Frequently Asked Questions

Q: How do the DuPlex™ Water Filter Systems differ from an ordinary water system?

• A: Ordinary water filters generally use one cartridge to filter contaminants or particles from the water. DuPlex™ systems use multiple cartridges in series to filter different types of contaminants at the same time, allowing users to select cartridge types to match the application requirement.

Q: Will DuPlex™ systems remove hardness, sodium, and salts from the water?

• A: No. Unlike reverse osmosis systems, inline filter systems do not filter out contaminants in solution. They are designed to filter particulate, color, oxidized iron, algae, cysts, taste, and odor. Some specialized cartridges are available to soften water but generally have low capacity and are best used in conjunction with a regenerating water softener.

Q: Does cartridge filtration remove bacteria, Cryptosporidium, or viruses?

• A: Where known microbiological contamination exists, specialized pre-treatment is recommended to ensure a safe water supply to the water filter system. An added UV system can act as an effective secondary barrier when properly installed and maintained.

Q: Where is the system installed?

• A: Typically, the system is installed where the water enters the building, often in the basement or crawlspace for easier maintenance access. It must be installed in a heated area not subject to freezing temperatures.

Q: How much water does DuPlex™ systems produce?

• A: FS-YT series filter systems with 20” housings produce approximately 12 USGPM (45 liters/min) with new sediment and carbon block cartridges. Full-flow (Big Blue) FS-BB series systems with 10” or 20” housings can produce about 20 USGPM (76 liters/min).

Q: What is the standard warranty with DuPlex™ systems?

• A: Every water filter system comes with a standard one-year limited warranty on all parts and repair labor. Normal filter cartridge replacement is excluded from the warranty.

Q: What is the maintenance schedule for the system?

• A: Replace all filter cartridges every three months, or more often depending on local water conditions and total water usage. Severe water conditions may shorten cartridge life significantly.

Q: When should the cartridges be changed?

• A: Cartridges should be changed if you notice gradually decreasing water pressure, taste, or odor. If the differential pressure between cartridges reaches 10 PSI, they should be changed.
