De-winterizing my 335

[Krazymace]

During the walk thru on my new GT 335 I was shown the location of 4 valves to turn before adding antifreeze to my plumbing. Can hardly see the valves through the small opening provided. Assume all 4 valves had something to do with hot water bypass. Never seen more than one on any previous Rv. Anyway, I successfully completed winterization (I think), but now I need to de- winterize. We're heading South on Sunday. Assume I do everything in reverse of winterization i.e. Sanitize everything and then open the 4 valves. The owners manual is pretty much useless. Any feedback would be appreciated.

That is exactly what I've always done on my units. I normaly start with the cold water faucet furthest from the water source and open it untill all signs of pink stuff is gone, then move on to the next. Then.. I repeat that with the Hot water faucets. Don't forget the toilet, low point drains, ourside showers and Washer hookups f you have them.
It is only then will I open the bypass to the water heater.

You must be talking about these three plus the on by the pump that your turn to suck in the antifreeze.

That photo is with the black plastic panel removed. You don't have to remove it to turn the valves...just unscrew the white cap.

Those are the one's. Wasn't as easy as I had hoped. Fiddled around with the valves until I got running water at all the faucets. Problem is I filled my hot water tank and didn't want to at this point. Should all the valves be open when in use?

[davel1971]

during normal usage, the valve in the crossover tube should be the only one closed. Prevents mixing hot and cold water

[Krazymace]

Great information. Thanks gentlemen.

[Krazymace]

Which one's should be open/closed when I winterize? Assume just the opposite??

[alparmer]

For winterizing, set the valves just like the diagram. As you can see, water will not enter the water heater. You are basically blocking the in and out from the water heater and opening a line in between the two. For using the water heater, open the in and out to the tank and close the in between so that cold and hot water don't mix. It sound complicated at first, but you'll get used to it.

Thanks Al. I printed the diagram and your message. Will keep with my owners manuals.

Great pic and diagram!

Mine only has one valve. Never had an rv like that, still not sure how 1 valve can bypass the water heater ?????

With the use of check valves:

Thanks al now it makes sense

[alparmer]

No problem. I originally thought I had the one valve system, as I was told by the salesman. Come to find out, I had the three valve system.

One comment on de-winterizing. Make sure you get all the pink stuff out of your lines BEFORE you turn the hot water bypass off. I found that if you don't, you will get foamy hot water for a long time before it finally dilutes the residual antifreeze to where it doesn't react with the anode.
