Scale Doesn't Stand A Chance
Here's the ugly truth nobody tells you when you buy a water heater: scale build-up from hard water is the #1 reason these things die early. Calcium and lime just move in and never leave — clogging your heat exchanger, choking your flow rate, and quietly draining your wallet through your utility bill.
The Fortress doesn't fight hard water with salt tanks or harsh chemicals. It out-smarts it. Inside every Fortress unit, our scale-prevention media converts dissolved hardness minerals — the stuff that turns into rock-hard calcite scale — into microscopic, powerless particles (aragonite and vaterite, if you want to get nerdy about it). Same chemical makeup as regular scale. Completely different personality.
-
These particles just wash right through your system instead of bonding to it.
-
No salt bags to haul. No brine tank to babysit. No electricity to run. Just water going in one side and protected water coming out the other.
-
The result: longer-lasting pipes, a happier water heater, and up to 30% more efficiency where scale used to be sabotaging your system.
SoftPro Fortress Home
The Compact Defender
Not every house needs a beast. Some just need a bodyguard that does its job and gets out of the way.
Fortress Home is built for point-of-use protection — sized right for standard residential plumbing, no wasted space, no overkill. It sits quietly under your sink or at your water heater line and just... handles it. Scale doesn't stand a chance. Neither does the guesswork of "is this thing too small for my house?" (It's not.)
- Service flow rate up to 6 GPM
- Compact 7" x 13-1/2" footprint — fits where bigger units can't
- Media replacement every 2 years
- 3/4" FNPT connections for a straightforward install
Best for: Standard single-family homes wanting reliable, no-fuss scale protection.
SoftPro Fortress Pro
The One Serious Homeowners Reach For
You didn't buy a nice water heater to let hard water eat it alive. Fortress Pro is the step-up — more flow, longer-lasting media, and the muscle to handle whole-home demand or light commercial use without blinking.
This is the unit for the house with five bathrooms, the family that runs three showers before 7am, or the light commercial space that can't afford downtime. Bigger tank. Bigger flow. Way bigger peace of mind.
- Service flow rate up to 10 GPM
- Media lasts up to 5 years — install it and forget about it
- Fiberglass tank with a flexible, zippered neoprene cover
- 1" FNPT connections with easy-clip install
Best for: Whole-house protection, larger households, and light commercial applications.
SoftPro Fortress Commercial
The Heavyweight
This isn't a "maybe someday" unit. This is for buildings that move serious volume, every single day — and can't afford scale build-up slowing anything down.
Floor-standing. Built tough. Sized for restaurants, apartment complexes, offices, anywhere hard water shows up in force and needs to be told "not today." When Home and Pro aren't enough buildings, Commercial is enough Fortress.
- Service flow rate up to 16 GPM continuous
- Floor-standing 10" x 54" fiberglass tank with zippered neoprene cover
- Built-in bypass valve for effortless servicing
- Media lasts up to 5 years, with gravel bed for even distribution.
Best for: High-volume commercial buildings and properties with heavy water demand.

See What Scale Actually Does (So You Never Have To)
Two pipes. Same hard water. One protected by Fortress, one not. Guess which one looks like a science experiment gone wrong.
Untreated pipes cake up with hard, crystalline calcite. Heat exchangers clog. Flow drops. Fortress-treated water? Clean lines, full flow, no drama.
This is the difference between replacing your water heater in 6 years… or 15.
Goes In Fast. Works Forever.
Every Fortress model is built for straightforward professional installation — no rewiring, no drainage lines, no electrical hookup required. Just tie it into your water line at the recommended point of use or point of entry, mount it with the included hardware, and you're protected.
We recommend professional installation to make sure your Fortress is sized and positioned correctly for your home or building's plumbing — get it right once, and it just works, quietly, for years.
We Stand Behind This. Here's Exactly How.
Your SoftPro Fortress is covered by a 1-year limited warranty from the date of installation, covering defects in material and workmanship — as long as it's installed correctly per the manual.
What voids it: improper installation, abuse or misuse, incoming water that doesn't meet EPA drinking water standards, chlorine levels above 2.0 ppm without pretreatment, or purchasing through unauthorized internet/e-commerce resale channels.
Media cartridge coverage: Defective parts are replaced or repaired at our discretion. Media replacement is expected within 2 years and is limited to genuine SoftPro-approved media — this warranty doesn't cover media damage from chlorine, oxidizing agents, or water conditions outside the specified limits.
What's not covered: Labor costs, incidental or consequential damages (freight, lost profits, property damage from product failure), or damage caused by neglect, vandalism, or conditions outside our control.
To file a claim, you'll need your model number, serial number, and installation date on hand. Call our support line or start a chat and we'll walk you through it.
Frequently Asked Questions
Got questions? We’ve got answers!
Do I need a Home, Pro, or Commercial Fortress?
Match it to your flow needs and building size. Home covers standard point-of-use protection up to 6 GPM. Pro steps up to 10 GPM for whole-home or light commercial use. Commercial handles up to 16 GPM continuous for high-volume buildings.
Does it use salt or chemicals?
Zero. Fortress is 100% salt-free and chemical-free — it's a physical media conversion process, not a softener.
How long does the media last?
Home: 2 years. Pro & Commercial: 5 years, under normal operating conditions.
Will this fix water that's already hard?
Fortress prevents new scales from forming and bonding — it doesn't remove existing built-up scale from old pipes or appliances.
Does it need electricity?
Nope. Fully passive system — no power, no moving parts to fail.
