  If the Neptun Water System experiences an inadequate delivery rate, there could be several reasons. The suction height might be too high, so check it. The strainer could be dirty, requiring cleaning. If the water level is falling rapidly, try placing the suction hose at a deeper level. Contaminants might have diminished the pump's performance; in this case, clean the pump and replace any worn parts.

  If the thermostat switches off the Neptun Water System pump, it may be due to an overloaded motor, so dismantle and clean the pump. It could also be due to excessive friction caused by foreign substances; prevent the intake of foreign substances by using a filter.
