    It doesn’t matter how old your RV is, this needs to be done. My RV is a year old. The first time I did this, I had two wire nuts, a dozen 1/2” long stripped off wire insulation pieces and a hand full of aluminum shavings come out of the water heater. You never know what’s in there. Do it!!

    Son has an FR-3 one year old small class A that had lots of particulate buildup inside the toilet valve inlet line screen. The heater does not feed hot water to the toilet, but he was told by servicing dealer in Lancaster, CA that the water heater tank was making white "schmutz" and that was what he was seeing. I don't buy that for a moment; I think the particulate is from manufacture shavings and holes drilled by a sharp drill creating a bunch of polypropylene "bits" floating around in the fresh water tank. Nice well-described process for cleaning out the hot water tank. We full-time in a 40' Holiday Rambler Endeavor and have never done this process - I will go fetch one of those probe-gizmos and get it done!! Thanks again Darren!

    I just open the kitchen hot water faucet - works just as good. Every time I have tried using the pressure valve it ends up leaking. Also, when filling once water comes out of the faucet you know all the air is out. Also use teflon tape.

    Protip: if you don't have a fancy spray thing, follow the first part of his instructions for draining it, then close it up and turn the city water back on to refill it. Leave the city water on and go back and do the drain process, but forget to do the pressure release valve. The force of the water coming out of the drain will launch the sediment debris all over you and in a 10 foot radius.

    Question for you: during a four week road trip in a class c rv where we were turning the water heater off while driving, but it was otherwise on and hot, two times, we had no cold water whatsoever at the faucets and shower. Never had that problem before, but it made for miserable showers, needless to say. The only possible solution that I could find online was that there is supposed to be an air gap at the top of the water heater tank that allows for expansion. The heater being on for so long, coupled with the bumps etc. from travelling could have dispersed, dissipated, or otherwise made the air bubble go away. This may have caused hot water to back flow into the water tank, hence the hot water coming out of the cold. During the trip, I occasionally drained off some of the water from the water heater to reintroduce the air gap. I have since added an accumulator just off of the water pump. Will this help with this hot water back flow, or is the accumulator too small to even matter? Should I add another accumulator right at the hot water heater?

    I just usually blast the water throughout the somewhat empty water heater until it starts coming out clean. I don't know that you can ever get it completely clean though. If you are back flushing the water heater every 6 months to every year you should have years and years of trouble free use from your water heater.

    That smell is not coming from the water heater. It's bacteria that is living/growing in your water lines. If you Google there is a recipe involving bleach. Don't remember what the ratios are but you basically fill your fresh water tank with a small bleach solution. Then run it through all of your lines one at a time and let that bleach sit in there. Then flush and fill everything with clear water and that usually does the trick.
