We have 2 Dometic 8700 Masterflush toilets in our 2018 Ventana. Both toilets randomly drain all the water from the bowl after flushing. Note: we always use the setting that uses more water and is supposed to fill the bowl after flushing.
We talked to Dometic support and sent them a picture from the back of the toilet (see below). They told us that Newmar didn't install it correctly, that's why we have that problem. Something about the discharge hose sitting too low.
I was wondering if anybody with the same toilet who doesn't experience that problem could post a similar picture for us to compare.
Many thanks in advance,
