Double kitchen sink with disposal on one side. Use the disposal daily. No problems for over 10 years. Lately, backup on the sink side happens 3-4 times a week. Almiost always very easy to plunge ond get working again. Took everything apart and no blockages or issues noted. Problem persists.
Could this be an air pressure problem? If so, what has changed and what do I need to do to take care of the problem? If not an air pressure problem what do I need to consider?
Would flushing the stack with the garden hose be helpful?
