I replaced a garbage disposal 1/2 hp, Insinkerator Badger 5) under a double-sink. I would like some help determining how to prevent water backed up over other sink when in use.
With the stronger disposal (1/2hp vs. old 1/3hp), the water could not drain to the main pipe (through P-trap) and some popped up other sink. When I removed the Air Admittance Valve, problem went away.
How can I fix this problem? Your assistance is greatly appreciated.
