2017 Rockwood 2506 Strange Stuff in Water Heater Tank

Hello All,

The following question may apply to other new Rockwood Mini Lite models, I noticed my hot water was coming out cloudy looking, I just thought since it was a new trailer it may take a little while to clear up but it didn't.

When I brought the trailer home this past weekend I decided to empty the water heater tank as I've always done when I'm finished using the trailer for the summer.

When I removed the plug for the water heater tank I noticed that the plug is part of some type of metal rod that looks like a diode used on boat outboard motors to minimize electrolysis. I have had many travel trailers and I have never seen a water heater plug like that one.

My water heater tank was full of something that kind of looks like sand, no wonder my water was cloudy.

Does anyone know what the purpose of the plug with the rod is for.

Thank you
Jimmy C

Do a search for ANODE ROD. It's a sacrificial chunk of metal to keep the electrical/chemical/etc. reaction from consuming the interior walls of your tank.Surburban heaters generally have 'em... Atwood heaters generally don't.

Matt,

Thanks, although I've already flush it, I'll do it again using the product you suggested.

FWIW, home hot water heaters all come with an anode rod. Technically, they should be replaced periodically though few people actually check them. Once the sacrificial metal has been dissolved, the hot water heater starts degrading. Changing the anode in these circumstances will extend the life of the water heater.

Had problems with white save or ground up shell looking stuff. We are now flushing the tank after every other trip. And so far much better, no more plugged faucets, etc

That ground up shell looking stuff it's exactly what I had in mine tank. I'm not thrilled with the Suburban water heater but it's now flushed & clean with new anode rod.

Thanks
