Troubleshooting an Electric Water Pump

An electric water pump is a common requirement in mant modern homes. However, it sometimes gives minor troubles for which you need to call up the plumber and shell out quite a few bucks. This can be saved if you keep in mind some simple and easy tricks for troubleshooting the water pump by yourself.

Tip 1: Priming Difficulties

Sometimes the pump does not start if you try to prime up. In this case, see if the pump hoses have any holes in them. Make sure that the seals are intact and that the check and other valves are in perfect working order. Sometimes due to wearing out of the pump parts, there is water seepage and the suction is hindered causing the air in the pipes to leak out. Check for clogging in the pipes from time to time as well. Check if the water temperature is too high. Extremely warm water sometimes causes problems, while priming the pump.

Tip 2: Impeller Placement

Trouble often rises due to the impeller being placed too close to the pump body. See the pump manual to locate its position and replace it if there is a fault in its placement.

Tip 3: Weak Flow

If the water flow is not sufficient or if there is only a narrow trickle being delivered, there might be a problem with the suction hose of the pump. Check the manual for the correct size of the suction hose needed for your pump model. Sometimes the size becomes longer than required and this interferes with the water flow. Make sure that there are no internal damages in the hose. Check the inside of the suction hose to see if the fabric lining has frayed off. Replacing the lining can solve the problem. Ensure that the valves are all tightened and all the pump parts are in proper position.

Tip 4: Wire Errors

At times, there might arise a problem due to errors in the wiring system or the pump components, right after it is installed. Sometimes an irritating buzz is heard as soon as the pump is switched on. This might be a fault in the installation of wires. Check your manual for the amplification readings meant for all the wires of different colors. Check if these are matching with the readings you take on an ohm meter. The maximum reading must be seen in case of the red to black wire connections and the lowest for yellow to black wire connections. In case of mismatched readings, the set has to be replaced. If the pump is straight out of the box and has not been tampered with, you can get a replacement free of cost, due to the warranty offer.

Tip 5: Control Box Faults

Check the control box of the electric water pump. Search for small black colored components that are cylindrical in shape. These are the start capacitators of the pump. See if the connectors between them are giving out an inky puss-like liquid. Check for any trips in the red overload relay. If the ohm meter gives a reading that is normal in terms of the manual after the relay has tripped, then you need to replace the components of the control box. However, if you see a bad reading on the start relay, the whole control box has to be removed and a new unit has to be set up.
