If you are experiencing reduced water pressure after installing your Fortitude V system, the issue is often related to filter restriction.
Overview
This article covers common Fortitude V troubleshooting concerns including:
- Leaks at the system connection or housing area
- Black carbon particles appearing in the home’s water
- Low water pressure caused by a clogged filter cartridge
If the issue continues after completing the steps below, contact Aquasure Customer Support for further assistance.
Follow the steps below to determine whether the filter is causing the issue.
Leak at System Connection or Housing
If you notice a leak during installation, startup, or filter replacement, immediately shut off the main water supply before inspecting the system.
Check the leaking area for a loose connection. If the leak is coming from a threaded connection, remove and reinstall the fitting using Teflon tape only. Aquasure recommends applying 5 to 6 wraps of Teflon tape to the 1" male threaded fitting before reconnecting.
If the leak appears near the filter housing:
- Shut off the main water supply
- Open the nearest faucet to release built-up pressure
- Press the red pressure relief button on top of the housing cap
- Remove the housing using the supplied housing wrench
- Check that the O-ring is seated correctly inside the housing
- Inspect the O-ring for cracks or damage
- Replace the O-ring if it is damaged
- Reinstall the housing without overtightening
After reinstalling the connection or housing, slowly turn the main water supply back on and check for leaks.
Black Carbon in Home
If you notice black carbon particles in your home’s water after installation, startup, or filter replacement, the system may need to be flushed.
Turn on the nearest faucet and let the water run for 10 minutes to help release trapped air bubbles or carbon fines from the system.
After flushing:
- Check whether the water runs clear
Avoid additional troubleshooting unless instructed by Aquasure Customer Support.
Low Water Pressure
If you are experiencing reduced water pressure after installing or using your Fortitude V system, the filter cartridge may be restricted by contaminant buildup.
Follow the steps below to determine whether the filter cartridge is causing the issue.
- Turn off the main water supply.
- Open the nearest faucet to release built-up pressure, then press the red pressure relief button on top of the housing cap.
- Use the supplied housing wrench to remove the filter housing, then carefully take out the filter cartridge.
- Restore water flow temporarily without the filter installed and allow the system to run for up to 24 hours to observe any changes in pressure.
-
Monitor the water pressure:
- If water pressure improves, the cartridge is likely clogged and should be replaced.
- If water pressure does not improve, the issue may not be related to the cartridge.
- Take a photo of the removed filter if sediment buildup is visible. This can help document the issue if further support is needed.
- Before returning the system to normal use, reinstall the existing cartridge or replace it with a new one if clogging is confirmed.
- Check that the O-ring is seated correctly inside the housing and inspect it for cracks or damage. Replace the O-ring if it is damaged.
- Reinstall the housing, without overtightening, then turn the main water supply back on and check for leaks.
- Run the nearest faucet for 10 minutes to release trapped air from the system.
If pressure improves without the filter installed, the cartridge is likely clogged and should be replaced. If pressure remains low without the filter, another issue may be affecting water flow.
Note: Regular filter replacement helps prevent pressure-related issues and ensures consistent system performance.
When to Contact Support
Contact Aquasure Customer Support if:
