Toilet Flange repair or Change

I have a damaged toilet flange in my T2753 (2002). The toilet bolts holes are just not usable anymore.
The flange has already been turned 90 degrees to use the 2 alternate holes.. I can turn it back to the previus position as one of the bolt hole is OK, but would prefer to change it.
Does someone know how this is coupled to the tank? As it is turning, I assume it is not welded or glued. I tried to pry it out, but it did not come out.

Thanks

Hi Alain,

Any chance of a picture of what your existing flange looks like?

There are a few types and I do not know which your camper has to help better.

The pics may also help to try and understand why this is breaking. Has this been the first time for you and the other issues with the prior owner?

Something must not right for this to keep breaking.

John

Hi John, i will take pictures next time I am at the camping site. It looks like a 4x3 regular ABS toilet flange. I changed the donut seal last fall because I had bad smell and I probably overtighten the bolts, or the seal was too big for the model and the compression broke the flange during winter.

If it turns, it's probably threaded into a flange on top of the tank. Just spin it out. Some were just pushed into a rubber flange on top of the tank with a bit of silicone sealer. Others were glued in, but I doubt yours is if it turns.

How do I determine what size flange to buy for my 1981 Sunline and where do I get one?

I'm not totally sure what Sunline installed in 1981, but try this. Measure the OD of your current toilet floor flange. Odds are favorable, it might still be the standard home-sized floor flange size.

BUT, RV's often has a 3" threaded female floor flange. This allows a 3" ABS plastic pipe nipple to be screwed and glued into the floor flange to then screw into the black tank. Most home floor flanges at not thread, they are slipped on, and then an ABS cement bond is used on them.

See if your local Lowes has this. Or another lumber yard/plumbing supply store. Or a mobile home supply store
https://www.lowes.com/pd/Road-Home-F...ion/1002751984

Then you need to find a 3" ABS plastic pipe nipple the length of what is in your camper. NIBCO is one company that makes them. This is just one hit on the web for a place that sells them
https://www.davecarter.com/2527836/p...nibco-5829-3x3

You use ABS cement to bond the nipple to the floor flange. Look for ABS cement in the lumber plumbing area

I use Teflon pipe paste (pipe dope) on the treads screwed into the black tank

I'm assuming your toilet floor flange looks like this. If it does not, then post pics of what you have and we can try an help better






Here is how many of them come out of the tank, or at least the newer campers. Read to the end for good pics of the process

Hope this helps and let us know how you make out

John
