The Fortitude V Series is designed for wall-mounted, point-of-entry filtration to treat water throughout the home. Installation involves connecting directly to the main water line, and professional installation is recommended for those without plumbing experience.
Improper installation may result in leaks, system damage, or voided warranty coverage. For full step-by-step instructions, refer to the official owner’s manual included with your system.
Pre-Installation Prep: Required Conditions
Before installation, ensure the following conditions are met to support proper system performance and safety:
- Water pressure must be between 20–75 PSI
- Water temperature must remain between 40°F–100°F
- Water supply must be microbiologically safe or properly disinfected
- Installation area must be protected from direct sunlight, freezing, and extreme heat
- Main shut-off valve must be fully operational and able to stop all water flow
These requirements are critical. Failure to meet them may result in system damage or voided warranty.
Basic Installation Overview
Installation follows a single-stage filtration setup. Multi-stage systems follow the same instructions.
- Shut off the main water supply.
- Mount the system securely to the wall using the provided bracket.
- Connect inlet and outlet plumbing using appropriate fittings and Teflon tape.
- Insert the filter cartridge into the housing.
- For multi-stage housing, make sure each filter is inserted in the correct order.
- Tighten housing and confirm the O-ring is properly seated.
- Slowly restore water supply and check for leaks.
- Flush the system by running water for approximately 10 minutes.
The system must be installed with proper alignment, secure fittings, and correct flow direction to operate as intended. For additional setup guidance, watch Aquasure’s Fortitude V Series installation guide.
Mounting and Clearance Requirements
Proper mounting is essential for both performance and ongoing maintenance.
- The system must be securely mounted to a wall stud using the provided bracket
- The bracket should be leveled to prevent uneven stress on the housing
- A minimum of 25 inches of clearance below the system is required to allow for filter housing removal and replacement
While the manual references a smaller clearance, additional space is required to ensure safe and accessible filter maintenance over time.
Professional Installation Recommendation
Professional installation is recommended if:
- There is limited experience with cutting or modifying plumbing lines
- The home uses metal plumbing (copper or galvanized) requiring grounding considerations
- A bypass loop needs to be installed
- Local plumbing codes require licensed installation
- There is uncertainty around mounting, spacing, or connection setup
A licensed plumber can ensure code compliance, proper grounding continuity, and long-term reliability.
After Installation
After installation is complete:
- Slowly turn the main water supply back on
- Check all connections for leaks or loose fittings
- Run water at the nearest faucet for at least 10 minutes to flush air and carbon fines
- Monitor the system during initial use to confirm stable operation
If leaks are detected, shut off the water immediately and correct the issue before continuing.
