How to fix low water flow in Jandy Water Filtration System?
- H
  Helen WardAug 9, 2025
  Low water flow in your Jandy Water Filtration System can stem from several causes. Start by checking and cleaning the filter system strainer baskets, as they may be dirty. Inspect all connections between the pool intake and pump for air leaks on the suction side. Look for any restrictions or blockages in the suction or return lines, such as debris or partially closed valves. The filter cartridge might need attention, so clean or replace it as instructed. Ensure the pool water level is high enough, above the pump inlet line. Prime the pump by filling it with water at the basket and replacing the lid. If the pump impeller vanes are blocked or the pump is operating under speed due to low voltage, a technician or electrician is required.

Why is the water not clear in my Jandy Water Filtration System?

  If the water in your pool isn't clear, it could be due to several reasons. You might not have enough disinfectant; in that case, check and adjust the disinfectant level. The pool chemistry could be off, so test and adjust it accordingly. Heavy use or dirt can also affect water clarity; adjust the filter time or water chemistry to compensate. Ensure the pump runs long enough by increasing its run time. A dirty filter can also cause this issue; clean it following the instructions. Finally, check for holes in the filter element and replace the filter cartridge if needed.

  Short filter cycles in your Jandy Water Filtration System can be caused by a few things. Algae clogging the filter is one possibility, so check the disinfectant content. Incorrect water chemistry can also be a factor; check the pH, total alkalinity, and TDS. Make sure strainer baskets are being used and are not broken; replace them if necessary. The pump output might exceed the filter's design flow rate, so check the pump performance. Lastly, ineffective cleaning can cause this, so clean or replace the filter cartridge as instructed.
