Dometic 300 Series Toilet

[heagle52]

My Dometic 300 Series toilet in my 2013 Sabre FW is leaking between the base and the bowl. According to the Dometic website the toilet needs to be replaced. I'm a little reluctant in just replacing with the same brand and model without knowing what caused the leaking to start with. I began to notice the leaking a couple of months ago but thought it might be sweat forming since we were at the beach and hot and humid.

I would appreciate any feedback.

Yeah...that will seal it up.
Except it will just leak inside the lower base, collect and stink

If not going to call Dometic about a new replacement then replace it yourelf

300 Series......
The nice thing about these are the ease of replacing bowl seal and water supply assembly

BUT-----

Factory-sealed bowl-to-base assembly –
Unlike other Dometic foot-pedal toilets, the bowl and base of 300, 310, and 320 series toilets should not be separated for any reason.

Time for new toilet.

Pick your poison.
All have some quirk or other.

I think I'd replace the seals first and/or make sure it is tight. Worse case is you are out the time to replace the seal/tighten/clean. If that doesn't work, replace the whole thing.
