Arrived to home for drip on cap for previous drain cleaning we did. Upon inspection found that 3 dollar plugs in total are leaking and popped off. So anytime any fixture in the home is used it is just flooding the basement. Home has house trap and could be the main problem. Not sure if there is a problem further down line passed house trap or not. Plumbing and drainage is old and could be compromised. Basement is full of sewage so due to hazards we can not further diagnose at this time. Let customer know that we work with a restoration company that will clean this up that way we can asses issues. Customer is going to have this cleaned up asap and our drain specialist will be here when ready to give options to fix problems.
