Remove/Replace RV Toilet Issue

MattTaylor · 01-30-2016, 05:49 AM

Hi Everyone,

I need to remove the toilet from our Sightseer and replace it with a Nature's Head composting toilet. As you can see from the photos I've removed the top part, but there is still a base with a flange. The composting toilet sits directly on the floor, so I either need to remove this base or build a platform to cover it so the new toilet has a flat surface to sit on.

I tried removing the screws from the flange and pulled up, gently, on the base but it appears to be connected via the down tube to the black tank. Is that the case? Not sure at this point. Maybe I should just plug the hole and build a wood platform over it?

Thanks for any help you can offer on this. The toilet is the last piece of our boondocking bliss puzzle, we launch July 1st, yeah!!!!

I should also mention that I have looked up the plumbing diagrams for the coach. No joy. The drawing does not show the base nor the attachment method or hardware.

I believe the down pipe plugs into the black tank with a rubber bushing.

Look at replacement black tank sites to see what I mean.

You should be able to pull the pipe out, if it is a straight down pipe, and cut it shorter then the floor.

Then you can cap it off below floor level, if there is enough room.

Some floor flanges and drops are glued into the piping to the black tank while others may have just a foam or rubber bushing that seals the pipe into the black tank.

Mine happens to be glued together.

I would suggest that you use a Dremel and cut the old flange out allowing you to remove the base and then evaluate the situation to see what's needed to install your new toilet.

Agree with Dr4Film our 03 Journey was a glue in. Cut the flange and remove the spacer and see what you have.

Thanks SO SO much for all the help!!

The info here gave me enough confidence to remove all the screws from the flange and wiggle the base & down tube. The tube came out of the black tank's receptacle rather easily, with just a wiggle and a twist. Didn't see any type of gasket at all, it was just a tight fit and was not glued. Awesome!!

I want to keep all of these pieces and parts, never know, we might want to sell it some day & the buyers might want a regular toilet. So I'm going to go to Lowes and get a short piece of pipe the same size and cap/plug, put that in and the deed is done, Wup Wup!!

Thanks again everyone!!

That flange is a two inch aftermarket riser added to raise the toilet height. I say it is an aftermarket item because I never found it offered as an option on the 2004 Sightseer brochure. My Sightseer came new with the riser but I think my Sightseer was ordered and the guy that ordered it had some dealer add-ons like the riser and Camco vent covers that did not come from the factory put on it.
I suspect the financing or something fell through because it was definitely brand new when I bought it.

There is a grommet in the top of the tank that the tube went through.
The grommet in my Warrior that I had before I bought my Sightseer had split and I had to replace it.

Clay L Looks like Winnebago used the spacer with the Aqua Magic 4 toilet up to 07-27-03 in the Sightseer 35N.

That explains it then. My 2004 was built in 2003 July as I recall. Thanks for the info.

Went to Lowes and found a 3 inch plug. I'm going to put the pipe back in place after cutting it a little lower than floor level, then install the plug. The composting toilet sits flat on the floor so I think it will cover the hole just fine. In the sink cabinet there I have access to the dump value bay, so all I have to do to run the vent tube is drill an access hole at the base of the cabinet at wall. 12 volt power is also in that bay so getting power to the fan will be easy also. This is working out great so far, thanks again for all the helpful info everyone.
