White scale in Hot water heater - what to do?

[LairdT]

I just winterized the Nitro (37 degrees last night here in Montana) and when I pulled the anode out of the water heater white scale started coming out with the water. The scale was rounded like the outside of the anode and there was quite a bit of it. Didn't get it all out and not sure how I would. Do I need to flush the tank before using the rig again? Why would there be so much build up after only 3 months use? - 3 months in Florida... granted but I would love to find a way to lessen the formation in the future.

Some people use something like this:

Its just mineral build up and normal. This is why you have an anode rod. It is the sacrificial lamb, not your heater. Just flush it out, I used a rubber clothes washer hose I had in the garage and cut it to about a foot or so and shove it in the hole and flush away.
