Movin' on up from the GTA to the Canadian Arctic
Trucked water and sewage is not the reason the toilet is getting plugged. Water pressure in the lines is dependent on the water pump. May have an undersized pump. Could be the waste line is smaller than it should be. Most likely reason the toilet gets plugged is someone is putting to much toilet paper in the toilet at once. If it is newer toilet it's probably the 1.5L water tank. Great for pee not so much for paper. The only thing trucked water and sewage affect is if it hasn't been done in awhile and either the water tank is empty or the sewage tank is full.
