I am sorry Thomas but we do not have any replacement parts available for your Thetford Aria 19425 toilet. Really the only option I have for you is to replace it with the Thetford Aqua-Magic VI RV Toilet item #TH37SE. The Thetford item #TH37SE…

There are only a couple difference between the Dometic 320 and 510 RV toilets, which I'll go over for you; real quick, here are the part numbers for both: - Dometic 320 Full-Timer RV Toilet #DOM87FR - Dometic 510 Full-Timer RV Toilet #DOM29FR The…

Hey Niles, you are right that we do not have any replacement rinse release valves for the old model Thetford toilets. Your best option here will be to replace the whole toilet. The Thetford Aqua-Magic VI #TH37SE is what I recommend for replacing it.…

Hey Lendy, it sounds like you listed the outer diameter of the flange which is how you came up with 7 inches. This would work with that since the inner diameter would match what this was designed for.

...existing model is the retail model that comes with the plastic seat. The other difference is the color, since the # DOM57FR is white where your old toilet is considered a "bone" color. There is a slightly...

The lid for the Replacement Wooden Toilet Seat #DOM83FR that fits on a Dometic 310 RV Toilet #DOM57FR tapers to be narrower at the top of the lid. So it will be slightly narrower than the seat itself. I have included dimensions that show the widest…

The rear piece of the toilet sits just above the seat and seat cover so the overall height listed is from the ground to the top of this piece. The Dometic 311 Part-Timer RV Toilet - Low Profile - Round Bowl - Slow Close Lid - White Ceramic #DOM67FR,…

The main difference between the Dometic 310 Part-Timer RV Toilet #DOM57FR and the Dometic 311 Part-Timer RV Toilet #DOM67FR is that the 310 is standard height (20" tall) and the 311 is a low profile (15-1/2" tall). Both toilets will mount…

You can replace your current Dometic 300 with the Dometic Full-Timer RV Toilet #DOM27FR ( #DOM87FR for white) if you like the elongated bowl design or you can replace it with a Dometic Part-Timer RV Toilet #DOM57FR if you just want another standard…

The Dometic RV toilets like the part #DOM29FR that you referenced use the standard 1/2 inch thread size for the supply line like most toilets do.

Hey Aaron, the toilet you have now is the Thettford Aqua Magic Style II so the part #TH35SE that you referenced would be the correct replacement.

The Dometic 300 Toilet, #DOM64FR has a total length of 19-3/4" with a minimum distance from wall to center of 8-1/2". The Dometic 320, #DOM87FR is overall length of 22" with a minimum distance from wall to center of 11". If you…
