What to do if my Pentair Water Filtration System softener fails to use salt?
- S
  Sara CarneyAug 23, 2025
  If your Pentair Water Filtration System softener isn't using salt, start by cleaning the drain line and/or flow control if they are plugged or restricted. Next, inspect the injector; clean or replace it and the screen if plugged. Also, check for any restrictions in the BLFC and ensure the safety float is not stuck if there's no water in the brine tank. The line pressure must be at least 1.4 bar. Check the brine line for air leaks if it injects air during brine draw.

  Brittany ParksAug 26, 2025
  If your Pentair Control Unit softener fails to regenerate automatically, ensure it's connected to a constant power source. Check the meter cable for disconnections or faults, reconnecting or replacing it as needed. If the power cord is defective, replace it. Also, examine the controller, meter, or sensor for defects and replace or repair them. Finally, verify that the unit is programmed correctly.

What to do if my Pentair Water Filtration System has excessive water in the brine tank and/or salty water to service?
- M
  Michael MillerAug 27, 2025
  If you notice excessive water in the brine tank or salty water being delivered, there might be a plugged drain line. Check the flow to the drain and clean the flow control. Another possible cause is a dirty or damaged brine valve, which should be cleaned or replaced. Also, inspect the injector for any blockages; clean the injector and replace the screen if necessary. Ensure that the inlet pressure is at least 1.4 bar to allow the injector to function correctly. Finally, if the timer isn't cycling, consider replacing the controller.

  jonathangarciaAug 27, 2025
  A loss of water pressure in your Pentair Water Filtration System can occur due to scaling or fouling of the inlet pipe. Clean or replace the pipeline and consider pretreatment to prevent future occurrences. Fouled resin can also cause this issue; clean the resin and pretreat to prevent it from happening again.

What causes poor water quality in my Pentair Water Filtration System?
- J
  Joe MccoyAug 28, 2025
  Poor water quality from your Pentair Water Filtration System may be due to an open bypass valve; ensure it is closed. Channeling can also cause this, so check for service flow that is either too slow or too high, and inspect for media fouling. Finally, verify that the mixing is set correctly.

What causes a Pentair Water Filtration System to fail to regenerate automatically?
- T
  Tabitha MorrisAug 31, 2025
  If your Pentair Water Filtration System fails to regenerate automatically, it could be due to several reasons: * The cord is plugged into an intermittent or switched-off power source; connect it to a constant power source. * The meter cable is disconnected or faulty; reconnect or replace the cable. * The power cord is defective; replace the cord. * The controller, meter, or sensor is defective; replace or repair them. * The programming is incorrect; program it correctly.

Why does my Pentair Water Filtration System have a loss of capacity?
- W
  whitesarahSep 1, 2025
  A loss of capacity in your Pentair Water Filtration System can be attributed to several factors. Increased raw water hardness may be the cause; if so, reset the unit to the new capacity. Ensure the brine tank is full of salt at all times and clean it yearly to maintain proper brine concentration and quantity. Salt may be bridged. If you're using a salt grid plate, make sure the refill water is above it.
