Below are answers to common questions about the Fortitude Pro whole-house filtration system, including sizing, media type, backwashing, and system performance.
Product Overview
What is the Fortitude Pro tank?
The Fortitude Pro is a whole-house filtration system designed to remove chlorine, odors, heavy metals, and other contaminants from your water supply using activated carbon and KDF media.
How do you tell the difference between a Fortitude Pro (FP) tank and a Water Softener (WS) tank?
The difference is the media inside the tank. Fortitude Pro tanks contain black carbon/KDF media, while water softener tanks contain amber-colored resin beads.
What type of media is inside the Fortitude Pro tank?
The Fortitude Pro uses a combination of activated carbon (GAC) and KDF media to reduce chlorine, odors, heavy metals, and certain other contaminants.
What color is the Fortitude Pro media?
The filtration media inside the Fortitude Pro tank is black.
Media & Performance
How long does the Fortitude Pro media last?
With proper maintenance and routine backwashing, the media typically lasts 3–5 years. Lifespan depends on chlorine levels, water quality, and maintenance frequency.
How much chlorine can the system remove?
The Fortitude Pro can remove up to approximately 4 PPM of chlorine under normal operating conditions.
What is the difference between KDF-55 and KDF-85?
KDF-55 is typically used for municipal (city) water and is effective at removing chlorine and heavy metals.
KDF-85 is better suited for well water systems and is effective at reducing iron and hydrogen sulfide (sulfur odor).
Neither KDF-55 nor KDF-85 is designed to remove sulfates. Sulfates require treatment methods such as reverse osmosis or anion exchange.
Sizing & Compatibility
What sizes are available for the Fortitude Pro?
The Fortitude Pro is available in multiple capacities, including:
- 600,000 gallons
- 800,000 gallons

System size selection depends on household water usage and system pairing.
Which Fortitude Pro pairs with a 48k water softener?
The 1,000,000-gallon Fortitude Pro system is typically paired with a 48k water softener.
Backwash & Operation
How often should the Fortitude Pro be backwashed?
The system should be manually backwashed every 7–10 days to maintain media performance and prevent buildup.
How long is the backwash cycle?
The backwash stage runs for 15 minutes, followed by a 10-minute fast rinse. The total cleaning time is approximately 25 minutes.
How many functions does the manual valve have?
The manual valve has three positions: Filter, Backwash, and Fast Rinse. These settings allow you to control normal operation and cleaning cycles.
Upgrades & Valve Questions
Can the manual valve be upgraded?
Yes. Customers who prefer automatic operation can purchase an electronic control head upgrade compatible with the Fortitude Pro system.
