Anti-freeze in fresh water tank

[roadrat57]

My manual says to add 5 gallons of non-toxic antifreeze to fresh water tank. I have not seen or heard of this. I thought draining tank would be sufficient for winterization. My current knowledge is to never but anything in fresh water tank other than fresh water or fresh water and chlorine to sanitize/

I see no problem putting RV antifreeze in the fresh water tank. The spring fill with water and bleach plus another fill to rins is sufficient to flush out the antifreeze.

If the only way to install pink stuff is through the tank, then just draining and blowing out the lines might be the best way. Need to take a good look at you entire water system, and how to winterize. How water tank needs to be drained and bypassed.

I'll echo the winterizing kit option. Ours came with one, but I would have installed one if not! Incredibly easy to winterize that way - and doesn't put anything in the FW tank.

For your rig, 2000 Fleetwood Fiesta LX, the only way the manufacturer provided for getting antifreeze into the water lines is through the fresh water tank.

I would not put antifreeze in the fresh water tank for reasons others expressed, above. If blowing out the lines leaves you worried, then you should consider a third party winterizing kit. Such kits are easy to install and allow one to use the rev's water pump to pump antifreeze into the plumbing system without using the fresh water tank.

Do a search for "rv winterizing kits." Camco makes one that sells for around $12.

I'm a big proponent of reading and following manuals....but this advice maybe not so much.
No way am I putting 5 gallons of anti-freeze anywhere in our RV..
(but, I'm not familiar with your RV or how it is set up and plumbed.)

I think it is silly to add antifreeze to your fresh water tank. just install a winterizing kit, under $20, to pull AF directly from the bottle. or you can push it in thru the fresh water fill. on my TT it was virtually impossible to put the T connector before the pump so I put it after and force AF in thru a 12 volt bilge pump.

I agree.

[Johno02]

That is one way, but don't do it. Takes forever and lots of flushing to get all that stuff out of your system. Just drain it really well. You water will taste bad and foam forever after.

Is there a winterization package with a hose and valves that isolate the FW tank and allows pink stuff to be drawn from gallon containers? If not, putting pink stuff into the FW tank might be the only way to get pink stuff into the water lines.
What about a Water Heater bypass that keeps the pink stuff out of it?

Em, I don't I have a bottom drain and just dump the tank.
