plug. It should be checked at least once a year and should be replaced when half of the rod has been corroded away.

If you wait to change the rod until it is totally corroded, you stand a chance of corrosive damage to the tank. Also, excess sediment from the Anode Rod can cause flow problems with your RV's fresh water system.

The video below explains how to replace the Anode Rod.

As the video states when you are replacing the Anode Rod it is also a good time to flush your RV's Water Heater to get rid of any Sediment etc.

I hope this information helps.

Happy RVing

Hi Jeff, it's great that your hot water is working great but you should at least check the condition of your anode rod. If you remove your drain plug in your hot water tank to drain it then your anode rod should be attached to your drain plug. They are fairly inexpensive to replace and might save you from an expensive hot water tank replacement in the future. You should also check your hot water tank's pressure relief valve and make sure that's operable by lifting the little lever on the top of it and then releasing it to make sure it goes back in place! Do this before turning on your hot water on as doing it when the water has heated could get you scalded!! Also if the valve malfunctions when you try this then water will leak from it when you fill your tank but at least your tank will not blow up if it malfunctions! They are screwed into your tank and can be bought at any hardware store! Good luck!

Water heater anode rod 15 years old
by: Jeff Ellis

Just read about replacing the anode rod. When we had our new water heater put in in 2006, no one explained that I needed to replace it.

It's now approx 14 yrs old. Is it too late? Do I need to replace the water heater?

Every once in a while we do get an odor from our water. But I think that's from the cold water line and having to do with too much rain.

Anyway- at 14 years with no Anode rod replacement, should I just replace the whole thing, or is there a way to check if it's still OK?
Hot water works fine.
