The facts have errors of common sense.

Drain the whole with the low point drains first by gravity. Thats why they are there.

Make sure you FW tank is empty as well.

Remove anode, water filter bypass HW tank, turn on winterizing valve

Then if you must use air with oil mixed in to pressure blow out your lines use 30 psi. 60 psi will blow the plastic facets apart.

I use antifreeze, pretty cheap insurance. use the big 2.5 gallon jug just to make sure!

Make sure you press in the city water spigot to get rid of any water there

Also crack open the HW tank to remove last bit of water on the other side of the valve

If you have a hose flusher on the Toilet run Antifreeze threw this as well.

Black tank rinse needs to be winterized as well, I find the vacuum breaker does a good job of draining the feed side. The other side drains on its own in my unit

Don't forget to make sure some antifreeze is sitting on the GW and BW tanks valves so they don't dry out

After winterizing boats I have owned over the years winterizing our very first RV was a piece of cake. I do not use an air compressor. Personal preference is to use antifreeze.

I drain the water out of the water heater, open the low point drains to drain water out of the lines and open the valve to drain the fresh water tank. When the water is drained I close the valves. Turn the handles to bypass the fresh water and hot water tanks.

I have a 5 gallon container I used for winterizing my previous boats. I put 4 gallons of antifreeze in it and put the siphon hose in it. I know 4 gallons is more than I need but when I use to pay anywhere from $250 to $300 a year to winterize my boat $10 for antifreeze is not so bad.

So I don't forget to winterize the outside shower I use that to pump antifreeze through the system. I connect the hose of the shower to the city water connection. I turn on the water pump and start opening all the faucets. Run antifreeze until comes out good and pink. The more antifreeze less diluted with water. I flush the toilet to run antifreeze through it.

I then go outside and connect the shower hose to the black water flush to get antifreeze there also. I then open the low point drains until antifreeze comes out. Close the valves again and turn the pump off. I pour what is left in drains and what is left I pour down the toilet leaving a little in the toilet to keep the seal lubricated.

My DW cleans the antifreeze out of the sinks and shower so they don't get stained. Done until next year.

Not sure about your pressure rating. Here's a cheap ball valve from the web. The only pressure relief device on an RV is set for 125 psi. Lots of folks would come home to wet carpet if fittings failed at 60psi.
● Thermoplastic design eliminates process and atmospheric corrosion.
● Pressure rated up to 150 psi, non-shock water at 73o F
● Meets ASTM dimensions for Socket (D-2466) &
Thread (D-2464 )
● Sch 40 wall thickness
● Bi-directional: can be installed in either direction.
● Individually Bar-coded

Or... an oil/water separator for piston compressors.

Here is a link to a video of winterizing my Sunseeker. Doing a travel trailer should be very similar. Hope it helps.

replacing antifreeze in traps

Just wondering if its needed to replace some of the pink stuff put in the traps during the winter. Does it evaporate out?? Dry out?? The RV is in a storage lot a few miles away. We blew out the lines and put antifreeze in the traps and toilet. Just wondered if it needed "refreshing" during the winter.

Thanks for the information.
