Topic: Reuse RV Antifreeze?

Posted By: Gang-of-Wrights on 10/12/10 03:39pm

My father-in-law and I are debating the reuse of rv anti-freeze from year to year. I say that for the $16 to $24 to buy new, it is worth it. His position is why waste it when if you can reuse it. What are the thoughts of the forum?

Also, in the spring. How should I dispose of it?

I save the bottles and reuse mine, but I am well stingy. It doesn't take much effort to flush it from the faucets back into the bottle.

$16-$24?? How much anti-freeze are you using?? All you need is about 1-2 gallons. Every time you put it in it will become slightly diluted with the water left in the lines.. so how do you know when it is no longer able to withstand freezing?

I reuse mine for about two seasons, then discard and use new. We can hit -40F and ...knock on wood...have not had any problems. I do however try and get every last drop of H2O out of the tank and lines b/f I put in the antifreeze in an effort not to let it get to diluted.

Can't is correct if done right winterizing takes 2 gallons at the outside. It sells for less than 5 dollars a gallon. No matter how well you blow out or drain the lines there is a bit of water there to dilute the anti-freeze. Toss the old. I dump the old down the house or campground toilet.

He did ask how to get rid of old antifreeze. I'm not sure myself. I doubt that it is toxic so pooring it down a storm sewer would be ok I think. Let's see what others say about it.


Posted By: 4u2nv on 10/12/10 04:03pm

I reuse mine... I also have an antifreeze tester to check how good it is. I blow the lines out before adding the antifreeze so there isn't much in there for water. Come spring time I blow the antifreeze out back into the containers. Usually end up needing more when winter rolls around though so it's not all recycled.

That would be a NO... pouring it down a storm drain? I don't think you would want to be caught pouring anything down a storm drain.


Posted By: JN_B on 10/12/10 04:05pm

Just out of curiosity how would you get it out of the sink traps. I can garantee no matter how many times you flush your tanks there will always be some "remnants" left. Don't really want to store that **** anywhere. No pun intended.

You're average gallon of ice cream contains Rv Antifreeze. So guess what. It's safe for a human to consume. Down to the dump station it goes, if my body can handle it so can the environment.

No offense but If you're worried about saving $20-30/yr on RV Antifreeze you're probably involved in the wrong hobby.

Do you turn around and head the other direction if you encounter a headwind??

/rant.. I understand some people are "thrifty" but this seems excessive.

Why don't you just buy a compressor, and the proper fitting, remove the water pump and blow out the whole system. No need for Antifreeze.

I don't use antifreeze except in the traps and toilet, I blow my lines out and don't have to worry about it. Disposal is easy; it is biodegradable and non-toxic (you're using it in your Potable water lines), so, if you aren't going to recycle it next year, just flush your lines and let it go into your waste tanks for disposal the next time you dump your tanks.

I did know a guy, years ago, that recycled his... His test? He'd collect the used antifreeze in the spring and put it in his deep freeze at the house for the summer. If in the fall, it wasn't slushy or frozen, he re-used it. I thought it was kind of clever. I don't remember how many years he got out of the same batch of anitfreeze, but, it was more than a couple. Our temps rarely go below 0 around here and he figured if it didn't freeze in the freezer over the summer, it would certainly stand up to a night or two of 0 degrees.

Me, I just prefer blowing out the lines. Been doing it for years, but, that is just my personal preference.

Hi,

I live in a climate that requires me to winterize 5 to 7 times per winter season. I do reuse the anti freeze and find I can salvage 3/4 of it.

Here is what I do:

1. drain all tanks
2. set water heater bypass
3. blow the lines
4. suck up antifreeze and fill the lines
5. blow the lines again salvaging as much anti freeze as I can.

It works well for me.

Right now I can buy antifreeze for $2 to $3 a gallon around here. So $24 would get me 8 gallons minimum? Wow. Teach him how to bypass water heater and save 6 gallons minimum.

I use 2 or 3 gallons a year, so IMHO it isn't worth saving for $6 or so.

