Alkoholik

I live in an older home, and while I’ve dealt with small clogs before, this time feels different. Multiple drains in the house are starting to slow down at the same time. It’s not just one sink or one bathroom anymore. I’m starting to wonder if this could be related to the main sewer line rather than individual pipes. How serious is this usually considered?

I had something very similar happen in my own house, and at first it seemed random and harmless. When the washing machine would drain, the nearby sink would bubble and gurgle a bit, which definitely didn’t feel normal. My first step was checking the sink trap and cleaning it, but that didn’t fix anything. After that I looked deeper into the shared drain line, because multiple fixtures were clearly connected https://bens.plumbing/areas/kirkland/sewer-line-repair/ and that’s where I suspected a partial blockage or poor venting. In my case it turned out to be a buildup further down the pipe slowing airflow and water movement. A drain snake and proper flushing helped a lot. If you see bubbling, start with checking shared pipes and ventilation first.
