Quick Answer
To troubleshoot low water flow from a developed spring, check the water level, inspect the spring box and screen, and measure the flow rate to determine if the issue lies with the spring itself or the piping and distribution system. Measure the water level in the spring box and compare it to the water level in the surrounding aquifer. Check for signs of sedimentation, clogging, or animal activity.
Inspect the Spring Box and Screen
Inspect the spring box and screen for any blockages or damage. Check for signs of sedimentation, silt, or debris accumulation. Clean or replace the screen if necessary. A 1/4 inch or smaller screen mesh is usually sufficient to filter out sediment and debris. If the screen is damaged or corroded, replace it with a durable, corrosion-resistant material like stainless steel or PVC.
Measure the Flow Rate
Measure the flow rate at the spring source and at various points downstream to determine where the flow is being restricted. Use a flow meter or a bucket to measure the flow rate in gallons per minute (GPM) or liters per minute (LPM). Compare the flow rate measurements to determine if the issue lies with the spring itself or the piping and distribution system. For example, if the flow rate at the spring source is 5 GPM but drops to 1 GPM at the distribution point, the issue likely lies with the piping or distribution system.
Check the Piping and Distribution System
Check the piping and distribution system for any blockages, kinks, or restrictions. Check for signs of corrosion, scaling, or sediment buildup. Clean or replace any damaged or corroded pipes or fittings. Use a pressure gauge to check the water pressure in the system. If the pressure is low, it may indicate a blockage or restriction in the piping or distribution system.
