What to do if my Pentair Control Unit will not draw brine?
- R
  Ray TaylorAug 18, 2025
  If the Pentair Control Unit isn't drawing brine, several factors could be at play. First, check if the water pressure is low and adjust accordingly. A restricted drain line could also be the culprit, so remove any obstructions. Inspect the injector for blockages and clean the injector and screen. If the injector is defective, replace it along with the cap. Ensure valve disc 3 is closing properly by removing any foreign matter; if the disc is damaged, replace it. Lastly, check if the air check valve is prematurely closed; if so, momentarily put the controller into brine refill cycle. If needed, replace or repair the air check.

Why is my Pentair AUTOTROL Performa 268 leaking hard water after regeneration?
- T
  Teresa CollinsAug 20, 2025
  If you're experiencing hard water leakage after regeneration with your Pentair Control Unit, it could be due to several reasons. Start by checking the brine dosage setting and repeat the regeneration process. If you have an external bypass valve, check for leaks and replace if necessary. Inspect the O-ring around the riser pipe for damage and replace if needed. Finally, verify that the brine amount and system capacity are appropriate for your system.

Why am I running out of conditioned water between regenerations with my Pentair AUTOTROL Performa 268 Control Unit?
- A
  Ashley MooreAug 23, 2025
  If you're running out of conditioned water between regenerations with your Pentair Control Unit, start by ensuring proper regeneration settings. Verify the brine setting is at the correct level. Also, confirm that the hardness and capacity settings are accurate. If your water hardness has increased, adjust the setting accordingly. Finally, check for any restrictions in the meter turbine rotation due to foreign matter; clean the turbine and flush with clean water, replacing the meter if necessary.

What causes brine tank overflow in a Pentair AUTOTROL Performa 268 and how to fix it?
- C
  Connie GayAug 26, 2025
  If your Pentair Control Unit's brine tank is overflowing, several issues might be the cause. First, check for uncontrolled brine refill flow rate. Remove the brine controller to clean the ball and seat. Also, inspect the brine line for air leaks. Check all connections in the brine line. Finally, ensure that the drain control isn't clogged with resin or other debris and clean it if necessary.

  If the brine tank of your Pentair Control Unit is overflowing, it could be due to several reasons. Check if the brine valve disc 1 is being held open by foreign matter and manually operate the valve stem to flush away any obstructions. Inspect the brine line for air leaks, ensuring all connections are secure. Verify that the drain control is appropriate for the injector; a small drain control with a larger injector can reduce draw rates. Lastly, check for and clean any resin or debris clogging the drain control.

  If you're not getting conditioned water after regeneration with your Pentair Control Unit, ensure there is brine in the brine tank by adding some. Also, check the injector for clogs and clean the injector and screen. If the air check valve closes prematurely, momentarily put the controller into the brine cycle. If needed, replace or repair the air check.

Why is there flowing or dripping water at the drain or brine line after regeneration in my Pentair AUTOTROL Performa 268 Control Unit?
- A
  Angel CookSep 4, 2025
  If you notice water flowing or dripping at the drain or brine line after regeneration in your Pentair Control Unit, it might be because the valve stem return spring is weak; in this case, replace the spring. Another reason could be debris preventing the valve disc from closing properly, so remove any debris.

What causes excessively low or high backwash/purge rates in a Pentair AUTOTROL Performa 268 Control Unit?
- P
  Philip MatthewsSep 7, 2025
  If your Pentair Control Unit backwashes or purges at an excessively low or high rate, it could be due to an incorrect drain control being used; replace it with the correct size controller. Also, foreign matter affecting valve operation may be the cause; remove the drain control and clean the ball and seat.

Why is there no water flow display on my Pentair 760 Control Unit when water is flowing?
- T
  Terry GraySep 9, 2025
  If your Pentair 760 Control Unit isn't displaying water flow despite water flowing, first check if the bypass valve is in the bypass position and shift it to the non-bypass position. Then, ensure the meter probe is fully inserted into the meter housing. Lastly, check for any restrictions in the meter turbine rotation due to foreign matter; remove the meter housing, free up the turbine, and flush with clean water. If the turbine doesn't spin freely, replace the meter.
