Replacing in-Ground Basement Floor Drain - Rotted Away

Help Please

This drain is used for the basement shower(everyday use), furnace, and the washer.

Where do I find the drain that disintegrated? Is there anything I should do to prevent this in the future? Better way to set this up?

THere is NOTHING in the photos that show "disintegration", so what makes you think it has occurred?

Are you even sure that "floor drain" is actually connected to the house drain system? I've encountered many "floor drain" things similar to yours that just dump
into the footing drainage gravel. Anyway, if replacement is necessary, you may be sure that modern plastic drain piping will never disintegrate.

You should also be aware that you can't just dump waste water, even gray water, into an open drain pit. All drains require a P trap. Maybe there are things we are not seeing in your photo, but you need to do more research than you have indicated here. A plumber on site may be wise.

The normal thing for that "floor sink" drain would be for it to have a "P" trap below it, already.

I don't know terminology of things so bear with me. The metal pan in this drain had been coming up in pieces cause our water contains a lot of rust. there is no ptrap to this drain only a buldge in the bottom of the hole below the exiting ceramic drain under the cement. I know it's connected to the house drain cause we replaced my soil stack a few years ago and dumped water in it to see where it flowed and went strait for the soil stack and then out towards the front of the house.....I'm guessing to the city sewer. There are spots around this square that are hollow...so with the metal pan falling apart and the hollow spots in the concrete....I wrote disintegrating. I'm a novice when it comes to this stuff, but I have learned a ton since owning this house. I thought someone would recommend where I can find this metal pan at a minimum cause I don't know where to look cause I can't find it on **** or craigslist. I must be using the wrong terminology.

In restaurants, we often use a floor sink made from cast iron with a porcelain coating. I would install a p-trap below while you are replacing it.

Or you could use a trap seal device
