Plumber of the Year is one of the hidden badges in 7 Days Cat-Sitting, and it has nothing to do with surviving the week or reaching an ending. It unlocks purely through a repeated interaction with the bathroom toilet, which means you can earn it in a single session once you set the run up correctly.
Quick answer: Flush the house toilet 250 times in one run. The “PLUMBER OF THE YEAR!” badge pops the moment the 250th flush registers.
Set up a run with unlimited time first
Flushing the toilet 250 times takes roughly 21 minutes of real time, so you cannot let the night end or fail while you grind it out. Start a fresh game, then clear the normal tasks and any anomaly that appears so the run keeps going without a game over. That stable state is what gives you the open-ended time you need.
Handle the standard chores the game expects before you head to the bathroom. Take the cat food from the kitchen cupboard and fill Whiskers’ bowl, prepare the TV dinner in the microwave, and turn on the TV. Keep an eye out for any anomaly and respond to it so nothing forces an early ending.

Do this groundwork before you start flushing. Once the house is stable, nothing should interrupt the long stretch of toilet flushes ahead.

How to confirm the badge unlocked
When the 250th flush lands, the standard Roblox “Badge Awarded” popup appears in the lower-right corner of the screen showing the name PLUMBER OF THE YEAR!. That notification is your confirmation that it worked, and the badge stays attached to your Roblox profile permanently once earned.
There is no other trigger to chase here. The toilet flush is the entire requirement, so once the award pops you are free to leave the bathroom and continue or end the run however you like.
