Question:

Hi Mark; we don't know all of the differences between those different models, and only the # DOM67FR remains available. All of the others have been discontinued. Dometic makes slight changes and upgrades over time but those typically aren't features you can use to identify a specific model.

I'm assuming you asked this because you want to know if the Replacement Water Valve for Dometic Pedal Flush RV Toilets # DOM93FR is the right part for your 310. What you can do is look at the sticker on the back which has the information to identify it. See the attached photo. It is probably too difficult to stick your head back there and see it but you can use your phone camera to snap a picture and find out which model you have.

If you have a different model that isn't listed let me know and I can check with Dometic to see what is available.

Hey Mark, were you able to check the sticker on the back of your Dometic 310 to confirm which model you have? Knowing that could help others figure out which water valve fits their toilet too. Your update could make it easier for the next person with the same question.
