Jay's sewer line nightmare

I'm just going to be frank: flushing my toilet is a game of roulette right now. Every time I use water in any way, be it showering, doing the dishes, heck just washing my hands, it has the potential to flood my basement with sewage because there's an unknown issue with my plumbing underneath concrete. I would like to be able to use the bathroom again without worry about seeing it show back up in the basement.

Thankfully the only things I've lost so far is a few unimportant things and the carpet that covered most of the floor. But, I'd still like to stress that I can't do things as simple as shower or use the toilet without it possibly backing up and doing more damage to the surrounding structure.

The reason I'm doing a gofundme for this is because frankly I don't have the money to pay for the repairs right now, saving up would mean waiting longer and longer, and let's be real not being able to shower or flush the toilet for a long period is NOT a livable situation, let alone being unable to wash the dishes or do the laundry.

The goal is above the low-ball estimation the plumber gave me due to the fact that my house is honestly pretty old, and while the guy was simply trying to run a snake through the pipes he was giving me a LOT of "well I'm just plain stumped" reactions. I'm not confident that it's going to be a simple fix, and would like to be able to have some financial wiggle room to be able to afford possible complications that could arise while trying to get things fixed proper

Even if you are unable to lend some monetary help, just sharing this campaign with others (like on x/bluesky/tumblr/etc.) would be a huge help. I would like to not have to live in this situation long-term if it can be helped!
