Looking for some suggestions for a slow bathroom drain. It's been doing it for awhile. I've checked the P-Trap and its clear. This is a sink that the vent is under the sink. I've also used the Liquid Plumber Foaming Dain cleaner, we used to use that at our old home.... I have another drain with the same vent pipe configuration and that works just fine.

Thanks
