Below are answers to common questions about the Fortitude V whole-house pre-filter systems, including filter types, replacement timing, installation requirements, maintenance, and system performance.
Product Overview
What is the Fortitude V system?
The Fortitude V is a whole-house pre-filter system designed to reduce sediment, chlorine, and other contaminants before water enters your plumbing system.
It helps protect appliances, plumbing fixtures, and downstream filtration systems.
What contaminants does the Fortitude V help reduce?
Fortitude V systems are designed to reduce sediment, soil, silt, sand, rust, chlorine, and certain other common water contaminants depending on the cartridge used.
Filter Types & Flow Rates
What are the flow rates for Fortitude V filters?
Different Fortitude V systems use different filter cartridges depending on application and size.
- Triple Purpose SCZ 10-inch: 6 GPM
- Triple Purpose SCZ 20-inch: 8 GPM
- Sediment Pleated 10-inch: 10 GPM
- Sediment Pleated 20-inch: 20 GPM
Selecting the appropriate size depends on household demand and plumbing configuration.
Can pleated filters be cleaned?
Yes. Pleated sediment filters can be washed and reused up to three times within the recommended replacement period.
Even when cleaned, filters should still be replaced according to schedule to ensure proper performance.
Replacement & Performance
How often should filters be replaced?
Typical replacement timing is:
- 6–12 months for city water
- 4–6 months for well water
In well water applications using SCZ filters, replacement may be required every 3–4 months depending on sediment levels.
Regular replacement helps maintain proper flow rate and filtration efficiency.
Why might water pressure drop after installation?
Water pressure reduction is typically caused by sediment buildup inside the cartridge. Replacing the filter usually restores normal flow.
If water pressure improves after temporarily testing the system without the filter cartridge installed, the cartridge is likely clogged and should be replaced.
How do I release pressure before replacing the filter?
Before replacing the filter, turn off the main water supply. Open the nearest faucet to release built-up water pressure, then press the red pressure relief button on top of the housing cap before removing the filter housing.
Keep a clean cloth or microfiber towel nearby to wipe up any water that may spill during filter replacement.
Should I clean the filter housing during replacement?
Yes. When replacing the filter, clean the inside of the housing and cap with warm water.
Do not use chemicals to wash the housing.
What should I check before reinstalling the filter housing?
Make sure the filter is centered on the stand pipe inside the housing. Check that the O-ring is seated correctly and inspect it for cracks or damage.
Replace the O-ring if it is damaged. Do not overtighten the housing when reinstalling it.
When should the housing be replaced?
To help prevent possible water damage, the filter housing should be replaced every 4 years.
Installation & Setup
What water pressure does the Fortitude V require?
Incoming water pressure should be between 20–75 PSI. The system should not be installed if feed water conditions fall outside the required operating parameters.
What water temperature range does the Fortitude V require?
Incoming water temperature should be between 40°F and 100°F.
The system should also be protected from freezing, direct sunlight, and extreme heat.
Can the Fortitude V be installed outdoors?
The Fortitude V should not be installed in an area exposed to direct sunlight, freezing temperatures, or extreme heat.
If installed in a garage, utility area, or other exposed space, make sure the system is properly protected from environmental conditions.
How much clearance does the Fortitude V need?
The system should be mounted with at least 6 inches of ground clearance from the floor to the base of the system.
The mounting bracket should be level and secured to a stud to help distribute stress evenly.
Should I install a bypass with the Fortitude V?
A bypass is not required, but it is recommended. A bypass can help reduce downtime during repairs, maintenance, or system replacement.
How many wraps of Teflon tape should I use?
Use 5 to 6 wraps of Teflon tape on the 1-inch male threaded fittings before connecting the plumbing to the system.
What should I do if the system leaks after installation?
Immediately shut off the main water supply valve if there are leaks.
Check the leaking area for a loose connection or whether more Teflon tape is needed on the threaded fitting.
What should I do after installing or replacing a filter?
After installing or replacing a filter:
- Turn the main water supply back on.
- Check for leaks.
- Run the nearest faucet for 10 minutes to release trapped air bubbles or carbon fines if a carbon filter is installed.
Document the installation or replacement date so the filter can be replaced on schedule.
General Questions
Do I need to inspect the system before installation?
Yes. Before installation, remove the system and components from the box and inspect all connection fittings carefully.
If any part is cracked, broken, or damaged during shipping, do not proceed with installation. Contact Aquasure or your distributor for assistance.
Can the Fortitude V be used with untreated or unsafe water?
Do not use the system with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.
What should I do if my main shut-off valve does not fully stop the water?
Do not proceed with installation if the main water supply valve does not completely shut off the water.
Contact a licensed plumber to fix the shut-off valve before installing the system.
Does metal plumbing require any special consideration?
If the system is installed with conductive metal plumbing, such as copper or galvanized pipe, the plastic components may interrupt plumbing continuity.
A grounded jumper wire may be required to reestablish continuity. Contact a licensed plumber if you are unsure whether this applies to your home.
