1 12 hp pump runs fine but sputters every few seconds why?

#### 1. Suction Issues:

- Check the suction line for any air leaks, kinks, or blockages.

- Ensure that the foot valve is properly installed, and the pump is getting a steady supply of water.

#### 2. Air in the Pump:

- Air can get trapped in the pump, causing it to sputter.

- Try bleeding the air out by loosening a plug or a bleed valve on the pump.

#### 3. Low Water Level:

- If the water level in the source is too low, the pump may not be able to draw water efficiently, leading to sputtering.

- Ensure that the water level is adequate and the pump is submerged as per manufacturer's instructions.

#### 4. Clogged Filter:

- Check the filter screen on the pump inlet for any debris or dirt that might be blocking the water flow.

- Clean or replace the filter as needed.

#### 5. Faulty Check Valve:

- A faulty check valve can cause the pump to lose its prime, leading to sputtering.

- Inspect the check valve for damage or debris, and replace it if necessary.

#### 6. Worn Impeller:

- A worn impeller can cause the pump to lose efficiency and sputter.

- Inspect the impeller for damage or excessive wear, and replace it if necessary.

#### 7. Electrical Issues:

- Check the electrical connections to ensure they are tight and secure.

- If the pump is overheating or not getting sufficient voltage, it can cause intermittent operation.

#### 8. Pump Cavitation:

- Cavitation occurs when the pump operates at a higher speed than the available water supply.

- Reduce the pump speed or check the water supply to eliminate cavitation.

#### 9. Faulty Motor:

- If the motor of the pump is not functioning properly, it can lead to sputtering or inconsistent operation.

- Check for any signs of damage or overheating and consider getting the motor repaired or replaced.

Note: If the sputtering persists after addressing these potential issues, it's recommended to consult a professional for further assistance and ensure the safety and longevity of your pump.
