We live in a 2 bath home, ranch style. The toilet and shower in the master are fine, as is the kitchen sink and the laundry room. In the main bath, my toilet won't drain, when plunged out it backs into the tub drain. Also, when I run the water in the tub, it makes the toilet bubble. Same thing when I run water in the hand sink. We are on city sewer, and I have looked through all 1000 of the questions. Is my line blocked somewhere under the house? Any and all help is greatly appreciated!

You have a partial blockage in the branch of the main bath. To clear this blockage you must snake out the branch from the lavatory vent on the roof.
Put out enough cable to reach the bend at the base and about 15 or 20 feet more. Since the blockage's downstream from the lavatory snaking from the vent should clear the line. Good luck, Tom
