In my case it’s because the last several owners of this house were idiots that cheaped out on everything and thought they knew better than the professionals do… my plumbing is a wonderful variety of crap soldered to different crap that I think was partially salvaged from the Titanic or something.
And since I’m renting, I have no ambition to rip anything out and fix it properly unless it breaks.
Why does that happen? Is the pipe to the bathroom wider than the kitchen sink?
