What to do if my Goulds VJ10 delivers water but will not shut off?
If your Goulds Water Pump delivers water but doesn't shut off, it could be due to a plugged or incorrectly adjusted pressure switch. In this case, you should clean and adjust the pressure switch. Another potential cause is a defective suction check or foot valve, which would require replacement.
Why is my Goulds VJ10 Water Pump not running?
If your Goulds Water Pump isn't running, there are several potential reasons. First, the motor thermal protector may have tripped; try resetting it. Second, check for an open circuit breaker or a blown fuse and replace them if necessary. Finally, the motor itself might be defective, requiring replacement.
What to do if my Goulds VJ10 cycles excessively?
If your Goulds Water Pump cycles excessively, it could be due to a water-logged pressure tank. Try draining and recharging the pressure tank. Another cause might be the pump being farther than 5 feet from the tank; move the pump closer. High friction loss valves between the pump and tank may also be the reason; replace them with fully open gate valves to reduce friction loss.
How to fix little or no liquid delivered by Goulds VJ10 Water Pump?
If your Goulds Water Pump delivers little or no liquid, it could be due to several reasons. First, the pump might not be primed, the suction pipe submergence may be inadequate, or there could be an air leak in the suction pipe. Prime the pump and ensure the suction pipe is correctly submerged and free of leaks. Second, the discharge or suction may be plugged, or a valve may be closed; clear any blockages and ensure valves are open. Finally, the suction lift or suction losses may be excessive; reduce suction lift and minimize losses.
Ensure qualified technicians, adhere to codes, and disconnect power before electrical work to prevent shock or damage.
Avoid hazardous liquids, venting, over-pressurization, and protect tanks from moisture to prevent hazards.
Install adequate suction pipe, avoid filters, and throttle suction to prevent over pumping.
Install jet assembly with nozzle, venturi, foot valve, and tailpipe, setting it below static water level.
Soak packer leathers, install jet assembly with strainer and tailpipe, and push into well casing.
Install a pressure control valve or flow restrictor in the discharge line to ensure back pressure for jet assembly operation.
Use a separate branch circuit with a properly sized breaker or fuses, conforming to all codes.
Connect power supply wires to the pressure switch and ensure motor voltage matches incoming voltage.
Change motor voltage inside the motor cover, not the pressure switch, following wiring diagrams.
Steps for changing motor voltage using plugs on A.O. Smith/Century and Nidec motors.
Explanation of terminal board layouts and voltage plug connections for motor voltage changes.
Install vacuum gauge in shallow well adapter or pump to measure suction lift in inches of mercury (Hg.).
