Floors drains are required to have traps so there’s something else that drains into that would be the culprit. I knew someone else with this problem and discovered the hot water service overflow tray was actually plumbed up to drain into the laundry floor drain. The trap had dried out on the overflow tray and was causing the floor drain to smell as well.
Yes. Pour hot soapy water down that and any other drains near it. The trap has dried out.
I don’t think it has P trap installed. I already tried water , bleach etc but the smell is still there.
