Toilet/Bathtub Slow Drain
One of my bathrooms is having an issue with the toilet and bathtub draining super slow. Toilet gets clogged the majority of the time any adult goes “#2” and the bathtub starts to fill up during showers and just drains slow during any use. I’ve snaked everything I can and there are no noticeable obstructions all the way to where the bathroom pipes connect with the main sewer. I opened the drum trap for the tub and no blockage there or down pipe. Nothing else in the house has any issues. The only thing I can figure is that there is some kind of venting issue, but all the tub pipes are buried in the wall, and I don’t want to tear into it until I’m sure it is worth the effort. This is the 1st floor bathroom that’s having the issue and 2nd floor right above it is fine. Thoughts?
