Had a contractor convince me to try a new sink drain layout...
I was talking to this plumber named Greg last Tuesday while he was fixing a leak in my basement. He mentioned he sees people install P-traps backwards all the time because the packaging shows a misleading diagram. That got me thinking about all the shower heads I've bought that had arrows pointing the wrong way for water flow. He showed me a photo from a job where someone used a flex hose that kinked so bad it reduced pressure to a trickle, like 0.2 gallons per minute instead of 2.5. It hit me that even simple things like faucet handles get designed with zero logic sometimes, like a cold hand shower that burns you if you turn it the wrong direction. Has anyone else had a pro point out a design flaw you never noticed before because you just trusted the instructions?

Wait, I think you might have that backwards... P-traps actually have a pretty clear direction if you look at how the curved part sits. The inlet should always be higher than the outlet, and most diagrams show that right. Greg might've been talking about something else though.
