Why is my Pentair Water Filtration System delivering hard water?

  If your Pentair Water Filtration System delivers hard water, first, ensure the bypass valve is closed. Then, check the brine tank and add salt, maintaining the salt level above the water level. Inspect the injectors and screen for clogs and replace if necessary. Check the brine tank fill time and clean the brine line flow control if it's plugged. Repeatedly flush the hot water tank. Make sure the distributor tube isn't cracked and check the O-ring and tube pilot. Finally, consider replacing the seals, spacers, and/or piston due to a potential internal valve leak.

  Cindy BlackwellAug 22, 2025
  If your Pentair Water Filtration System has a loss of water pressure, start by cleaning the line to the water conditioner to remove any iron build-up. If the issue persists, clean the control and add resin cleaner to the resin bed, while also increasing the frequency of regeneration. If the inlet of the control is plugged due to foreign material, remove the piston and clean the control.

  If your Pentair Water Filtration System fails to regenerate, ensure that it has permanent electrical service by checking the fuse, plug, pull chain, or switch. If the electrical service is fine, then the timer may be defective and require replacement. Also, in case of a power failure, reset the time of day.

Why does my Pentair Water Filtration System fail to draw brine?

  ashleycamposAug 30, 2025
  If your Pentair Water Filtration System fails to draw brine, the first step is to clean the drain line flow control. If that doesn't resolve the issue, clean or replace the injectors. Also, replace the screen. Ensure that the line pressure is adequate, maintaining a minimum of 20 psi (1.3 bar) at all times. If problems persist, consider changing the seals, spacers, and/or piston assembly due to a potential internal control leak.
