  If your Central Machinery Water Pump won't start, there might be several reasons. First, check the power connections to ensure they are properly connected. Also, the impeller may be blocked, in which case you should free the motor shaft. Another possible cause is a disconnected pressure switch, so inspect the gauge. Finally, the thermal protection might have cut out; if so, allow the pump to cool down.

  If your Central Machinery Water Pump operates but doesn't discharge water, several factors could be at play. Ensure the inlet tube is fully submerged. Also, check the pipe and seals for any air in the suction pipe. A clogged inlet screen can also prevent discharge, so clean the screen. Lastly, reducing the lifting height may resolve the issue if it has been exceeded.

  If your Central Machinery Water Pump has low capacity, consider these potential causes: The inlet pipe might be too small, so try increasing the pipe diameter. If the liquid is too dirty, clean the screen frequently. Also, reducing the lifting height may help if it has been exceeded. Lastly, ensure the tank’s rubber bladder is properly inflated to 21-29 PSI.
