I have a 2004 Cruiser 29RK that I live in. Last week I noticed a small lake on the floor when I got up in the morning. It had followed the counter tow kick all the way around from the Atwood 6 gallon water heater to the end of the counter that sticks out on the opposite side. I figured I must have a leaky fitting but all the connections were dry so I went ahead and ordered a tank before I even found the leak. I cut the strap holding the insulation halves together and lifted the top piece to find a tiny leak on the upper left rear. I was able to catch the water in a shallow pan for a few days while I waited for the new tank. Today I went down to the local UPS sort shed and picked up the tank and got to work. This isn't a highly technical job but a little hard to get to things at the back while reaching through cabinet drawer holes and having only one hand at a time in there. I finally got the unit out and on the bench only to discover it had a tiny leak about the same size on the front side next to the pressure relief valve port. Both were running down into the lower insulator piece and into my catch pan.
The new tank came complete with heating element and it's control switch. It also came with a new relief valve, gaskets and mounting plate retainer rings. I had to use a small cutting wheel on the dremel to get the retainer rings off. Putting the new ones on was a little tricky as well. I had to find a pipe driver in order to drive them on evenly.
Now for the question. This is an all aluminum tank and they say there is no need for an anode rod and so I don't have one. Should I have one anyway and will this slow down the tank corrosion? We have hard water here so that doesn't help. I see there are aluminum ones for Suburban, magnesium for Atwood and then there are Zinc ones. I read that the zinc rods last longer. Any thoughts on this?
I wasn't expecting this thing to spring a leak like this so was completely surprised. I'm just glad I was able to get a tank only for about half the price or less of a new unit.
Front leak discovered after removing unit from trailer.
Rear leak that I saw first by looking through the drawer opening.
Lots of crud build up on the element.
