Quick Answer
Low water output from a well may be caused by several factors, including a low water table, a clogged or damaged well screen, or a malfunctioning pump. To troubleshoot, check the well's water level and look for any signs of damage or blockages.
Checking the Water Level and Well Screen
Check the well’s water level by inserting a measuring tape or a rope with knots at regular intervals into the well. Record the depth to the water level and compare it to the well’s original depth. If the water level is significantly lower than expected, it may indicate a low water table or a problem with the well’s casing.
Pump and Equipment Inspection
Inspect the well pump, pipes, and fittings for any signs of damage, corrosion, or blockages. Check the pump’s suction and discharge pipes for kinks, blockages, or loose connections. Also, inspect the well casing and screen for any damage, clogs, or debris.
Testing and Maintenance
Test the well’s yield by measuring the water flow rate using a flow meter or a bucket. If the flow rate is low, try running the pump for an extended period to see if the water level rises. If the water level does not rise, it may indicate a problem with the well’s production. Perform routine maintenance on the pump and equipment, such as cleaning the pump and replacing worn-out parts. Consider having a professional inspect and repair the well if you are unsure about the cause of the low water output.
