INSTALLATION & USE
Mounting and Cartridge Loading
- Mount the cap bracket securely to wall studs or a solid surface, ensuring the 1" NPT ports align with your supply and outlet lines.
- Lubricate the o-ring with clean silicone grease, insert your chosen 10" filter cartridge into the blue sump, and thread the sump onto the cap hand-tight.
- Slowly open the inlet valve and check all connections for leaks, then use the pressure release button before unscrewing the sump for future cartridge changes.
- Replace the filter cartridge according to the manufacturer's schedule and inspect the housing annually for cracks or wear, replacing the entire unit as needed.
COMPATIBILITY
Cartridge and System Fit
This Big Blue housing accepts all standard 10-inch cartridges with 2.5-inch outer diameter, including sediment filters, carbon blocks, pleated polyester, and specialty media from brands like Pentek, Hydronix, Culligan, and Matrikx. The 1" NPT threading integrates directly into whole house plumbing with standard pipe fittings, and the high-flow design supports flow rates up to 25 GPM depending on cartridge selection and system pressure.
🔧 Always depressurize the housing with the pressure release button before unscrewing the sump. Trying to remove a pressurized housing can spray water across your utility room and make o-ring removal nearly impossible.
