Winterize Geo Pro 15TB

[TopDog]

Hi all! We picked up a Geo Pro 15TB in the spring, and were hoping to get some camping in but due to health issues were limited to two trips, bummer. Looks like next year will be better but now looking to winterize. Was looking for YouTube videos but none for our small camper. My understanding is I pour it directly into shower with pump on and water miser off but I manged to mess that up and nothing came through the faucets. I did bypass the heater but forgot to put the outside cap on when the first gallon was poured in. Not sure if I have the water miser right and was wondering if anybody knows of a video for my unit. Thanks for any help.

This video is not too far off …

Note that the anti-freeze can be pulled in from the outside connection next

This video is also close …

Moved thread from the Welcome Mat section to the Plumbing, Water Systems and Fixtures sub-forum since the OP's post is strictly about Plumbing and Water Systems and not an introduction post.

I just did my 24 E Pro 15TB, super easy.

Drain your hot water tank

Open your low point drains, Open the all the faucets also then shut them and close the low point drains once done

Close off water heater valve and move valve on water pump to only antifreeze will now pump from outside. There are 2 valves to close off, hot and cold valves.

Open antifreeze inlet outside, it is on the opposite side of your city water inlet

I made a short piece of hose to screw onto the antifreeze inlet and had the tube go to the bottom of the antifreeze jug.

Now go in turn on pump then turn on each faucet hot and cold until pink stuff comes out then shut off, then do the same with the shower hot and cold, keep the miser off.

Next flush your toilet until pink stuff comes out, I let some go into the black tank and leave some in the bowl to cover the seal.

Go outside and hook up your shower and do the same for hot and cold, I use a bucket to spray into. Turn off once you see pink stuff. I then take that bucket and dump into the sink drain.

I pour a little in the sink drain also for the gray tank, your shower will also get some going into the gray tank. Seeing we have wet baths, I take the shower head out of the holder and point it down at the floor so I do not get the entire area covered in antifreeze.

Your done. I used 1 gallon for the full process. Then I used a little out of the second gallon to pour directly into the sink and toilet. Total job 1 1/4 gallons.

Obviously make sure your black and gray tanks were already empty and drain your fresh water tank also. If you used your shower miser by accident then use a bucket to catch that antifreeze that comes out.

Hope this helps.

Much appreciated.

Only thing I use antifreeze for is bathroom sink p-trap, and apparently one in the tub too. Oh, a bit in toilet to keep seal wet. Been using air compressor to blow lines for 6 years, no issues. Started doing it this way after buying camper and discovering no pink stuff in lines in Spring. Called dealer, "oh, we don't use antifreeze, we just blow lines." Good enough for me!

I generally blow my lines, too … if the weather permits in winter, we will go out for a weekend or perhaps a week in Florida … our last few campers were more complex to winterize … but our new 15TB seems to blow out really well … only one P-Trap on the kitchen sink … the shower looks like it uses a Hepvo straight into the gray tank … I accept that it’s a bit of a risk … the anti-freeze method is most common/proven

I thought mine had a Hepvo under bathtub too, but somebody on forum with E/Geopro (newer model) said it had a p-trap. As long as you are meticulous blowing lines, especially toilet flush valve, no risk really. Oh, and don't forget to remove strainer from water pump, and bump pump several times to spin water out of it. The strainer will hold water even blowing lines, because air blows right past top of it, like a built-in water filter canister.

Correction … so this morning my curiosity was piqued … while laying on my butt underneath my 15TB refrigerator … I could clearly see that I do indeed have a p-trap (not a Hepvo) under my shower drain … the trap extends below into an “overflow pan” under the shower floor … this will get two cups of anti-freeze for sure (as will my kitchen sink) … thanks to everyone who posted for dropping trail blazes for me

OK, thanks for reminder to put antifreeze in that drain. Last couple years I didn't thinking it was a HEPVO and got away with it. Fortunately open drain pipes have more room for expansion as ice forms than plumbing supply lines, but I'm not sure what sort of toll freezing and thawing would have on plastic parts over time.

I found out my kitchen sink has a Hepvo when I replaced the sink with a real sink instead of the airplane lavatory size sink it came with. Had to re-orient the Hepvo from vertical to horizontal to make it work.

FR confirmed this morning … definitely a p-trap under the 15TB shower

I wish they would make the magic book with all the diagrams publicly available

Hmmm, so maybe THAT'S why when I let a big full kitchen sink of water (I upgraded to a larger sink from the OEM joke sink) drain all at once, water came up in the bathtub. I thought maybe grey tank was too full. Maybe not. And yes, it would be wonderful to have diagrams like that available to owners.
