Why does my Clack Valves WS1.5 Water System regenerate at the wrong time?
- M
  Michelle SpearsAug 25, 2025
  If your Clack Valves Water System control valve regenerates at the wrong time, here's what to check: * A power outage may have occurred. Reset the time of day. If the PC Board has a battery back up, the battery may be depleted. * The time of day might not be set correctly. Reset it to the correct time. * The time of regeneration might be set incorrectly. Reset the regeneration time. * The control valve might be set at "on 0" (immediate regeneration). Check the programming setting and reset to NORMAL (for a delayed regen time). * The control valve might be set at "NORMAL + on 0" (delayed and/ or immediate). Check the programming setting and reset to NORMAL (for a delayed regen time).

  Bianca JohnsonAug 27, 2025
  If you find excessive water in the regenerant tank of your Clack Valves Water System, consider the following: * Improper program settings. Check the refill setting. * A plugged injector. Remove the injector and clean or replace it. * The drive cap assembly not tightened properly. Re-tighten the drive cap assembly. * A damaged seal/ stack assembly. Replace the seal/ stack. * A restricted or kinked drain line. Check the drain line for restrictions or debris, and/or un-kink the drain line. * A plugged backwash flow controller. Remove the backwash flow controller and clean or replace it. * A missing refill flow controller. Replace the refill flow controller.

Why is water constantly running to drain in my Clack Valves Water System?
- V
  Valerie AcostaAug 31, 2025
  If water is constantly running to the drain in your Clack Valves Water System, it could be due to: * A power outage during regeneration. Once power is restored, the control will finish the remaining regeneration time. Reset the time of day. * A damaged seal/ stack assembly. Replace the seal/ stack assembly. * Piston assembly failure. Replace the piston assembly. * The drive cap assembly not tightened properly. Re-tighten the drive cap assembly.

What causes a Clack Valves Water System control valve to fail to draw in regenerant?
- A
  alisha36Sep 2, 2025
  If your Clack Valves Water System's control valve isn't drawing in regenerant, check these potential causes: * The injector is plugged. Remove the injector and clean or replace it. * The regenerant piston is faulty. Replace the regenerant piston. * There's a leak in the regenerant line connection. Inspect the regenerant line for an air leak. * The drain line has a restriction or debris causing excess back pressure. Inspect the drain line and clean to correct the restriction. * The drain line is too long or too high. Shorten the length and/or height. * The water pressure is low. Check the incoming water pressure – it must remain at a minimum of 25 psi.

Why is my Clack Valves Water System delivering residual regenerant?
- R
  Rachel WrightSep 4, 2025
  If your Clack Valves Water System is delivering residual regenerant to the service, consider the following: * Low water pressure. Check the incoming water pressure – it must remain at a minimum of 25 psi. * Incorrect injector size. Replace the injector with the correct size for the application. * Restricted drain line. Check the drain line for restrictions or debris and clean it.

Why does my Clack Valves Water System display not indicate water flow?
- M
  Monica GonzalezSep 5, 2025
  If the display on your Clack Valves Water System isn't showing that water is flowing, check these items: * The bypass valve is in the bypass position. Turn the bypass handles to place the bypass in the service position. * The meter isn't connected to the meter connection on the PC Board. Connect the meter to the three-pin connection labeled METER on the PC Board. * The meter turbine is restricted or stalled. Remove the meter and check for rotation or foreign material. * The meter wire isn't installed securely into the three-pin connector. Verify the meter cable wires are securely installed into the three-pin connector labeled METER. * The meter is defective. Replace the meter. * The PC Board is defective. Replace the PC Board.

What does error 1004 mean on Clack Valves WS1.5 Water System?
- T
  taylorderrickSep 12, 2025
  If your Clack Valves Water System displays error Err – 1004 or Err – 104, indicating the control valve motor ran too long trying to reach the home position, check the following: * Ensure the drive bracket is snapped in properly so that the reduction gears and drive gear interface correctly. Snap the drive bracket in properly, then press the NEXT and REGEN buttons for 3 seconds to resynchronize the software with the piston position, or disconnect the power supply from the PC Board for 5 seconds and then reconnect.
