  If your Neptun Water Pump isn't taking in water, several issues could be the cause. First, ensure the intake valve is fully immersed in water. Next, check that the pump chamber has a water connection and that you have filled water into the intake. Make sure the intake line is airtight. Also, inspect the intake valve for leaks and clean it if necessary. Clean the strainer if it's blocked. Finally, verify that the maximum suction height hasn't been exceeded.

  If your Neptun Water Pump has an inadequate delivery rate, consider these potential causes. Check if the suction height is too high. Also, the strainer might be dirty and needs cleaning. If the water level is falling rapidly, place the suction hose at a deeper level. Contaminants might have diminished the pump's performance, so clean the pump and replace any worn parts.

  If the thermostat is switching your Neptun Water Pump off, it could be due to an overloaded motor. Dismantle and clean the pump. Another possible reason is excessive friction caused by foreign substances. Prevent the intake of foreign substances by using a filter.
