How to fix inadequate backwash of filter in Culligan Water Filtration System?
- D
  dianacoxAug 16, 2025
  If you experience inadequate backwash of the filter in your Culligan Water Filtration System, it could be due to several reasons. The drain line flow control might be plugged, in which case you should clean or replace it. Another reason may be insufficient water supply from the well, so check for minimum specified flow and pressure requirements of the filter system. The inlet strainer could also be plugged, especially if there's nuisance bacteria present; clean the inlet strainer assembly and shock treat the water supply with chlorine as needed to control iron bacteria. Finally, the media bed might be fouled, requiring you to rebed the filter and correct the cause of fouling.

What to do if my Culligan Water Filtration System is running to drain continuously?
- A
  Andrew PadillaAug 19, 2025
  If your Culligan Water Filtration System is running water to drain continuously, ensure it has continuous electrical service by checking the plug, breaker, and fuse. If the electrical supply is fine, the circuit board or the drive motor may be faulty, requiring replacement. Also, foreign material may be lodged in the piston. In this case, disassemble and clean the control valve, and replace seals, spacers, and piston assemblies.

Why my Culligan Water Filtration System fails to recondition?
- C
  Cody WernerAug 22, 2025
  If your Culligan Water Filtration System fails to recondition, first ensure that it has a continuous electrical supply by checking the plug, breaker, and fuses. If the power supply is stable, the circuit board or drive motor may be faulty, requiring replacement. Alternatively, the circuit board settings might be incorrect, so try resetting it.

What to do if I notice air spurting from filtered water fixtures in my Culligan Water Filtration System?
- B
  brianbrowningAug 26, 2025
  If you notice air spurting from your filtered water fixtures with your Culligan Water Filtration System, it could be due to a service flow demand that exceeds the water supply available from the well pump system, requiring you to repair or replace the well pump system. Alternatively, water flow might be restricted by supply piping or water treatment equipment. Try to eliminate restrictions in supply piping to water treatment equipment such as iron bacteria plugging the upper diffuser assembly, etc.

Why is there inadequate aeration in my Culligan Water Filtration System?
- L
  lauren11Aug 27, 2025
  If you are experiencing inadequate aeration with your Culligan Water Filtration System, it could be due to a loss of air through the inlet check valve. Check the installation position of the check valve. Air loss through an air leak is another possible cause; inspect the filter tank, control valve, air suction line, check valve, and fittings for air leaks and repair them. Soapy water solution works well for locating air leaks. High demand can also cause air loss, so try increasing the reconditioning cycle frequency of the filter.

Why am I getting air spurting at outside or non-filtered water fixtures with my Culligan Water Filtration System?
- M
  Mrs. Vanessa ArcherAug 31, 2025
  If you notice air spurting at outside or non-filtered water fixtures, it may be due to improper installation location. Also, foreign material may be preventing the check valve from seating properly, so clean or replace the check valve. It may also be caused by a worn or faulty check valve, so replace the check valve.

Why is my Culligan Water Filtration System losing media through the drain line?
- D
  desireefisherSep 3, 2025
  If you are losing media through the drain line in your Culligan Water Filtration System, it could be because the new filter media was loaded dry in the filter tank. Clean the drain line flow control, control valve body, seals, spacers, and piston assemblies. Alternatively, air might be passing through the filter during backwash. Check programmed settings to ensure proper air draw cycle.

Why is my Culligan Water Filtration System making excessive noise during the reconditioning cycle?
- B
  Brian WyattSep 6, 2025
  If your Culligan Water Filtration System is experiencing excessive noise during the reconditioning cycle, it could be due to an inadequate drain line size, so increase the drain line size. Another cause could be the drain line vibrating against other pipes, conduits, pipe hangers, heat ducts, floor joists, etc., so insulate the drain line, specifically at points of contact with other materials.

What causes blue green staining from my Culligan Water Filtration System?
- D
  Damon PriceSep 8, 2025
  If you're seeing blue-green staining, it may be due to a low pH condition of the raw water supply.
J
Jamie StewartSep 12, 2025
What happens if I am exceeding recommended filter system flow rate with Culligan Water Filtration System?
- T
  tmortonSep 12, 2025
  If you are exceeding the recommended filter system flow rate with your Culligan Water Filtration System, it is because the service flow rate demand is higher than the filter system design flow rate. Install a flow control at the filter system outlet equal to or less than the design flow rate of the filter system.
