I called City Master Plumbing on Labor Day. Our bathroom sink was 'dispensing' water and waste all over the floor which in turn was flooding into other rooms. Mike asked questions, explained how the septic and sewer systems were set up, and what he thought the issue was. He said to try his suggestions and if the problem wasn't fixed he would come out and take a look. He was 100% correct, saving me from having to pay emergency and holiday prices that most plumbers charge.
