    What to do if there is excessive water in brine tank of Envirotec Water Dispenser?
    • A
      Austin Ramsey DVMAug 8, 2025
      If you notice excessive water in the brine tank of your Envirotec Water Dispenser, it could be due to several reasons: 1. The drain line flow control might be plugged. Try cleaning it and then put the system through a manual regeneration cycle. 2. The injector system could be plugged. Clean the injector and screen. 3. The timer may not be cycling. Consider replacing it. 4. There might be foreign material in the brine valve. Replace the brine valve seat and clean the valve. 5. Foreign material could be in the brine line flow control. Clean the brine line flow control. 6. There might have been a power loss during brine fill. Check the power source.

    How to fix loss of water pressure in Envirotec ET50H?
    • K
      Kevin TateAug 12, 2025
      If you are experiencing a loss of water pressure with your Envirotec Water Dispenser, consider the following: * Iron build-up might be present in the water softener. Clean the control, add resin cleaner, and increase the regeneration frequency and/or backwash time. * The inlet of the control could be plugged. Remove the piston and clean the control of any foreign material. * The resin might be fouled. In this case, replace the resin.

    Why Envirotec ET50H Water Dispenser uses too much salt?
    • C
      Courtney RamosAug 16, 2025
      If your Envirotec Water Dispenser is using too much salt, check the salt usage and salt setting. Also, excessive water in the brine tank could be the cause. This means the brine draw isn't functioning correctly, so clean or replace the injectors.

    What causes loss of resin media through drain line in Envirotec Water Dispenser?
    • J
      Jill SandersAug 21, 2025
      If you're experiencing loss of resin media through the drain line of your Envirotec Water Dispenser, it could be due to: * Air in the water system. Make sure your well system has a proper air eliminator control and check for a dry well condition. * The drain line flow control being too large. Check to ensure the drain line flow control is sized properly for your mineral tank.

    • J
      Jennifer AvilaNov 3, 2025
      If your Envirotec Water Dispenser isn't softening water, here are a few things to check: * Ensure the bypass valve is in the service position. * Make sure there's enough salt in the brine tank, above the water level. Wait an hour, then manually regenerate. * The injector screen may be plugged and require cleaning. * Check if enough water is flowing into the brine tank. If not, check the brine tank fill time and clean the brine line flow control if it's plugged. * Consider replacing seals, spacers, piston, or distributor if there's an internal valve leak. * If the hot water is hard, use enough hot water to turn over the tank with soft water. * Inspect the distributor tube for cracks and check the O-ring and tube pilot for leaks at the distributor tube. * If the system isn't...
