I had the same problem. The anode on my WH is nearly gone after 2 seasons. What I learned is that it's very like due to "soft water". I usually fill my fresh water tank from home and it's softened water. The increase in sodium in the water gives the anode a life less than half of what it would be with "hard" water.

So where is the balance? You don't want water with high levels of calcium and magnesium clogging up the water system. Since the replacement anode is only about $15, I'm happy to just change it out every couple of years.
Also I have two filters in my water system and it's done nothing to save the anode from the sodium.

I picked up two anodes for my 10 gallon suburban water heater.
Suburban Water Heater Anode Rod Magnesium 2 PK 232767 | eBay

Price is $28 and no tax and free shipping


Don't forget you need a 1 1/16" socket to remove them.

We had a Sandpiper for 20 years....knew nothing about an anode in Suburban water heaters. The previous owner of our current unit had taken the anode out of this water heater before we bought it. Mostly gone, I (effortlessly) installed a new one. I'll be checking it's condition regularly now.

Just a thought about anode rods - I realize that we are talking about anode rods installed in RV units here, but has anyone ever given any thought about the anode rod installed in their home water heater or inspecting/replacing it?

The anode rod installed in your home water heater serves the same purpose as the one installed in your RV water heater and therefore corrodes (sacrifices) in the same manner.

I would wager that some homeowners are not aware that their water heater contains an anode rod.

I learned really fast that home water heaters contain anode rods after coming home and finding the bottom of my old water heater laying on the floor and water gushing out.

I now have a tankless water heater so I don't have to replace an anode rod any longer.

I change mine at home every 2 years

I looked at it late this summer while waiting for the paper work on the Lite to go thru.
Should be good for awhile.

Your city water comes from Lake Tahoe is that correct, Not any better anywhere. I use to live there and I bet yours would last 6 years..... WE aren't all that lucky.

I believe most home water heaters are glass lined and don't need the anodes. At least ours have all been glass lined.

I guess I had the cheap ones that weren't glass lined. I Googled the subject before I posted and what I found didn't specify glass or steel.

Anyway when we brought this house, I decided I didn't want a 40 gallon water bomb in my attic that could let go at anytime, so we got a tankless water heater that works great without an anode rood.
