How to make a kitchen sink drain faster. 1 vent for entire house. 1 toilet , 1 bathtub, 1 bathroom sink and 1 kitchen sink all to 1 vent. Older home of course. Any suggestions/

Someone would need to know the whole lay out of the plumbing now to be able to suggest something.
How big is the vent you have now?

If the sink doesn't gurgle, it may not be a venting issue, could just be a restriction. Might just need snaked to clear out the food particles and congealed grease.
