re: Admit Your Dumbest Homeowner Repair Mistakes

Garbage disposal went out. Replaced it with a new one. Didn't do dishes for a couple of days due eating out and also replacing piping with PEX in same general time frame. Starting doing dishes and dish washer would not drain water after completing a cycle. Fiddled with it a couple of days. Finally went to buy a new dish washer, connected it, same problem with not draining. Realized i forgot to remove the plug on the garbage disposal when connecting the dish washer drain line.

Many more to list but as they say, they are life lessons you won't forget.
