Laundry and Kitchen are located right next to each other. When I do the laundry, some water from the washer comes out of the sink. I have the double sink type, water comes out on the side of the sink that does not has food grinder. This problem is recurring even after we cleaned or unclogged the drain. Could it be the vent pipe needs unclogging? If so, is this something we can do ourselves?

Also, we have a brand new food grinder, also the water on this side of the sink drains very slowly. I called the sink manufacturer, they say grinder should not create this problem, they recommend cleaning the drainage. We do not have dishwasher.

Are these prblems caused by clogged drain or vent pipe? Thanks.
