Quick Answer
Check for leaks in a jet pump installation by inspecting connections, checking for water flow at the pump's discharge, and testing the system under pressure to locate the source of any leaks.
Inspecting Connections
Check all connections between the jet pump, pipes, and fittings for signs of leakage. Inspect threads and pipe threads for any signs of damage or wear. Use a pipe wrench to tighten connections if necessary. Typically, check connections after 10-15 minutes of operation to account for temporary settling.
Testing the System Under Pressure
Use a pressure test gauge to test the system under 20-40 psi, depending on the jet pump’s specifications. Start by increasing pressure slowly and inspect the system for leaks. Use dye or a pressure test kit to pinpoint the source of any leaks. If you notice a leak, mark the location and turn off the system before further inspection.
Measuring Water Flow
Measure the water flow at the pump’s discharge using a flow meter or a bucket and a stopwatch. Compare the flow rate to the pump’s rated capacity to identify any potential issues. If the flow rate is lower than expected, inspect the system for clogs or blockages, and check for leaks.
