Quick Answer
Troubleshooting low water output from a deep well involves checking the pump's voltage, monitoring the well's static level, and inspecting the pump's impeller and casing for blockages. A faulty voltage supply or a clogged impeller can drastically reduce water output. It is also essential to ensure the submersible pump is properly sized for the well.
Checking the Voltage Supply
To troubleshoot low water output, start by checking the voltage supply to the submersible pump. The recommended voltage for most deep well pumps is 230-240VAC. Use a multimeter to measure the voltage at the pump, and compare it to the specified voltage. If the measured voltage is lower than the specified voltage, ensure that the electrical connections are secure and that there is no voltage drop due to long cable runs. A voltage drop can be prevented by using a larger gauge cable.
Monitoring the Well’s Static Level
The well’s static level can also impact water output. If the static level is low, the pump may struggle to draw water from the well. To monitor the static level, use a well casing gauge or a dip stick to measure the water level in the well. If the static level is consistently low, it may be necessary to install a more powerful pump or to modify the well casing to increase the well’s yield.
Inspecting the Pump’s Impeller and Casing
A clogged impeller or casing can also reduce water output. Inspect the pump’s impeller and casing for signs of blockages, such as debris or sediment buildup. Use a garden hose or a high-pressure washer to clean the impeller and casing, and check for any blockages that may be restricting water flow. It is also essential to ensure that the pump’s casing is properly sized for the well, and that there are no restrictions in the pipe system that can reduce water output.