I let gray water tank empty into my lawn when dewinterizing.
I empty black water down toilet, into my septic system.
No troubles yet in over 20 years of doing that.

I just winterized mine tonight. It took about 1.75 gallons. I let what flows down the drains sit in the respective tanks through the winter. I will empty it when I visit the dump station the next time that I go camping in the spring. I don't reuse it either. For less than $10 it is pretty cheap insurance to put new stuff in every year.

On my 25 foot travel trailer with full bath and shower, I only use a little over a gallon.
I pay less than four dollars per gallon.

Stop filling the hot water tank, and you'll save 24 dollars

Thanks gang. I only used 3 gal. to winterize my TT. This was my first year as previously I had a pop-up and just blew out the lines. A new experience for me. It was actually easier than I thought it would be. I purchased the recommended 4-6 gallons and will return 3. At this point I'll still continue to buy new. Maybe I'll give my father-in-law my used to suppliment his recycling.

I use about 1 and 1/2 gallons of the pink stuff to winterize. In the spring (or whenever I want, used to to do it 4 or 3 times a winter) I just run it out on the ground. It ain't killed no grass yet. I heard you can drink the stuff, ain't never tried, but the grass don't seem to mind it a'tall.

I luckily don't have to go through this process because I live in moderate winter climate, but I can't imagine saving waste tank anti-freeze to use again. It's gotta be contaminated from the tanks and I wouldn't want to handle it, bottle it, or store it. Dump it and buy new stuff next year!

Or you can save the three extra gallons for next year. It doesn't go bad in just a few years.

I'm sure OP isn't talking about this, I hope! I save from year to year, but dump the used into the traps and tanks. Even if diluted it won't cause any problems there. Use new for the water lines, then save that in the spring.

Yeah, we are talking water line antifreeze recycling - not the antifreeze in the waste tank..


Posted By: weathershak on 10/13/10 08:03am

Since we winterize 6 or 7 times a year, I collect what I can from the low point drains and use that stuff for the holding tanks when we winter camp. I always pump in new when we are done with our trip. It is worth the average $24.00 per year and pays for itself the first trip out only paying off season CG rates.

Posted By: JayWalker2009 on 10/13/10 10:18am

I can't believe anyone would re-use it with it being so cheap. I wouldn't take the risk considering how important of a job rv antifreeze does...

3 gallons @ $3.50/gallon at TSC...not worth the effort to recapture and reuse it.

If the cost of storing something costs more than the cost of purchasing something, then it is a waste of money to store it.

The effort to recover it? The cost to store it (you paid for your house/shed, remember)? The risk of re-using it? A $6 investment each year in 2 new gallons seems like a really, really, really, really easy decision.

Hi Kwrhinspace,

Now take that 2 gallons and multiply by 7 times. Oops! It just got expensive.

Guess I'm not understanding some of these arguments. Not worth the effort? I hold the empty jug under the low point drain and turn the valve. Then do the other line. Not much effort involved. As to the "risk" of reusing, the previously used mostly goes into the black and grey tanks where there is plenty of room for expansion for any small amount of water that was left in the pipes with the af. I sincerely doubt that my tanks are bone dry even if I add a fresh new bottle. Not much risk there either, that I can see, and I just saved six bucks to spend on beer! I must be missing something here. Happy trails!

I worked for a local RV company and yes we did reuse antifreeze that was shipped in new units from the manufacturer in the freshwater systems, used strictly for drains and traps only, never to be run into freshwater plumbing.

But what's puzzling is how you can use more than 1 gallon of antifreeze. When I winterized units, I found that you blew out the lines, then pumped enough pink stuff to hit the farthest point in the RV. Then shut the pump off, then blow out the lines again. The antifreeze in the lines would push out into the sinks, working into the drains and toilet valve. Then split the remainder of the gallon (usually half a gallon or more) into all the traps and the toilet.

I find that if you want to recycle, go ahead, but it seems to be way too much work for what you really need.

Has anyone ever tried using an EVAC system to remove the water from the lines??

And then blowing the traps??
