Fafco Internal Collector Fouling

Visible algae or dirt buildup inside clear Fafco panel tubes, reducing performance.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Poor pool water chemistry, Long periods of stagnation in panels, No periodic high-flow flushing, Organic debris entering solar loop

Safety: Handle pool chemicals carefully and follow all safety instructions.

Balance water: Test and correct pool chemistry, especially sanitizer and pH, to prevent algae growth.
Flush panels: Periodically run the Fafco system at full flow to help scour internal surfaces.
Install strainer: Ensure a fine strainer or filter is present before the solar feed to prevent debris entry.
Severe fouling: If performance remains poor, panels may need professional cleaning or replacement.
