A water heater flush takes under an hour, once a year. Skip it for too long and you cut the life of a $1,500 appliance in half. Set a yearly email reminder, mark it done when you flush, and the next one is already scheduled.
Done in seconds. No sign-up required.
Skipping is silent. The damage is not.

Nothing triggers it. The water heater lives in a basement or a closet and gives no feedback until it fails. No dashboard light, no app notification, no annual bill that asks if you want to flush it. The task does not appear in your week until something goes wrong.
Most homeowners know they are supposed to flush it. They just have no system that surfaces the task on the right week, every year. The window passes, life moves on, and by year three or four the sediment has hardened into a layer the drain valve cannot push out.
A yearly email reminder closes the gap. You set the date once. The reminder arrives the same week every year. If you do not mark it done, it follows up. The system handles the remembering so the appliance handles the heating.
A water heater flush reminder is the simplest kind: a fixed date, recurring yearly, with a one-click "done" link. Most people set it for the same week they had the tank installed or last serviced, then never think about it again.
One year from your last flush, or any date a year out if this is your first. Same week each year keeps it predictable.
A short reminder lands in your inbox on the day, with a checklist link and the option to snooze if you are traveling.
One click to confirm the flush is complete. If you do not click, BoldRemind sends a follow-up so the task does not quietly slip again.
It builds in layers. Then it hardens. Then it kills the tank.
In a gas heater, sediment forms a barrier between the burner and the water. The burner runs longer to heat through it, energy bills climb, and the tank bottom overheats and weakens.
Full consequence breakdown →When water trapped under sediment turns to steam, the bubbles escape with a popping sound. By the time you hear it from the kitchen, the layer is thick enough to need a real flush.
Signs to watch for →A yearly flush costs nothing if you DIY, or about $100 to $200 if a plumber does it. A tank that dies from sediment costs you the appliance, the install labor, and often a flooded floor.
Cost comparison →The details, by question.
Once a year for most homes. Twice a year if you have hard water, well water, or a tankless unit. The yearly cadence is the safe default that manufacturers and plumbers recommend across both gas and electric tank heaters.
BoldRemind sends a free email reminder on the date you pick, then follows up if you do not mark it done. You set it once for one year from your last flush, and it runs the same date every year. No app, no account, no missed cycles.
Yes. The U.S. Department of Energy notes that sediment buildup reduces heating efficiency and shortens tank life. A flush takes 30 to 60 minutes and protects an appliance that costs $1,200 to $3,000 to replace.
Flush it now. If the tank is more than five years old and has never been flushed, schedule the first flush during business hours in case the drain valve clogs or fails — that is the most common DIY issue with neglected tanks.
Yes. When you set the reminder, you can mark it as recurring yearly. The email arrives on the same date each year, with a link to mark it done or snooze it. You do not have to remember to renew or reset anything.
Most homeowners can flush a tank-style water heater themselves with a garden hose in under an hour. Tankless units are slightly more involved and may benefit from a plumber the first time. See the step-by-step DIY guide linked below.
Free. No account. Takes 30 seconds. You'll get an email the same week every year — and follow-ups if you don't mark it done.
