What to do if my Pentair Water Filtration System softener fails to draw brine?
- A
  Amanda BanksAug 16, 2025
  If your Pentair Water Filtration System softener fails to draw brine, start by checking and cleaning the drain line flow control, injector, and injector screen to ensure they are free of obstructions. Ensure that the line pressure is at least 20 psi. If these steps don't resolve the issue, there may be an internal control leak, requiring the seals, spacers, and piston assembly to be changed. Also, verify that the service adapter cycled; check the drive motor and switches.

Why is my Pentair Water Filtration System producing hard water?
- J
  Jordan DiazAug 19, 2025
  If your Pentair Water Filtration System is producing hard water, several factors could be at play. First, ensure the by-pass valve is closed. Check that there is enough salt in the brine tank, maintaining the salt level above the water level. Also, the injector screen might be plugged, so clean it. Insufficient water flowing into the brine tank could be another reason; check the brine tank fill time and clean the brine line flow control if it's plugged. If you have a hot water tank, repeated flushing might be required to address hardness. Inspect the distributor tube for cracks and check the O-ring and tube pilot. Finally, an internal valve leak could be the culprit, requiring replacement of seals, spacers, and/or the piston.

  If your Pentair Water Filtration System fails to regenerate, there could be several reasons. First, ensure the unit has permanent electrical service by checking the fuse, plug, pull chain, or switch. If the electrical service is ok, the timer might be defective and need replacement. Also, check if there was a recent power failure, and if so, reset the time of day.

Why am I experiencing a loss of water pressure with my Pentair Water Filtration System?
- X
  Xavier DeleonAug 28, 2025
  If you're experiencing a loss of water pressure with your Pentair Water Filtration System, it might be due to iron buildup. Try cleaning the line to the water conditioner. If that doesn't work, clean the control and add mineral cleaner to the mineral bed, and increase the frequency of regeneration. Also, the inlet of the control might be plugged due to foreign material; remove the piston and clean the control.

- V
  veronica47Sep 9, 2025
  If you find iron in the conditioned water from your Pentair Water Filtration System, the mineral bed may be fouled. Check the backwash, brine draw, and brine tank fill. You might need to increase the frequency of regeneration and the backwash time.

Why does the drain flow continuously in my Pentair Water Filtration System?
- M
  Michael BrowningSep 12, 2025
  If the drain of your Pentair Water Filtration System flows continuously, the valve may not be programming correctly. Check the timer program and positioning of the control. Replace the power head assembly if it is not positioning properly. Also, there could be foreign material in the control; remove the power head assembly and inspect the bore, removing any foreign material and checking the control in various regeneration positions. Finally, there could be an internal control leak, requiring replacement of the seals and piston assembly.
