Topic: Rust in the hot water tank

Posted By: roadbandit on 08/10/09 07:37pm

I am the 2nd owner of a 2006 Palamino Puma that I bought last October(I don't know anything about the previous owners). I drained the hot water tank, winterized the unit, and anxiously awaited this camping season. (I have been an RV owner for 15 years).

After a couple of trips out, we now noticed that every time we heat the water in the tank, we get rust colored water out of the hot water faucet and it smells rusty. I have tried draining the tank and flushing it with a wand; I drain the tank after each trip and the problem is still there.

Has anyone had this problem before? Any suggestions on how to "clean" the tank?

Thanks.

Make of your water heater? Does it have an anode rod? If so have you changed it at all?

By the way, bottom of water heater tank is like a shallow dish (it is not flat) and if you do not rinse the crud out of the dish well it will cause ongoing issues. You can fill with a bleach / water concentration in proper mix ratio to sanitize but this will not get the gunk out of the bottom of the tank.

It may be just shot. Check the anode rod if there is one, otherwise, the takn may be a loss. If you have to replace it, get on that you can change the anode in and then make sure you change it every year or so.

I cleaned out the bottom of my water heater and got a lot of sediment out of it, I took a coated coat hanger and make a small loop on the end of it then put electrical tape over the end of the wire and gently scraped around in the bottom of the water heater.



There was a lot of buildup in there, I was getting pieces of the porcelin liner coming out as well (before I even used the coat hanger) so I know the life of mine is very limited and I plan on replacing it as soon as I can afford to. I replaced one in my previous TT and the best place for the $$$ I could find was Ebay.

Since Atwood water tanks are made of only aluminum, they don't need an anode rod (unless someone has "IMPROVED" them by adding a metal plug in place of the nylon one) and being all aluminum they do not rust. I would assume that if yours is rusting it's a Suburban and probably a Suburban without an anode rod. Electrolysis will eat a water tank that has dissimilar metals in it's construction, like a Suburban, unless it is protected by a functioning anode rod.
Good luck / Skip

Are You sure about a Porcelain Liner Lost One?

There is often a buildup of White Crud that looks like Hard Plastic and could be mistaken for Porcelain. It is caused by the Horrible hard water often found in the South Western States! This stuff often plugs the Anti backup valves as well! Usually the Anode on Suburban Heaters will show signs of this crud!

thanks everyone for the info on where to get a hot water tank cleaning wand. I was doing a search on "hot water tank cleaning wand" and was coming up with nothing. Then, with your help, I found lots of cleaning wands when I did the search using "tank saver flushing tool".

Unfortunetly for me I am sure, I wish it wasn't. The pieces I was getting out was blue chunks for the porcelin about half the size of a dime.

Thanks everyone for your comments. I did neglect to say we do have a Suburban Hot Water tank. We have always had Atwood Tanks. We were told about the anode rod and did replace it this past Spring.

We ended up having to replace the tank. We were lucky that our local RV dealer, Redwood RV, had a tank in stock and an opening in his schedule to replace the tank. He told us it appeared the old one had been dropped (probably during installation) because the outside protection material (it looks like styrofoam) was cracked. He thought that may have started the problem. The porcelain was breaking off and the steel tank was exposed to the water causing it to rust.
