That $400 backflow preventer I installed backwards cost me double
Last spring I did a rush job on a restaurant remodel downtown and slapped in a new backflow preventer without reading the flow arrow on the body. Thought I knew better since I had done a dozen residential ones. Three days later the health inspector flagged it during a walk through and the plumber who fixed it charged me $250 for labor and I had to buy another unit for $150. The kicker was the original one was fine I just had it flipped around and could have saved the whole thing with a second look. Has anyone else made a silly mistake like this on a commercial job that cost way more than it should have?

Dang, that flow arrow gets me every time too." I did something similar on a school boiler room last winter. I reversed the pressure relief valve because the threads looked the same both ways. Next day the janitor called saying water was spraying everywhere. Had to pay a steamfitter $600 on a Saturday to come fix it and I still owe him a favor. The original valve was fine too, just backwards.

Always check for that little arrow before you wrench anything tight, saves a headache every time.
