      Louis HoweAug 15, 2025
      If your DOSATRON Water Pump doesn't start or stop, it could be due to several reasons: * The piston might be stalled, in which case you should reset it by hand. * The by-pass might be either in the OFF position or half opened. Place the by-pass lever in the ON position. * The maximum flow might be exceeded. Reduce flow and restart the DOSATRON. Also, check piston valves seals to ensure correct position. * The motor piston is damaged. Return unit to your DOSATRON service center for repair.
