Drain in basement floor has metal plate about 6" down
I have a 1908 Bungalow and since I moved in I've known the basement floor drain doesn't drain well. I've only put a few inches of water in there and it did drain, but took a long time. I just went to look at it and there's a metal plate of some sort about 6 inches down. Would that have been put there to block the drain for some reason? Trying to figure out how to proceed.

Could it just be a cleanout plug that comes out somehow?

I cleaned out in there a lot more. It's definitely a metal piece and it appears there's no way it comes out. I don't even see where water might be supposed to drain out. Is it possible someone put this there to forever block the drain???

does the water completely drain out eventually? Kind of sounds like a bell trap... completely against code now, and if it doesn't drain well it probably won't without a jackhammer :hammer: it could be a cover someone made a long time ago, pictures would help us tell ya :thumbup:

It does gradually drain, but it looks like only because there's a very tiny hole in there that looks like corrosion of some sort, and not an intentional hole.

Here's a photo. About 6 inches down that hole is the "plate" I'm talking about. By that I just mean a flat metal piece that seems to block off the pipe.

not a bell trap, do you know if it drains to your sewer system? Might just be a hole under the concrete with no piping for it (kind of like a dry well)

Well, it doesn't drain and since it's blocked off I don't know how to even get a sense of where it goes. maybe nowhere? Seems odd they'd make a basement without a drain

If that was my drain, I'd either replace it or or get a bimetal hole saw and drill thru the center of the plate just to see what happens.
You could try to drop a magnet on it and see if it moves :icon_lol:

So, it could really just be a drain with no actual pipe, and it doesn't go anywhere? Weird.

Ok, is there any danger in drilling a whole through it?

If there's really no pipe in there it sounds like a big job to get one put in, right?

Some of the building drains in my area exit through the foundation wall above the floor, not under the slab. So these basements have small drywells under the floordrains or just outside the foundation.
If your building drain is under the floor and your really concerned about having a working floordrain in your basement, expose the building drain, cut in the appropriate fitting to pipe a new one.
As far as drilling it, I would, but thats me not you. You decide.
Try this. Take a peice of rebar or something and strike the plug. What happens?
