How often should you flush your water heater?

Grumpty's answer
Every 12 months
Why bother
Sediment shortens its life and saps efficiency. This is an essentials-tier job. Skip it and you're inviting the expensive kind of problem, or the dangerous kind.
When to start thinking about it
Give yourself about 7 days' notice. That's when Grumpty starts grumbling, so it doesn't land on you the day it's due. Mark it done and Grumpty sets the next one, every 12 months, so you can go back to forgetting it exists.
Let Grumpty remember it for you
Add it once. Grumpty tracks the date, grumbles when it's due, and rolls it forward the moment you mark it done. No spreadsheets, no sticky notes, no forgetting.
