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.
You could have a plumber come out and clean the line and locate the issue for probably a reasonable price. Once the issue is located, you could dig the pipe out yourself and then have a plumber repair or replace it to save money.
I watch a YouTube channel called Drain Addict and this dude uses a pressure washer with special heads on it to clean out drains and cut away roots. He then uses an inspection camera with a locating beacon to identify where the line is buried, where the break is at, and how deep.
