Why is my Port A Cool Freezer overflowing or spitting water?
- DDaniel Good Jr.Sep 2, 2025
If your Port-A-Cool Freezer unit overflows from the sump tank or is spitting water through the fan, the float valve hose might be loose at the bulkhead fitting or at the float valve; tighten the connections and/or replace the hose washers. Alternatively, the water pressure might be too high, preventing the float valve from shutting off (50 psi max.); reduce the water pressure by checking the in-line reducer. It's also possible that the float valve isn't seating properly; check for particles in the valve and replace the float valve if needed. Finally, adjust the spray bar valve to reduce excess water flow.
