Why is the pump repeatedly running in short bursts in flamco Midi 125D Portable Generator?
- W
  wjordanSep 6, 2025
  If your Flamco Portable Generator's pump is repeatedly running in short bursts, it could be due to: * The internal isolation valve within the unit being partially closed. Fully open it. * Too much restriction in the connecting pipe work. Increase bore, reduce bends, or reduce length. * A pump non-return valve has failed, replace it. * The expansion vessel has failed or lost its pre-charge, check and re-charge if necessary. * The unit's connection point is too far from the expansion vessel. Move them closer.
