Question about Drain in Floor and Standing Water
I apologize in advance for not knowing the correct term for this drain. It's in the laundry room floor, in the bottom floor/basement of our split-level home.
After we moved into this house I realized the drain always had standing water in it, and that it made the whole house smell like damp ickiness. It's not a sewer smell, it's just watery and a little bit moldy-laundryish.
Because of this smell, I covered up the drain with a plastic saucer.
Last week our hot water heater sprang a leak, and the water didn't go down the drain because of that plastic saucer. So the water went under the wall to soak the carpet in the bedroom. Yes, I am kicking myself. It's a bad idea to block a drain. Duh.
Now that the saucer is off, though, that smell is back. I lifted the grate and there is, of course, standing water there.
My questions: is there supposed to be water there? If so, what can I do to make it not smell? If not, what is likely the problem? The home was inspected before we bought it and the inspection says nothing about that drain.
Big thanks for any advice!
