Question:
What floor flange will fit a Thetford Aqua Magic Style II toilet?

Expert Reply:
Welcome back Gabriel. The correct replacement floor flange for your Thetford Aqua Magic Style II toilet is going to depend on how the flange that came with your 2023 Highland Ridge Open Range 5th Wheel is attached.
If your flange is glued to the 3" sewer pipe then you would need to cut it off and use item # 344633633, which has a hub end that can slip over the pipe. You would then glue it with some abs cement like # 3447530889.
If you need to add a bit more pipe to get up to the right height then you can use a 3" coupling hub like item # D50-2935 and some straight pipe sourced at your local hardware store. If you choose to install another one at the top you could then use item # 3446336347, which has a spigot end and will slip inside the hub like a straight pipe would. This narrows your drain a bit.
If you lucked out and have a screw-in flange then you'll need to the item # T05-0784 if the threads are on the outside of the pipe or item # 3446336343 if the threads are on the inside of the pipe.
The Replacement Closet Bolt Package Kit item # TH94MA will allow you to connect your Thetford Aqua Magic Style II toilet to one of the replacement flanges. It replaces the two closet bolts, two closet bolt nuts, and the closet flange seal.
