    What to do if RO pump will not stay on in my WET ES Water Filtration Systems?
    • C
      Cheyenne TrevinoAug 3, 2025
      If the RO pump in your WET Water Filtration System isn't staying on, it could be due to several reasons: * Low supply water pressure to the RO unit, indicated by a "LOW PRESSURE" light. Check the 5-micron pre-filter and clean or replace it. * High pH or conductivity. Check the feedwater supply. * The "HIGH PRESSURE" light is on. Adjust the pump throttle and reject valves. * The instrumentation is not reading correctly. Calibrate or replace the defective instrument.

    What to do if my WET Water Filtration System is making too much water?
    • C
      charlesdennisAug 12, 2025
      If your WET Water Filtration System is producing too much water, consider these potential causes: * The reject valve might be closed too far. Open the reject valve and set it to the operating specifications. * The water temperature may have increased. Control the water temperature to stay within the RO unit design limits. Higher water temperature allows more water to pass through the membrane element, while lower temperatures reduce the amount of water passing through.

    Why RO pump runs but no product water is being delivered to service in WET ES?
    • H
      Hannah MontgomeryAug 18, 2025
      If the RO pump in your WET Water Filtration System runs but no product water is delivered, check these: * The reject valve is open too far. Adjust the pump throttle and reject valves. * The flush/clean tank is not yet full. Wait for the tank to fill. * There's a blockage in the product lines. Check the product water line for blockages. * The reject flush pneumatic valve is not closed. Check for flow through the valve and replace it if defective.

    What causes high conductivity in WET Water Filtration Systems?
    • D
      debbiefletcherAug 23, 2025
      High conductivity in WET Water Filtration Systems can stem from: * A recovery ratio that is too high. Reduce the recovery ratio to within RO design limits by adjusting the pump throttle and reject valves. * A TDS indicator or probe that isn't functioning properly. Inspect and service the TDS instrument as needed.

    Why is my WET Water Filtration System not making enough water?
    • J
      Jennifer ElliottOct 28, 2025
      There are several reasons why your WET Water Filtration System might not be producing enough water: * The flush fill valve might be open. Wait for the high limit sensor to indicate a full tank. If the valve doesn't close, check the sensor operation and wiring. * The water temperature might be too low. Production drops 2% for every degree below 77 degrees F. Control the water temperature to stay within the RO unit design limits. * There may be low supply water pressure to the RO unit. Check the 5-micron pre-filter, clean or replace it. Also, check the supply pressure to the 5-micron pre-filter. * The RO membranes could be fouled. Clean the RO membranes. * The RO pump pressure might be low. Increase the RO pump pressure by adjusting the pump throttle and reject valves. * The pro...

    Why is product water conductivity too high in my WET ES?
    • B
      Brittany TorresNov 7, 2025
      High product water conductivity in your WET Water Filtration System can be caused by: * An O-ring bypass in the reverse osmosis membrane vessel. Remove the membrane element from the housing and inspect the O-rings, ensuring they are seated properly. If performance doesn't improve, replace the membrane element. * Chlorine damage to the membrane element. Replace the membrane element. * The reverse osmosis membrane being fouled. Clean the membrane element(s), and replace them if cleaning doesn't restore performance. * Increased feedwater TDS since installation. This is normal and cannot be adjusted; higher feedwater TDS leads to higher TDS in the product water. * High or low pH level in the feedwater. Control the pH level to stay within the RO unit design limits. If the pH level is...
