Okay but you shouldn't be pouring paint down into any drains, especially acrylic paint, which is microplastics incarnate. What you want to do is wipe up all the paint with towels and put them into the trash. Your paint water or gamisol or whatever should be soaked up into towels, then left to dry before putting into the trash.

This makes sure your sinks don't get clogged and it's better for the water system. The paint then goes someplace where other garbage is disposed of. Even better if your local management has special disposing services for this sort of thing.
