Because water tends to “seeks its own level” wouldn’t it back up the toilet first (lower) than the top of the vent pipe?
IF your toilet ball is OPEN then yes the water will come up in the toilet. BUT, the same seal that keeps water IN the bowl after flushing also stops water from coming UP. besides, the VOLUME and PRESSURE of the water is greater than any small seal leak in the toilet. RV toilets are NOT plumbed like residential toilets. Doug
