Antifreeze - How much?

Hi guys,

First time winterizing my TT. I have a 2017 Shasta Revere and I live in Michigan. I had it winterized by the dealer last year and am doing it myself this year. I got the air adapter to blow out the lines and have successfully done all that (low point drained, holding tanks drained, water heater drained, by-pass valves on, and blowing out the water). I'm to the point where I need to put some antifreeze in the traps and in the holding tanks (I think). Two questions:

1. How much antifreeze do I need in each of the traps?
2. Do I need antifreeze in gray and black holding tanks at all?

Much appreciated!
Paul

With the lines blown out, are you planning on pumping anti freeze through them? I used a couple gallons pumping it through all my lines, faucets, shower heads, etc.... I take what's left in the jug and dump it into the p traps. I do not put any in my holding tanks, just make sure they're empty.

I had asked the same question a few weeks back.

I blow mine out three times after a small wait in between each time, low point and heater by passed and empty. Also filter removed and wiped dry. Run pump to make sure its empty. Then use about a gallon of AF in three traps and into both holding tanks to protect the drain lines/valves to keep the seals wet. No problems in 5 years.

Don't forget to pour a couple inches into the toilet bowl and leave it there over the winter so the seal/gasket doesn't dry out. After blowing out the lines I used 2 gallons in out 5er.

I usually use three to four gallons, depends on the trailer. RV antifreeze is cheaper than fixing a broken water line or valve. Blow out the system through the low point drains, remove the anode​ rod in the water heater, (I put a piece of stainless steel screen in the hole for the anode rod, to keep out the critters)

If you pump the AF through the lines, as you open each faucet, it will go into the traps and holding tanks anyways.

There isn't really a set amount to use. I used 3 gallons total but I have 4 sinks, 2 toilets, a shower/tub and an outside shower. Even then I still had some leftover that I just distributed among the drains.

I used a lot more last year to fill the water filter canister (we don't use the filter). This year I heard about a hack to fill up most of the space.






This year I would have used a lot less RV antifreeze if I had remembered to shut off the outdoor shower before turning on the pump.



I also didn't realize that RVAF had lubricating properties and have been using a separate (and expensive) drain lube for years. No more!

Make sure to take the labels (if it's paper) of the water bottle, the antifreeze will dissolve the labels and gum up the pump, had a friend do that. Pumps can get expensive.

I have a rule of having 3 gals on hand when I winterize. Easy to forget a low point drain, outside shower...forgetting to turn off and you dump some antifreeze in the driveway. I drain my black and grey the day before and leave valves open till I pump in antifreeze and that prevents the AF from becoming diluted too much when I pour it down the traps. What I don't use goes back into garage for next year.

Thanks for the tip! I'll add that to my dewinterizing steps.

All good points.
Just to add my $0.02....

I completely empty my holding tanks. And leave the valves in the open position over the winter.
I push the sewer cap on put don't turn it to lock it.

If there's any liquid in the holding tank and it freezes my valves or piping don't get damaged and with the cap lose it can always pop off if it does freeze.

And don't forget if you use your water pump to pump AF threw the system. Push the check valve on the city water inlet to allow AF to push out any water trapped in there.

I empty the tanks on my last trip, open the fresh water tank and low point drain and let them drain as I travel home. When I get home I drain the black/grey tanks into a bucket as some will work its way down into those tanks.
Then I blow out the lines as you did and put antifreeze in the lines with the pump.
After that I blow the antifreeze out into the sinks, shower and toilet.
This puts antifreeze in the traps and a little in the waste tanks. I use a total of just under 2 gallons.

We just winterized our Villa Estate 394 FKDS ... used about 2.5 gallons. We didn't do the blowout, just opened all of the faucets, shower, etc., hooked up the pump and started filling. I'm going to go back and add a little to the black water tank just to be safe, though. And yes, we made sure to empty it before we got started. :-)

I like the water bottle idea. Never thought of that.

Don't forget your black tank flush and your washer hook up if you have one.

Crap! After reading this thread I now realize that I forgot my shower lines when I blew out my lines. I tried to pump juice thru my lines last year with no luck. Pump would not pick up antifreeze from jug no matter which way I turned the valve. Guess I will have to drag out the compressor and blow out the shower lines when it stops raining.

Most newer RV's have water less traps and do not require antifreeze.
As far as adding to holding tanks, I usually get enough down the drain when filling the system waiting for the pink stuff to come out. That is if you blow out the water first and drain the tanks completely.
I just did my MH with one gallon of antifreeze.
