Winterizing Wet vs. Dry Opinions!

[Hondo65]

Just curious as to everyone's opinion on winterizing with RV antifreeze vs. air pressure. I realize that you still need to protect the P traps with antifreeze but seems easier to blow all the lines clear. I am definitely interested in hearing the pros / cons.

Thanks

It makes no difference. The end result if done even close to proper is exactly the same. I blow mine out because I have an air compressor.

Besides the P traps, don't forget the washing machine if you have one.

Many years ago I did the blowout on a SOB. Had to replace a Shower Faucet because a little water set in an elbow! Also think the Pink Stuff keeps the faucet washers wet!
So since then always use RV Antifreeze only takes less then 2 Gal for my 2955RL No Washer!

Depends on temps anticipated. If zero temps are going to happen, I would be more comfortable going the antifreeze route

I use 60 watt light bulbs with pink stuff in the P traps.

I've always done air, saves having to flush the lines in spring

I do both. Blow the water out then fill with anti-freeze; probably overkill; but never had a problem.

I do both. Doesn't take much longer and two gallons of anti freeze is cheap insurance.

Years ago when I got my first trailer I tried the air system, never again. The next spring I replaced almost all of the copper water line! I couldn't believe all the dips and valleys that held water. Since they went to plastic lines it's a much smother run, but I'm not taking any chances. Like scottz I do both, only about six bucks and ten minutes. Ever change out a toilet valve? Not fun.

Same here when we were in michigan.

I live in Norcal and blow the lines out then put in the pink stuff. When I am ready to go i hook up a hose and put the pink stuff back in the bottle for next year. Only use it 2 times than get some new. It never gets down to zero but its not uncommon to get to the low 20's

Like a few others have said, I do both. We live in a colder climate, so that combined with how much we paid for this rig, it’s worth my 1hr of time to protect it as best I can. I’d rather spend the 1hr up front than take the chance to spend multiple hours and $$$ next spring when I found out a little water settled in a line, valve or faucet. Just my $.02. That and $5 will get you a Starbucks coffee.

We put a different spin on the issue. We don't winterize the RV as we take it South, but what we do is winterize the House in Western NY. Blow all the water lines out, put the pink cool aid in the traps, toilets, and washer, call the electric company and have the power turned off. Been doing that for 6 years now with no issues and don't pay to heat an empty house.

I also do both.3 gallons of the pink stuff cheap at Walmart.

Since Keystone states both as options, they think that done right, blowing out the lines works even in cold states. My dealer uses the blow out method. Since I pull my RV out in January, I have to winterize multiple times, so antifreeze cost is a real consideration.

[tspoon]

I do both plus remove and empty p traps. I also cut out pipe going to washer hookups.(removed T and put in elbow). One gallon is all I need.
PS: don't wait to long to buy the pink stuff.Stores sell out and whoever has some raises their price.

[tspoon]

Don't forget to remove batts from remotes and fire alarm.(you wouldn't hear the alarm if it did go off).

I use air ... if you do it right, there will be no worries. Yes there will always be a little water left over in the lines here and there, but not the entire diameter of the water lines. The old copper lines were an issue, but today's plastic or PEX lines are very forgiving. If you blow thru all faucets, shower heads, stool, fresh water fill line, black tank rinse line, and outside faucets ... there will be no water in those to freeze. I do use about a quart of "pink stuff" in each P-Trap.

[CORattler]

I use the air method only. I do fill P traps with pink RV antifreeze.
I also blow out the lines to the washer connection even though I don't have a washer installed. I also pour pink RV antifreeze down the washer connection drain pipe. Never had a problem in all the years I've owned a RV. It does go to sub zero temperatures here occasionally.
