Damn bud, that sucks. Presume you don't have a sump pump? I know it doesn't fix the problem now, but it does stop it happening next time and they're not stupid expensive to do - just need to dig a pit, wire it in, and install an exit pipe (or have someone do it). Also your insurance will likely give you a discount if you put one in.
And don't replace the carpet with more carpet. The only smart thing to use in a basement is LVP - it's not expensive at all these days and some of it looks and feels really high quality. Doesn't absorb water like laminate or carpet if it happens again, and it provides a waterproof barrier so that if you get a bit of damp below it won't permeate through and get absorbed into wood or soft furnishings.
i had a sump put in when the basement was first finished, luckily (or from what I understand this would've been a million times worse), it wasn't the sump pump that went but the ejector pump. The ejector pump is more pricy to replace, but whatever I'll take that over the absolute nightmare of damage that the sump pump going would've brought on. Just sucks that the carpet and some of the furnishings (the wooden shelves specifically) are going to have to go. I'm realllly hoping my tv stand is spared, and idgaf, i'll do anything not to toss the couch.
That's a fantastic idea with LVP (I had no idea what it was before your post), and most likely the route I'm going to go. Looks way cleaner than carpet anyway, and I saw some layouts that were fairly cost effective.
Just the whole hassle pisses me off and the fact that the ejector was put in, in October of 2019 so this shouldn't have happened. Here's hoping homeowners insurance comes through, that my initial hunch that the arcades/electronics/memorabilia isn't fucked with and that no mold is setting into the walls.
