Essentially any large flush through my house (washer, shower) has started coming up through my basement drain in the floor. I bought this house two years ago for full price and already am 20k deep in hidden repairs (all from basement flooding, yayy). I can explain if I need to, but I really just don’t have extra funds to put to this after the others. I’m thinking I can’t bathe with more than a gallon of water and not wash dishes or clothing until I can fix it.
Edit: Thank you for all the comments. I’ll hire a plumber.
Most sump pumps, at least in my area, drain directly to the outside, there’s basically a pipe that goes from my sump up and out of my basement and opens out into my yard.
I wouldn’t really want to count on a sump pump for this kind of issue though. At best you’re basically just putting a bandaid on a sucking chest wound. You could also run into some legal issues for knowingly using it to discharge sewage into your yard (and why would you even want to do that in the first place?)
It would also be pretty rough on the pump, they’re usually not meant to handle solids like the hair clogs, bits of food, fecal matter, etc.
Assuming you’d have an actual sump pit installed, there’s often some water left standing in the pit, you probably don’t want that to be sewage water.
