Disinfect the fresh water system? 2026 Navion 24R

[HRYSER]

I am planning on disinfecting the fresh water system with a chlorine water mix, on my 2026 Navion 24R . For that I will remove the cartridge in the cold water line which is in the cabinet under the kitchen sink. As far as the Truma AquaGo instant water heater goes, am I correct that the water heater's water filter should also be removed? Or are there water bypass valves I should flip for this procedure? Are there other concerns regarding the hot water recirculation system I should be aware off?

Any other advice you might have is highly appreciated. Thank you kindly.

Since you have a very different and very new system, I recommend going direct to the manual for the most reliable info. It has lots of small details that many will not remember to tell you about!

Section 8 has lots of the info that will help to get it done right the first time!
The problem I find with going with what I remember on RV plumbing is that me missing one small item can cost me lots of time to fix a frozen pipe!

Thank you MO. Unfortunately, the Manual does not explain the bypass valves' location.

I would remove ALL carbon-based water filters, they will filter out chlorine and RV antifreeze coloring.
This video shows how to winterize your Truma.

You may have missed this?

Thanks again, MO. I'll try to locate these valves.

Best regards

I used this and it worked great.

I got a bit more time to take a better look at this today and found there may be a better way to locate them. Much depends on how we each want to think. Sometimes the book info is not enough if they have hidden things behind panels or such, so a picture may be a big help?
We have an "interactive parts catalog" online and while I hate it as a funky/skunky thing to move around in, it is also great! Does that even make sense?
Good and bad here:

Winnebago Cortona Portal

cortona.winnebago.com

digging down to your specific RV and type stuff you want to find like plumbing, you can get some great info at times. Be warned, it may also make you loose your mind as it does things for random reasons at times!
But what we can get! Since we find drans have tubes hanging out underneath, we can look at the floorline of the RV and stop those hanging down. One set in near the driver's side rear corner like so!

Two ways we can go on this to get mre info. If we know the name of the aprt we want to find, like valve, we can search the list at right for "valve" and it highlights in yellow on the drawing when we click the name!

What this shows if we scroll to zoom in and twist it around a bit, we can see there are overflow pipes for the tank as well as a drain valve to drain that fresh tank! Good stuff to keep in mind if you have thoughts about where we might need to add some heat on a cold day? So you may have a couple drain back in the left rear corner, but we want to look around for those two the book mentioned if we can't spot them easy? So do some searching the list for valves? If you keep clicking them on the list it makes them "flash" on the drawing or it may also zooom so much you have to back off to find WHERE??? FUNKY!

Forward a bit and still back from the water pump, more show up!
Hope it helps as having different ways to find things can do different things for us, at times!
I like to know where they hid the pipes as that can help sort out ways to open a cabinet door or such if it is going to be an extra cold night and I want to let a little more heat go into that space!

Good luck on the "learning curve"! Seems to be a steep climb every time I switch RV but Winnebago does seem to try harder than many other brands!

 

[HRYSER]

MO, this is simply amazing. Many thanks for the link. Yes, a learning curve is required, ha, ha. But it offers great "inside"! Is there a way to get back to the main screen without having to start the Corona Portal again followed by entering the coach's mfg-year and serial number?

Thanks again.

Not sure of how it might work on different computer setups. I use windows and just hit the back arrow to go back to the previus screen until I get where needed. Like if on water ssytem and want to go back to "plumbing" to look at drains, the back arrow gets me there. one more and it gets me back tot eh indext of different systems like interior, chassis, etc.
a different hint to know is that it doesn't always do the same thing twice! So if you get what I call a "line crawing instead of a "3D" type more like a picture, try hitting the control below the drawingto switch from 2D to 3D! Then there may be times when that control button may be hidden under other things! hitting the "parts list" button may rmove that list at right and thet can let you see the 2D/3D button. NOT the perfect system but nice if we can get where we want to see as it has super fine details. Thing like turning the inverter around to view the front of it, may let us spot a GFCI there which is hidden on the far end when some look at teh inverter hung in some compartment.
Not a perfect sytem but lots better than crawling around the RV-----especialy if it has snowed last night!!
Also good to find things you never knew you had? Things like the Truma interface?
I'm betting I would never know I HAD opne let alone where or what it looked like to find it!

OKAY! It's back there on that board inb the rear where a bunch of otheer unknown sets!
Also can show where isolated, hidden fuses and fuse holders may be found!
I hate it but love it??
