Why is there no suction of solution in my dosatron D25RE2 Water Filtration Systems?
- C
  crossJul 27, 2025
  Several factors can cause a lack of suction. The piston might be locked; try resetting it. There could be an air leak in the suction tube, so check the connections, inspect for damage, ensure tightness, and trim the hose end. The suction tube or strainer could be clogged, requiring cleaning or replacement, and ensure the strainer is raised off the bottom of the solution container. A check valve might be worn, dirty, or damaged, needing cleaning or replacement. The plunger seal may be damaged, swollen, or missing, requiring attention or replacement. Lastly, worn piston components could be the culprit; consider a piston 'fit' test and replacement if necessary, while ensuring a 200 mesh filter is installed before the dosatron.

How to fix a dosatron D25RE2 Water Filtration Systems piston that is not clicking?

  A piston that isn't clicking can stem from several issues. First, ensure the unit is installed correctly, with the arrow matching the water flow direction, and that water supply valves are open. The piston may be locked, requiring a reset. A broken actuator spring necessitates replacement. Excessive water flow requires reducing the flow rate and checking the piston O-rings. Water hammer may also be the cause, needing a piston reset and installation of a water hammer arrestor. A clogged in-line water filter should be cleaned. Lastly, worn piston parts may need replacement after performing a 'fit' test, and ensure a 200 mesh filter is installed before the dosatron.

What to do if my dosatron Water Filtration Systems is under-injecting solution?
- D
  dhardingAug 4, 2025
  Under-injection can occur due to several reasons. The piston shell and/or body might be worn or scratched, requiring a 'fit' test and possible replacement. Air suction could be happening; inspect the suction tube for leaks and ensure tight connections. Excessive water flow can also cause this, so monitor the unit's clicking (should not exceed 46 clicks in 15 seconds) and reduce flow if needed. A worn plunger seal or a worn/cracked injection stem (inside or outside) may need replacement. Finally, a worn, improperly assembled, dirty, or damaged check valve should be cleaned or replaced.

  If water is flowing back into the solution container, the check valve is likely dirty, worn, incorrectly assembled, or missing. Try cleaning or replacing the check valve assembly.
