Air Head Tejo - Out with the Flush

[Half Fast Hugo]

We finally decided to get rid of the flush toilet after much agonizing internal debates. I looked at all the various models and decided on the Air Head Tejo which doesn't have a urine bottle and dumps right into the black tank through the toilet flange with a supplied fitting. This version is not yet on there website so you will have to call if you want this specific version that has clearance to sit over the toilet flange. It is still possible to use a urine bottle behind the tank with some possible ingenuity as there is a quick disconnect for the urine line. I'll try and keep the pictures in somewhat of an order so you can see the progress but feel free to ask with any questions. This is on our 2021 Legacy Elite II.

If you're taking the plunge, the biggest hurdle you'll have is getting the old toilet flange out. It can be a pain but it will twist out with some lifting at the same time. The existing toilet flange will not work as it had too small of an internal diameter as the 3" waste pipe is glued on the outside of the male flange. You will need to swap out the toilet flange for a female flange that the pipe will fit inside which isn't a big deal nor is it costly. You will need to bevel the end of the pipe so that is slides fairly easily into the black tank. I also shortened it up a bit as it dropped down a few inches lower into the tank than seemed necessary. The supplied urine house fitting will be glued into the toilet flange facing the rear of the toilet and the hose will be connected to the urine outlet on the upper left rear.

Mounting the toilet is pretty much dictated by the toilet flange mounted to the floor. I kind of did it by feel and moving the toilet side to side and centering it along with a few rough measurements. It worked just fine. I put the toilet in place where I wanted it, slid the brackets into each side and penciled around them so I knew where to go back and drill holes for the brackets. I used six stainless steel #10 - 3/4" long screws to secure it. Be careful not to drill to deep and go through the top of the black tank! I drilled one hole for each bracket and test fit the toilet before finishing drilling and it worked just fine.

The biggest concern for me was venting. The Air Head has the fan at the exit point to the exterior so I wanted to be able to take advantage of that rather than having to install an inline fan or something of the sort. My first consideration was to vent into the existing vent pipe in the vanity but that was not recommended by Air Head and they had even mentioned that they had discussed that with Oliver at some point. My next consideration was through the front wall and into the propane box which would have been really easy as well. However, I did read a lot about that not being acceptable for a whole host of reasons. I did consider running it into the box with the hose continuing down underneath the trailer so it vented below the open box. After poking around inside the trailer. I opted to mount the fan housing below the gray and black lines underneath the forward seat of the dinette. The gray line comes off super easy and it was pretty simple area to get to both inside and outside of the trailer. The hose connects to the housing and loops around and through the left side bathroom wall which keeps the vent hose visibility to a minimum as well. As you'll see in the pictures, I haven't caulked it all in yet and buttoned it up but I had a couple people as if I was done yet so I though I would post where I'm at. I like that it vents underneath with minimal bends in the hose and it is towards the outside of the trailer so I don't believe fumes will be an issue.You can place the vent hose on either the center hole in the back or the hole in the right side. I opted for the back since the hose was going out the left side anyhow and it gave it more clearance for the internal mechanism of the toilet and less hose length. They have an inline screen that will also be used in a coupler behind the toilet. I also used a heat gun to give the hose a slight bend but be careful as if you let it get a little too hot it will separate at the corrugations.

 

 

 

All in all is was a pretty simple install once I figured out how I wanted to do it and had all the miscellaneous parts ready to go. Now for a test run in a few weeks!

Thanks for the details. As I’d mentioned on the FB group, this is the toilet we’ve been considering. I like how you vented it vs what I’d  talked about by tying into the black vent. 

How is the height compared to the OEM flush toilet! We’re both somewhat short. Don’t want legs dangling like a little kid.

The Tejo is about 19.5" tall so it is definitely a couple of inches taller than our stock flush toilet. Not sure what you have in yours but it was definitely higher than mine. A foot stool may be in order for comfort!
