I was trying to figure out what was going on with the pipes leaving my basement (separate apartment) and my house. We had a washing machine clog, twice in five months, and I needed some answers.
I called a free sewer specialist from this site that came highly recommended. They snaked the pipes with a camera and said that the pipe leading from my outside cleanout to the city was the problem. Then gave me a $7K quote to put in new ones.
I called Peter for a 2nd opinion. He was skeptical about the diagnosis. He sent me Tenzin and his assistant. They categorically proved through snaking with a camera and testing with water and flushing toilets how faulty and wrong the advice was from the first company. The pipes were fine. It was something that got into the 1 1/2 inch pipe leading from the washing machine.
If not for Tenzin and Peter's expertise, them doing the work, and me being willing to pay some money for real advice, I would be out $7-8K. Don't go with the free guys. I'm really grateful to this company.
