What to do if my Lakos Water Filtration System has a consistently high pressure differential?
- E
  Eric LoweryAug 18, 2025
  A consistently high pressure differential in your Lakos Water Filtration System may be due to: * Excessive contaminant load restricting flow through the filters and preventing sufficient flow for backwashing. Drain the tank, remove the manway access ports, carefully skim away any excess or caked contaminants from the media sand bed’s surface, and then return the tank to normal service and backwash the system. * Insufficient backwash flow. Check the backwash valve linkage for proper operation. * Inadequate media sand volume, which may minimize coverage of backwash flow across the filter bed, creating dead spots of accumulated contaminants. Add sand media as necessary.

What to do if Lakos Water Filtration system 'trips' out when running and shuts down?
- A
  Antonio PerezAug 22, 2025
  If your Lakos Water Filtration System trips and shuts down, consider these potential causes: * The overload setting might be too low. Check the overload setting in the control panel, ensuring it's just above the full load amp value on the motor nameplate. * The supply voltage could be incorrect. Verify the incoming supply voltage against the STS system power requirements located on the control panel door (both outside and inside). * The system flow might be too high. Install a valve on the system discharge to control the flow. * A loose wire could be the culprit. Inspect all wires for loose connections.

Why won't my Lakos Water Filtration System pump prime?
- S
  Susan JonesAug 25, 2025
  If your Lakos Water Filtration System pump won't prime (standard, not self-priming), it might be because: * The suction line isn't flooded with water. Check and clean out the pump suction pre-strainer as required. * There's debris in the basket strainer. Check and clean the pump pre-strainer as required. * There are air leaks. Check and tighten all connections as required. * The pump is rotating in the wrong direction. Check the pump rotation against the motor rotation arrow and rewire if necessary for proper rotation.

How to fix a Lakos Water Filtration System backwash valve leak?
- M
  Michael AndersonAug 28, 2025
  A leaking backwash valve in your Lakos Water Filtration System could be due to: * An obstruction in the valve seat. Remove the obstruction. * Worn or damaged rubber seating. Replace the valve. * A damaged actuator diaphragm. Replace the diaphragm. * Linkage out of adjustment. Adjust the linkage.

Why does my Lakos Water Filtration System pump motor run hot?
- S
  Shawn HenrySep 1, 2025
  A Lakos Water Filtration System pump motor may run hot due to: * The motor being located in direct sunlight. Cover the motor with some type of sun shade if possible. * Poor ventilation. Ensure the motor has a fresh source of air for cooling, as all motors require air movement for cooling. * Low voltage. Check the voltage with a meter.

What causes water hammer in a Lakos Water Filtration System?
- J
  Jamie SmithSep 4, 2025
  Water hammer in a Lakos Water Filtration System can be caused by: * Air in the tanks. Bleed off trapped air in the system. An air vent on the system may be required. * A long backwash line causing a vacuum. Install a vacuum breaker on the backwash line.

Why is media sand appearing downstream in my Lakos Water Filtration System?
- A
  Amber VanceSep 7, 2025
  Media sand appearing downstream in your Lakos Water Filtration System could be due to: * Incorrect media sand (i.e., too fine and too small). Replace the media with properly sized media. * Broken, damaged, or missing lateral. Repair or replace the laterals of the underdrain.

Why does the automatic backwash on my Lakos Water Filtration System fail to cycle?
- L
  Linda SmithSep 12, 2025
  The automatic backwash failing to cycle on your Lakos Water Filtration System could stem from: * Controller power being off or circuit fuses tripped. Ensure wiring is correctly connected, replace circuit fuses, and turn on the power. The controller may be faulty and need replacement. * Improper setting of the differential switch. Adjust as necessary. * Actuator malfunctioning. Check connections.

Why is the Lakos Water Filtration System experiencing poor filtration?
- V
  vcarterNov 14, 2025
  Poor filtration in your Lakos Water Filtration System can occur due to several reasons: * Excessive flow through the filters can cause “coning” of the media sand, forcing contaminants through the filter outlet. Installing a throttling valve can help control the flow. * Air trapped in the tank(s) may disrupt the media sand bed. Bleeding off trapped air in the system can resolve this. * Using incorrect media sand can lead to poor filtration. Replace it with the proper media sand. * Excessively high pressure differential before backwashing can force contaminants through the filter bed. Backwash more often at a lower differential pressure to prevent this. * Insufficient media volume in the filter can allow contaminants to pass through. Add the proper sand media to the tank(s) to the...
