If your well does not produce an adequate amount of water and you have to use a holding tank, then you need to know how to troubleshoot and repair problems with pressure tanks and their water pumps. Both water pumps and pressure tanks are prone to failure from natural contamination in water and overuse.
Follow this procedure to troubleshoot your well plumbing's pressure tank and water pump:
Is There Electricity Service to the Water Pump?
The water pump for your well system's pressure tank runs on electrical current. So, the first step in troubleshooting problems is to verify that the current is on at the power panel. If the power is on to the pump, but it still will not run, then you need to turn the power off for the next step in the troubleshooting process.
Is There Water and Air Pressure in the Pressure Tank?
Your pressure tank is designed to have a balance of air and water inside of it. The air and water are kept apart from each other via a rubber bladder inside of the pressure tank.
The first step in troubleshooting the pressure tank is to rock it gently back and forth to check to see if it has water inside of it. If the tank is void of water, then the rubber bladder inside of the tank has likely failed. Bladders cannot be repaired, and this problem requires replacement of the pressure tank itself.
If the tank is heavy with water, then you should check the pressure gauge to ensure that the tank is pressurized. If there is no air pressure in the tank, then connect an air compressor's hose to the tank and fill it with air up to the manufacturer's specifications.
If the gauge has pressure and the tank clearly has water, then the pressure switch may be the problem or the pump may have failed.
Is the Pressure Switch Tube Clogged?
The pressure switch that tells your water pump to turn on and off is located at the back of the water pump. Check the tubing that runs from your pump's inlet valve to the pressure switch. If this small piece of rubber tubing is clogged, then the switch will not activate the pump. Remove the tubing if you need to clean it, and blow it out using your air compressor.
Is the Water Pump's Impeller Broken?
Finally, if the pressure tank has air and water pressure, and there is power to the pump and no clog in the pressure switch tubing, then the impeller for the water pump is likely broken. If you have a metal pump, then the impeller can be replaced with a new one. If you have a plastic pump, then you will need to have the entire pump replaced.
