The popups have never worked properly on our bathroom sinks, so I decided to fix them. I hadn't looked at these traps before, and this just doesn't look right to me. That said, we haven't had any problems with the water failing to drain or with any odors. Do I need to change this? If so, how do I do that? While I can move the trap a bit lower, I can't get it low enough to go directly into the waste line. Also, while I'm here, does anyone have any thoughts about the spring loaded popups vs. the lever arm ones?
