  If your Riva-flo Water Pump doesn't start, first ensure it's properly connected to a working power outlet. Then, inspect the circuit breakers and fuses. If the pressure controller indicates low water, ensure the tank has sufficient water and press the 'reset' or 'start' button. Also, disconnect the pump and check for any blockages in the housing and discharge. If none of these steps work, the capacitor might be defective, and you should call a qualified service technician.

  If you're getting no water from your Riva-flo Water Pump, start by ensuring the pump body and suction line are filled with water before starting. Check the suction line for any leaks, especially at the joints. Disconnect the pump from power and inspect the pump housing and discharge for blockages. Make sure all valves on the tank, pump, and outlets are open. If the tank doesn't have enough water, wait until there is more water and then press the ‘reset’ or ‘start’ button on the pressure controller. Check and clean the pump. Also, check the system pressure and adjust the pressure switch accordingly. Finally, clean any blocked in-line or tap filters.

Why Riva-flo GP40 will not stop, even though there is no taps open?

  If your Riva-flo Water Pump won't stop running even when all taps are closed, it could be due to debris caught in the pressure controller, in which case, take the pressure controller to your dealer for service. Alternatively, there might be leaks in your household plumbing, so locate and fix any leaks.
