Troubleshooting your Davey Pump

 

A machine of any kind doesn’t stand for a lifetime and you have to consider replacing them after a particular period. Just like any other equipment present in your home, your Davey pump might be showing symptoms of having a bad time running. You will see Davey Pumps Australia-wide, used in homes, offices and other commercial settings, but the question that arises is how you should check whether your pump has problems or not.

Here are some of the common problems that you might have faced or face in future, the reasons behind and possible solutions:

Motor runs when switched on but does not pump

If the motor runs and produces the sound of running but there are no results of water pumping, here are some issues that might be occurring inside:

·         The pump body and the suction line isn’t filled with water

·         Air leaks in suction lines and pipes underwater

·         Closed valves on suction lines

·         Impeller is blocked

·         Water level or pressure low or no water at the source

Pump switches on and off frequently

If you report that your pump is switching on and off. Here are some potential reasons and solutions:

• Make sure to check that the tank air charge is showing a constant of 130 kpa.
• There might be leaks in the float switch, valves or the taps
• Leaks might be in the valves/foot valves

The motor doesn't start when switched on

• Internal motor fault (blown capacitor)
• Supply voltage too low
• Power not connected
• Motor not free to turn, jammed impeller
• Over-temperature

 The pump does not start

Here are some potential reasons if your pump isn’t starting at all.

• No power or electricity. Make sure that the pump is connected properly. Also check the fuse, wire, breakers or circuit for any damage
• Pressure controller showing there is no water present in the tank. In such cases, check if there is enough water present in the tank or not. If yes then reset the controller.
• A capacitor is defective. The capacitor in your pump might be having issues, replace the capacitor in the electric motor.

 The pump is not stopping even when all the taps are shut

In cases where the pump isn’t shutting down even when there is no tap open, one potential reason is that there is debris inside the pressure controller. To solve this, you have to inspect the controller for any foreign matter. Also, there might be leaks in the plumbing. So, you have to fix the leaks to solve the issue.

No water from the pump at all

• The pump might not be primed. Make sure that the suction line and the pump body is filled before starting
• A suction-line might be leaking. So, check if there are any leaks in the suction, especially at the joints.
• Blockages in discharge or pump body. To avoid or solve, disconnect the pump from the main power outlet and check the discharge or pump housing for stimulus matter
• Closed valve, make sure that all the valves of pump, tank and outlets are checked properly.
• Insufficient water in the tank to pump. First, make sure that there is enough water in the tank and after that reset or restart the pump with the help of a controller.
• The pump isn’t producing the required pressure. Check and clean the pump to avoid such an issue
• Taps or in-line filters are blocked. Filters need cleaning if such an issue occurs.
