dewinterizing a small travel trailer

I have never dewinterized a rv before and have watched many videos on you tube. Doesnt seem too bad. I have two questions:
1. All these videos seem to drain eveything from antifreze to bleach water on the ground. Is this legal and would it be better to turn fuacets on in order to fill gray tank and drain at sewer dump.
2, i think there may be some antifreze in fresh water tank. Some one said never do this.will the rinsing and draining remove the antifreeze?

Thank you

The antifreeze should go into the grey tank and be dumped in the proper dump station / sewer.

RV antifreeze is not toxic and should not hurt the environment,

There should not be any antifreeze in the fresh water tank unless some one accidentally put it there or there is an issue with the water pump.

Lots of folks will likely chime in but we need a little more info.
Where is the trailer parked??
Is it at home where you have city water available?
Is it at a storage lot with/without city water available?

If you think there is RV antifreeze in the fresh water tank, put a bucket under the fresh tank drain and open the drain to see.



If you have city water available I'd connect a hose and open faucets until the pink is flushed out.
Same for the shower and toilet.
Afterwards you can drain your tanks at an RV dump station or use a bucket and carry in the house and dump in the john. If you're carrying to the toilet in your house just dump the gray tank. Leaving a little in the black tank until you reach an RV dump station on the road or in a camp ground is fine.

You can disconnect the city water and put some into your fresh tank.
Turn on the water pump and open a faucet to test the pump and flush it.

I'm sure others are typing as I write this so I'll leave it at this for now.
Good Luck!

I was going to stay at campground and do it there. Do you think I should also sanitize tank and lines. Water tank is in bypass mode right now so that should be alright???

dewinterizing a small travel trailer

I made an attachment for the end of my air compressor hose and use air to winterize my rv. I used an old washer hose, hose clamp and air chuck. I pressure up too between 25 and 35 psi after hooking up to city water line and then start at furthest faucet and work my way around trailer opening and closing faucets. Less than ten minutes to include opening drain plug on water heater.

On my last trailer before I joined this group. I opened my low water drains and faucets in trl every time I left a campground. I don’t know why but I did. Then to winterize I just pulled plug on water heater. I figure if the water that was left in the line had room to expand it might freeze but it wouldn’t crack the line since it had room to expand. Leaving faucets open allows enough water water of them that won’t freeze either. It got down to 0 a few days with high in 20s no problems.

Antifreeze in the grey tank

When you winterize, the antifreeze will drain into the grey and black tanks. This is a good thing. It will keep your flush valves from freezing up. Never drain the black tank into the environment but it is perfectly okay to drain the antifreeze from the grey into the sewer. It is environmentally safe.

The bleach is safe as well. You use bleach in your kitchen and laundry.

May be bad for your lawn though. I always use a 5 gallon pail and dump it into the nearest sewer drain.

you can pump air in your lines with a small tire pump then open up your spigots and drain the antifreeze out to
