Hey, new here. I'm pretty much clueless about plumbing but I need help. I've been renting a basement unit for 3 years and have needed my kitchen and laundry sink line professionally snaked 3 times in the past year and a half due to it clogging solid. I've been using hair traps, mesh screens, and panyhose to catch lint, but it's clogged solid once again today. My landlords insist that it's something I'm doing, so this is creating a lot of tension with the rental situation. I want to know if there's something I can do myself to take care of it and prevent it from happening again. Thanks. Little bit more info: I've tried boiling water and plunging. It's a 1960's house. I think the plumbing is a bit of a mess. No floor drain. Pretty sure it was snaked through a vent on the roof.
