My bathroom sink was draining slowly so I plunged it and gunk came out and it smelled really bad. Occasionally since then when I first turn on the water in my sink I get a sulfur smell from the drain. Any idea on what is causing this? Since I use the sink twice a day the trap is always full of water so I do not imagine the sewage smell backing up.
Should I try Drain-o?
Thanks!!
