| Just saw your drawing now,,,how far from main is washer and how far kitchen??
Think would put 3 or 4 inch vent at your main and another 2" after kitch at least. Maybe the washer too,,,or use a Air admittance valve there if allowed by code
One thing is I would always use a 2" drain drop and trap on washer,,,lots of 1 1/2" out there but if gets plugged a little OR modern machines dump faster you get a wet floor,,,never saw a 2" wet a floor. Clean out plugs where ever you can get to,,,never get too many. Washers have dried soap deposits,,sinks have food settling,,,they WILL plug some day,,,easier it is to get to a clean out the less it will plug,,,Murphys little known law. (coat the plug threads with a never seize type goop,,,like silicone plumbers thread seal) | |
