Your steam generator is the heart of your home spa experience. It works hard behind the scenes to create the perfect environment — but it faces one persistent obstacle: hard water. Over time, minerals like calcium and magnesium settle inside the tank, creating sediment that reduces efficiency and shortens the lifespan of your unit.
At TheSteamStore.com, we recommend the Mr. Steam AutoFlush® — the set-it-and-forget-it solution to protect your investment.
Clean Steam Without Lifting a Finger
AutoFlush is a Mr. Steam exclusive product designed to promote a long, healthy life for your generator. It's an automatic self-cleaning system that takes the guesswork out of maintenance — automating everything in the background so you never have to think about it.
Compatible with: MS90, MS150, MS225, MS400, MSSUPER1, MSSUPER2, and MSSUPER3 generators. Not compatible with the MX Series.
How the AutoFlush System Works
The AutoFlush system works in two directions — flushing out what shouldn't be there and bringing in fresh water for your next session:
- After every session: Two hours after your steam bath ends, the system automatically initiates a flush. This time delay allows the water to cool before draining by gravity for a safe, gentle operation.
- Fresh water every time: AutoFlush automatically introduces fresh water from your home's supply — so every session starts clean, not with water that has been sitting in the tank.
- Electronic valve technology: The system uses a 1/2" electronically-activated valve to flush out sediment and impurities. No clogging, no buttons to push, nothing to remember.
- Express Steam compatibility: If your system has Express Steam installed, AutoFlush drains for ten minutes then automatically refills with fresh water to begin the pre-heat cycle.
Why AutoFlush Is a Must-Have Upgrade
1. Prolongs generator life. By removing old water and mineral buildup after every session, you help prevent the heating elements from being coated in scale — keeping the generator running at peak performance for years.
2. Nothing to remember. The drain is automatically initiated every time. There's no risk of forgetting to maintain the unit, no manual draining process, and no maintenance schedule to keep track of.
3. Healthier steam. Standing water in a generator tank can become stagnant between sessions. AutoFlush ensures that every session starts with fresh water directly from your home's supply.
Hard water areas: If your home has hard water, an auto-flush system isn't optional — it's essential. Mineral scale buildup is one of the most common causes of heating element failure in steam generators, and it's almost entirely preventable with automatic flushing after every use.
Easy Installation
The AutoFlush is a simple plug-and-play add-on. It connects to the bottom of your MS or Super Series generator and plumbs to your drain line. The box includes the AutoFlush valve with cord and installation instructions. Installation should be performed by a licensed plumber.
