Last Fall when I winterized for the first time, I screwed up big time! I drained my water heater and replaced my anode rod. I noticed a lot of crud coming out of heater so I flushed out the heater with a garden hose, BIG MISTAKE!
I didn't open up the bypass valve first to isolate my water heater. Crud traveled thruout the lines and plugged up screens in every sink, toilet, shower. OOPS! Hope this keeps you from making same mistake that takes hours to fix.

What are you referring to as the "drain plug"? If it's a plastic plug on your WH, then you have an Atwood and don't have or need an anode rod.

Compressed air can be very dangerous, much more so than pressurized water. It is far safer to bypass the water heater when blowing out the water lines.

Always drain and bypass WT before using air.

I never air blow. Even with the correct air pressure i've seen water tubing connection loosen up and even unhooking. They don't build them like they use to .

Rather have air leaks then find the water puddle, have found both ways. These homes are Mobil and all the shaking and bouncing will loosen up mechanical connections. I check for new leaks every spring.....well every time I turn on the water. Also shut it off when leaving camp. As for the isolate the WH do it. If it is empty of water it just becomes a air compressor receiver and can take forever to blow down. I use air then pink stuff sucked it to the pump to the kitchen sink, pump is right below, so I know when water is completely out of pump and filter, then pump it to the toilet to protect that valve. One drop of water in that valve will break it. Rest of the Gal into the traps and done. Just had our 1st frost This morning but we are going out next weekend for the final trip of the year so our 2 small oil heaters into the rig today and it should be good for another week.
Happy camping.

Just attended a seminar last weekend on winterizing RV/TT's; the techs (who winterize literally hundreds of them every fall and "de-winterize" them in several months later) explained that using low-pressure air (per the manual instructions... usually ~35 psi maximum) is safe, but to consider that a form of "insurance". Draining, blowing out, and instilling the proper RV anti-freeze to the system (again, per the manufacturer's instructions) is the only way to help prevent problems later on.

Here is a link to a good explanation of the types of anti-freeze:
http://mainecamperdealer.com/what-yo...v-anti-freeze/

Another consideration that I was previously not aware of is that the Propolene Glycol anti-freeze is far easier to clear from the system; the ethanol based stuff will require many hours and gallons of water to get rid of the nasty taste and smell.

The ethanol stuff will KILL you And it doesn't take a lot. That's why you NEVER use it in an RV. And that's why you're not allowed to flush your engine block to the ground anymore.

Isn’t ethanol the kind of alcohol in booze? I thought methanol was the dangerous stuff.

The most common forms of antifreeze for most of us is either Propylene Glycol or Ethylene Glycol, although methanol and gylcerol are also used.

PG is non-toxic and used for winterizing RV's, as well as in food preparation equipment.

EG is used in automobiles and other such machinery.

I'm unaware of ethanol being used in antifreeze, so I assumed the poster meant "ethylene."

My cheap 2.00/gallon RV antifreeze is ethanol based.

It easily takes twice as long to winterize.
I have always done what you described, draining the water heater via the drain plug first, except for leaving the bypass valve open. Perhaps the thought is that if you drain the water heater and then reseat the drain plug, then blow the system out with the bypass valve open, you'll get some water back in the water heater. I wouldn't think you'd get enough to matter (I never have in the past) but perhaps you could?

Always open the bypass valve when winterizing.
Photo is attached. Is this what you're talking about?

I've not had it in the past, but I can see how it could easily happen. I hadn't thought of that.

Something of which I'd not thought, and good advice. Looking at the photo I just posted, I don't see a filter, however. I'll look next time I'm at the trailer lot.

[edit: It occurred to me that you are not talking about a hose type filter, but the water line filter. My water line filter is hooked up between the city water supply faucet outdoors and the hose to the trailer. HOWEVER, I do leave it in the trailer after I remove it , so if it still has water in it, it may be done for. But I need to replace it next spring anyway, so perhaps it's not the issue that an internal one would be. At least I think that's what you're talking about. Thanks for the thought.]

Drain the how water heater by removing the anode rod or drain plug and opening the pop-off safety valve.
Granted. But I always remove the drain plug and drain the water heater before doing the air (I think, if I recall, the manual says to do it that way as well), in which case bypassing the water heater didn't seem that important.

Yes, I have a plastic plug, and yes, the manual that came with it says it is an Atwood. But I was totally unaware that you didn't have or need an anode rod -- though I did wonder why there was no plug for removing it. Why does an Atwood not need an anode rod?

By the way, apologies for suddenly posting several messages. I've been away from internet access for some time and just got back. And I do appreciate the good thoughts people are sharing.
