We purchased a house recently and the small landry room has a drain in the floor that gives off a slight smell more like stale water that anything. When you look down there is some water in there below the two small plastic tubes that are sticking out of the side. One tube end looks bigger than other. Managed to clean out some old hair and lint, I think its just sticky old water that hasn't been flushed in a while. How do i reduce the smell, its not causing issues in the house but you can smell it from time to time if you stick your head in the room. Looks like there is lint and stuff in the water so i Was wondering if I should use a siphon to drain the water? Thanks for any tips.
