    What to do if my Pentair Water Filtration System is leaking water?
    • A
      anitabondAug 16, 2025
      If your Pentair Water Filtration System is leaking, there are several potential causes. First, inspect the O-ring seal on the retaining nut and/or UV sensor. Ensure the O-ring is correctly placed, check for any cuts or abrasions, clean it, moisten it with water or a lubricant, and then reinstall it. Replace the O-ring if necessary. Another cause may be condensation on the chamber due to excessive humidity and cold water. In this case, check the location of the disinfection system and control the humidity. Finally, check the inlet/outlet port connections for inadequate sealing. Reseal the thread connections with Teflon® tape and re-tighten them.

    What to do if my Pentair Water Filtration System displays a blank LED?
    • M
      Michael MaloneAug 22, 2025
      If the LED display on your Pentair Water Filtration System is blank, it could indicate that the controller is in lamp failure mode. Power the system down and allow it to reset itself. Then, reapply power to confirm if the controller can power the lamp. Also, check to ensure that there is sufficient power reaching the UV system. If needed, replace the lamps.

    How to fix high bacteria counts in Pentair VH200?
    • J
      Jesus FischerAug 26, 2025
      High bacteria counts in your Pentair Water Filtration System can be due to several reasons. You can clean the quartz sleeve with a scale cleaner and eliminate the source of the staining problem (e.g., soften hard water). Have your source water tested to ensure the water quality is still within allowable limits for the system. Ensure the effluent water stream is shocked with chlorine (bleach) before the water leaves the UV system. The disinfection system must have a bacterial-free distribution system to work effectively. Also, test source water for turbidity. You may need stepped filtration to catch all sediment entering the water system, using a 20-micron filter followed by a 5-micron filter before the UV system.

    Why does my Pentair Water Filtration System keep shutting down intermittently?
    • S
      Sabrina SmithAug 28, 2025
      If your Pentair Water Filtration System is shutting down intermittently, it may be due to an interrupted controller. Ensure the system is installed on its own circuit, as other equipment might be drawing power away from the UV system (e.g., a pump or fridge). The UV system should not be installed on a circuit that incorporates a light switch.

    What to do if the Pentair Water Filtration System lamp failure alarm is on with a new lamp?
    • G
      gsavageAug 31, 2025
      If the lamp failure alarm is on even with a new lamp in your Pentair Water Filtration System, first, disconnect the lamp from the connector and reconnect it, ensuring a tight fit. Moisture buildup in the connector may also prevent the lamp and connector from making a solid connection. Eliminate any chance of moisture getting to the connector and/or lamp pins.

    Why does the Pentair Water Filtration System produce heated product water?
    • S
      Samantha NelsonSep 3, 2025
      Heated product water in your Pentair Water Filtration System is commonly caused by infrequent use of water. Simply run the water until it returns to ambient temperature.

    Why does the water from my Pentair Water Filtration System appear milky?
    • S
      stacy25Sep 6, 2025
      If the water from your Pentair Water Filtration System appears milky, it is likely caused by air in the water lines. Run the water until the air is purged from the system.

    What does it mean when my Pentair Water Filtration System LED display reads “A3”?
    • A
      Ann CookSep 9, 2025
      When your Pentair Water Filtration System's LED display reads “A3”, it indicates that the lamp life has expired and the countdown is at “0” days. Replace the UV lamp.

    Why does my Pentair Water Filtration System have a pressure drop?
    • J
      John EatonSep 12, 2025
      A pressure drop in your Pentair Water Filtration System can occur for a couple of reasons. One common cause is a clogged sediment pre-filter. Replace the filter cartridge with an appropriate 5-micron cartridge. Also, check your source water supply for fluctuations in pressure. Another cause can be the flow regulator; it will result in a pressure drop when approaching full flow.

    What does it mean when the Pentair Water Filtration System LED is flashing “A2” and then back to UV level?
    • L
      lopezpaigeSep 12, 2025
      When the LED on your Pentair Water Filtration System is flashing “A2” and then reverts to the UV level, it signifies that a low UV alarm deferral has been activated. The UV level has dropped below 50%, and the audible alarm has been muted by pressing and holding the reset switch for 5 seconds. Note that this audible alarm deferral will only last for 12 hours.
