Which toilet

This is not a "what caused it" or a "how do I fix this" question. I am in my summer place in a rural state park in Montana. The water pressure fluctuates. Water pressure fell below 40 psi and my bathroom flooded. I called Thetford and they said yes, that is what happens when water pressure drops below 40 psi. After you experienced water pressure below 35 or 40psi and the Thetford overflowed in your bathroom what toilet did you replace your otherwise fine and new Thetford with?
Thanks,
Steve

Dometic 320 for us. The 310 and 320 appear to be the defacto recommendations on the forum.

Unfortunately the Thetford will overflow the bowl with low or fluctuating water pressure. Of course it will also flood if the pressure is steady, high, varying or the shade of the moon.

My preference for a replacement is the 320. It is better sized for adults, particularly males.

Replaced the one in the old rig with a Dometic 310 (all that would fit) after getting a total replacement from Tetford and still having all the problems with the new one. Haven't replaced the one in the new rig yet, but it's on the list.

Ok, a consensus, good. I will buy the Dometic.
Thanks to all, Steve

One last suggestion - check both the 310 and 320. We liked the 320 as I believe it is slightly taller than the 310, but I may be incorrect on that. Dometic is clearly the better unit.
