- Winterizing a 2020 Thor Tellaro/Sequence 20A/T B-van using RV antifreeze.
It will work for other models and model years, the valves and ports will be in different locations.
Materials required:
2’ length of 1/2” ID plastic tubing with a 1/2” male NPT barb fitting to fit the tubing. This is used to pump antifreeze into the pipes.
6” to 12” length of 1/2” ID plastic tubing with a female NPT fitting on each end. You can buy these premade at your local hardware store. This is used to bypass the water filter and housing.
Schrader to 3/4” male (garden hose) NPT adapter. This is used to blow out the City Fill line. You could also use an antifreeze pump.
Bicycle tire pump or tire inflator.
2 gallons of RV Antifreeze.
All this is available at a local hardware store.
Thor water system schematic and winterization guide - available in Thor owner’s resource website.
1. Drain the fresh, black and grey water tanks.
2. Open all the faucets and the low point drains and run the water pump to get as much water out of the lines as possible.
3. Drain the Truma (brass valve with a yellow handle).
4. Close the fresh water tank valve.
5. Close the valves near the Truma both blue and red.
6. Open the Truma bypass valve between the red and blue lines.
7. Remove and drain the water filter housing and replace it with the male-male 1/2” NPT hose.
8. Dry the filter, and store in a place that won’t freeze.
9. Use the 3/4” male to schrader valve and a bike pump or tire pump and pump air into the city fill and tank fill fittings. This will clear out any water in those lines. Alternately you can buy an antifreeze pump and use that.
9. Close all the faucets and low point drains.
10. Place one end of the 2’ hose in a container of antifreeze and connect the 1/2” NPT male to the female winterization port.
11. Turn on the water pump and open one of the faucets on hot. Run until you see antifreeze come out solid. Close faucet. Repeat for cold. Then repeat for all faucets and the toilet flusher. Finish with the low point drains.
12. Remove the hose from the winterization port and replace the male cap.
13. Empty the grey tank.
14. Add antifreeze to the black and grey tanks.
All the valves and winterization port are located under the rear seat in the A/AT.
In the L, the winterization port and fresh water tank valve are located under the passenger side bed behind an access panel. The other valves are located under the drivers side bed adjacent to the Truma.
Thanks-new van owner and this was super easy to follow and matched my van components!!! 🙂
Susan, I’m glad it helped. Happy Trail!
Tom
I looked at so many videos, very few specifically on this model were found (at least in my case...) , this one was by far the best and the simplest and the most reassuring. I knew NOTHING before I started, now I'm the Boss! Thank you Mr Rocback
Glad this video helped out.
Happy Trails!
Here is my annual THANK YOU for this video! Every year this process gets easier and quicker!
We have a Thor sequence 20 K Thank you for your videos. Had left the check valve on the Truma open and was freaking out as to why all this water was dumping under the van. My wife kept saying it’s probably something simple and of course she was right LOL now. So once again very Thankful for the videos
I am brand new to Winterizing my Thor-Tellaro-B 20K. I have look over several video's on this. But after watching yours, your unit is simular to my unit, and I give you many thanks. I think I can actually do this myself. I can't wait to try your way. Using the bike pump is a great idea. Thank you again.
Sharon - you’ve got this! It gets easier every time.
Thank you so much for this video. I have a Sequence 20L and you have saved a lot of hassle for me to understand this process.
Excellent! Happy trails
Thanks so much for doing this. As a newThor B Van owner I was worried about messing with the Truma system. Your step by step instructions will help. Thanks again.
Thanks all. Join the ‘Sequence and Tellaro Owners and Wannabes’ Facebook group - lots of great info and helpful folks there.
Many thanks Tom. I have slightly different van but your video worked for me. It is just refreshing to see a video that explains the process well. I looked at dewinterizing also. I got them on my thumb drive for reference.
Thanks Richard, I’m glad the video was helpful for you.

Thanks Richard, I’m glad the video was helpful for you.
Perfect for my 20A! Much appreciated, saved me loads of time.
Thx always for sharing your knowledge Tom!!!
thanks Tom!!
Glad the video was helpful.
Excellent video. Thanks so much Tom, you are a life saver!
Ted - glad you found the video helpful. Happy Trails!
Question please: why was there still clear water in your faucets if the fresh water tank should have been drained before putting in the anti-freeze? This video is very helpful! Thanks for making it!
With our van the back is a little higher than the front so there is still some water in the fresh tank after I drain it. I run the water pump and open the low point drains until very little water is coming out. Then I know I’ve cleared the lines and emptied the tank.
@@tomrosback3142 THANK YOU TOM! Would you please advise when we reverse the 5 valves that we opened and closed? Namely these: 1. CLOSE FRESH WATER TANK VALVE (closed would be perpendicular)
2. CLOSE COLD WATER INLET VALVE
3. CLOSE HOT WATER OUTLET VALVE
4. OPEN VALVE BYPASS LINE
5. OPEN BRASS TRUMA DRAIN VALVE
Do we reverse these positions as soon as it's winterized?
No, you leave the valves alone until you de-winterize.
@@tomrosback3142 Thanks so much Tom!!
Soooo helpful. Thank
Hi Tom. Great videos and thank you for your time. How do you deal with winterizing the lines for the freshwater tank?
