Glad it worked out for you.

The brass valve on the floor by the Truma is the drain valve. Close it for de-winterization. The water you see coming from underneath the van is from this valve. If you use heat when your van is winterized then leave this valve open during g wi get operation.

@@tomrosback3142 After de-winterization having closed brass valve, when I use the heating system for chilly nights (for example, during Fall season), is it still to be closed? (I am thinking the brass valve functioning as a pressure relief valve from heating)

Leave the valve closed until you winterize and drain the Truma tank. If you use heat in the winter after the van has been winterized then leave the valve open.

@@tomrosback3142 If I use heat in the Fall before the van is to be winterized for the coming winter, should I still keep the valve closed?

Yes

Sanitizing your water system is straightforward. I do it was part of de-winterizing but you can do it at any time. 1. Drain your fresh water tank and Truma. Bypass the Truma; valves in red and blue lines closed, valve in red/blue line open. Open the valve in the blue line coming from the fresh water tank. Add 1/2 cup of household bleach to 1 gallon of water. Close the fresh water tank drain and Truma drain calves. Start filling the fresh tank and when it’s about 1/2 full pour in the bleach mixture. Continue filling the fresh tank. Run the water pump and open each faucet and let the water run until you smell chlorine. Do this for both hot and cold, on each faucet. Turn off water pump and let sit for 12 hours. I let ours sit over night. Drain the fresh tank. Set the valves for normal; valves in red and blue lines open, valve between red and blue lines closed. Fill the fresh water, turn on the pump and run water through every faucet until you don’t smell chlorine anymore. Do this for both hot and cold water. That’s it.

Hi again! @@tomrosback3142 Thanks so much for the details. UPDATE! I followed the instructions closely though here's what happed. I Drained the Fresh Water Tank, and Truma (pulled the lever up in Truma Cab and watched 2 gals approx drain under van.) I turned OFF the following: Blue Fresh Water Valve, Blue Cold Water inlet Valve (mine not hidden), Red Hot Outlet Valve (vert one in the back left side of Truma cab) I then Closed that Truma Valve in cab since it had all drained out on ground. .I Opened the Red/Blue line (called the bypass I think, it had been closed for months). I filled the fresh tank (bleach solution as instructed). I ran Water Pump, Open faucets but NO WATER CAME OUT of any of them, (Fresh Tank is Full), Then I thought to myself, " How can any water get to a faucet if the Blue Fresh Water Valve in front of the Truma Cab is OFF? I ONLY opened the Fresh Water Valve, tried the faucets and water was flowing. I shut off the Water Pump, and left every sitting as it was and returned to the keyboard.....mystified, (scratching my head) wondering how I screwed up? Thx for being patient with me, Plan is to HIT PAUSE and get back to the drawing Board. TY Paul

My instructions were not 100% clear. Leave the valve from the fresh water tank open. Has to be open for water to get to the pump and the rest of the system. Everything Else is A-OK.

@@tomrosback3142 Yaaay! All Good Tom! It's a marathon, not a sprint! HA! So since I did run (bleached) Fresh Water thru all faucets (late) last night (after opening just that fresh valve) seems after sitting Over-Night I can now: Drain the Fresh Tank, Re-Set the Valves for normal (per your instructions) or as they were for normal flow, (Only Closed Valve remains the Red/Blue Bypass, and the Truma Drain of course.) (Finally) :) Fill the Fresh Water, Pump clean through till no chlorine smell for H & C. Seems like the only part that still had me wondering was that (vertical red water line) or 'Hot Water Outlet' from the TRUMA, since I had closed it during the process, what was that actually doing or preventing? while I was running bleach water thru all the faucets? Again Tom, thx for the detail and patience as we learn, FYI.....I've been following your posts since Feb 2023 as a wannabe, then Jennie and I took the plunge Sept 2023 (thx to Rex & Greg as well). I do what I can as a Newbie to pass things fwd as well, must always remember that 'Deer in the Headlights' phase as well continue to learn! Paul

You close the red valve to prevent bleach water (or if you are winterizing g, antifreeze) from entering the Truma via that path.

Sharon - you’ve got this! It gets easier every time.

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.

Susan, I’m glad it helped. Happy Trail! Tom

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.

Yes, I sanitize even a new system. You don’t know where the components have been prior to installation in your van.

Thor has moved a bunch of stuff around so I’m glad you found them. You can run the Truma empty, see my answer to your question.

Glad this video helped out. Happy Trails!

Yes - propane and battery switch on for heat or hot water. After dewinterization I run the stove for a few minutes just to make sure the propane is working before I start the Truma.

@@tomrosback3142 does that mean you can run the truma empty?

Yes - I do it all the time. Make sure you open the Truma drain valve before you run the Truma for heat. This keeps pressure in the tank from building when you use the heater.

@@tomrosback3142 oh great. I was worried about the water jacket buckling from not being cooled by the water around it.

So, why do you use the small heater if the Truma is functional?

You’ll do great! It gets easier every time, too. The Facebook group “Thor Sequence and Tellaro Owners and Wannabes” is a great place to get help. Highly recommended.

1 Oz of bleach per 8 gallons of water. Our tank is 24 gallons, so 3 Oz of bleach. I mix the bleach with a gallon of water first to make it easier to put in the tank.

@@tomrosback3142 Thank you very much!

Yes. The external propane port is after the regulator so is low pressure. No additional regulator required.

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.

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!

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.

Ted - glad you found the video helpful. Happy Trails!

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

The fittings are 1/2”. Check your filter - some have two male fittings, some have a male and a female fitting.

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.

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.

Thanks all. Join the ‘Sequence and Tellaro Owners and Wannabes’ Facebook group - lots of great info and helpful folks there.

With the valves in the red and blue lines closed to keep antifreeze out of the Truma, the open valve between the red and blue lines allows antifreeze to flow into all the hot water lines.

If you have power where you keep your van then you can run a small electric heater to keep the inside above freezing and the tank heaters to keep the outside tanks from freezing you won't ever need to winterize. That's ideal. We store our van where it gets to -20 F and we have no power, so we have to winterize.
