We're are your bathrooms in the home.
How many vent pipes do you have when you look at your roof?
Yes excessive toilet paper and or backed up kids can lead to issues drainage wise.
Let us know
None of the bathroom is one above another. 3 bathrooms in 3 corners. 2 are upstairs and 1 is downstair.
i think there are 2 vent pipes.
Do you think a different toilet would help as these are builder toilets and house is approx 10 yrs old.
