Frustrated with plumbers!
My sister is at her wits end. She's owned her house for 12 years now. First 10 no plumbing problems. Two years ago she had a sewer backup. Plumber comes in and says the backup was due to baby wipes and feminine hygiene products and he pulled a ton out of her system. She is post menopause and does not use these products! I was there when the plumber originally came out and told him that she does not use those products (she was working at the time so I was there). He said that was impossible because it was coming from her system. Few months later it happens again. Same thing with the plumber saying it's impossible that it's not coming from her toilet system. Then it happened again over the summer and she got another plumber who power jetted her system. Happened again yesterday. None of the products pulled out were things she uses and she only throws toilet paper down the toilet. Plumbers keep saying it's impossible that this stuff is not coming from her system but clearly it's not coming from her system and she is not throwing this crap down her toilet. This second plumber is coming out to put a camera down her system but that's been done before, repairs made and still it's happening. Any thoughts?
The first repair was to replace the main drain pipe in her driveway that had shifted and second was the power wash. Of course she knows this is likely to cost her a fortune but she just wants to get to the root of the problem. Could this be a problem with the city sewer line?