Our van has a simple gravity feed for fresh tank fill. Nothing to Winterize there. Some newer vans have a port like the city fill one. After you’ve drained the fresh tank use the bicycle pump to clear that line, just like the city fill line.
Other than that, you’re good to go. A little water I the fresh tank is not a problem because it has plenty of room to expand when it freezes.
@@tomrosback3142 Thanks Tom. I have a Sequence 20L so gravity feed also. Thank you.
Great video! Thanks much.
Thanks! Please check the fittings on your water filter before purchasing a bypass hose. Newer models have different fittings than I describe on the video. Happy Trails!
@@tomrosback3142 Thank you for the reminder, Tom. I just bought a 2022 Tellaro 20AT and pickup tomorrow. I am new to RVing, so may have questions in the future.
@@mingshanli1093 - there is a lot of great information in the Facebook group ‘Thor Sequence and Tellaro Owners and Wannabes’ including checklists for checkout and pickup. Happy Trails.
Thanks for the great info!
Thanks!
Hi Tom, I have a question that is not related to winterizing. Have you used the exterior propane port? I wonder if a pressure regulator is needed to connect a propane stove/grill. Probably not, but just make sure. Thank you!
Yes. The external propane port is after the regulator so is low pressure. No additional regulator required.
I do have a question though...it seams by using this bypass valve to put antifreeze in that the antifreeze does not get into the section of blue hose that runs from the water tank to the shut off valve next to the place you put the antifreeze in. Am I correct on this or does it somehow go all the way around through that tube?
Linda - that’s a very astute observation. It is correct. We rely on the water pump to vacate the water in that line. By draining the tank and keeping the pump running, we can get most of the water out of that line. So far it has worked for three winters.
The alternative would be to pour some antifreeze in the fresh tank and have the pump run it through that line. I prefer not to do that, since the tank may pick up the antifreeze taste.
I’m trying to winterize my 2022 Thor Tellaro for the first time by myself. I’m to the antifreeze step and the antifreeze won’t go in when I turn on the water pump. What could I be doing wrong?
Get a funnel that fits in the end of the hose. Lift the hose as high as you can and pour the antifreeze into the funnel. Turn on the water pump.
If that doesn’t do it loosen the plumbing fitting on the output end of the water pump. Put a towel down to catch any drips.
Tom, can you provide a link or info for the water filter bypass fitting you used.
Hi David - best to remove the filter assembly and take it to a hardware store and tell them you want a hose with the same fittings as the water filter. I’ve found out that depending model and year the fittings may be different.
Hi Tom, do you close the truma drain valve when you pump the antifreeze? Or leave it open? Many thanks.
I close the valve after the Truma is drained.
@@tomrosback3142 Hi, Tom, nice video and great help! One question: How do you open the yellow valve of the Trauma? Up or forward? I found that both way worked but not sure which one is the "Right" way. Thanks!
Hi Tom, happy new year! I followed your video to winterize my Tellaro 20A, but the pump did not pump the antifreeze. The pump seemed running. Any idea? Thanks a lot!
Make sure the valve to the fresh water tank is closed. It is located to the left of the winterization port. Then try lifting the antifreeze bottle above the water pump. Please let me know if either worked.
@@tomrosback3142 neither works. the pump not working properly? it makes noise though.
@@mingshanli1093 - if you haven’t already opened one faucet, try that. If that does not work you’ll need to contact Thor for further assistance. Good luck!
@@tomrosback3142 Hi Tom, Thank you much for still thinking of me. I got it work. I think the problem was there was no liquid (water in the line, pump). I filled the tube (connect the winterizing port) with antifreeze and push into or close to the pump, then turned on the pump. It started to pump the antifreeze.
@@mingshanli1093 - that’s great news, I’m glad you were able to get it to work.
Class B newbie here. I was wondering instead of using the anti freeze, can I just pump all the water out (using both low point release/water pump and bicycle air pump as you suggested, great idea btw) and call the winterizing done? Thanks.
Lots of people use an air compressor to clear out the lines and winterize their rigs. The higher volume of air you get from a compressor pushes the remaining water out of the low spots in the plumbing. I’m not sure a bike pump will do it, and repairs can be difficult and expensive.
Are all fittings 1/2" hose or 1/2" pipe
The fittings are 1/2”. Check your filter - some have two male fittings, some have a male and a female fitting.
Show me low point drain on thur tellaro 2022 off position
Best to ask this question in the Thor Sequence and Tellaro Owners and Wannabes Facebook page. The location of the drains changes by year and model.
1st thing is my 2022 tellaro 20a is not female to female. Wish I had known that before I bought the wrong hose , also no low point drains anywhere on this thing
I understand other models/years have different connections. Best to look at what you have before heading to the hardware store. Or even take in the filter assembly.
Your van probably has low point drains, you’ll find them in the schematic package for your van on the Thor Owner’s resource website. I’m some models they are small pull up valves located on the floor under cabinets, etc.
Updated info on winterization can be found in the Tellaro and Sequence Owners and Wannabes Facebook group.
Your low point drains (1 hot, 1 cold) are in the same cabinet as the circuit board under the passenger side bed. They're super small and tough to get through as they're likely buried under the floorboard and the waxy paper used on the floor. It took a small knife and a flathead screw driver to get mine up and open
