Quick Answer
Submersible pumps can be used with pressure tanks, but it's crucial to match the pump's output pressure to the tank's rating and the desired water pressure at the tap.
Choosing the Right Pump and Tank Combination
When pairing a submersible pump with a pressure tank, consider the pump’s flow rate, head pressure, and power requirements. For example, if you need 10 gallons per minute (GPM) at 50 feet head pressure, choose a submersible pump that can deliver at least this flow rate and pressure. A 20-gallon pressure tank with a 40-psi rating would be suitable for this application.
Pressure Tank Sizing for Submersible Pumps
Pressure tank sizing depends on the pump’s flow rate, the number of users, and the water pressure requirements. A general rule of thumb is to size the tank for 2-5 gallons per minute (GPM) of water usage per person. For a single-family home with four people, a 40-60 gallon pressure tank would be more than sufficient for a submersible pump delivering 10-15 GPM.
Installation and Maintenance Considerations
When installing a submersible pump with a pressure tank, ensure the tank is rated for the pump’s pressure and flow rate. Regularly inspect the tank and pump for signs of wear, corrosion, or leaks. Check the tank’s air charge and add air as necessary to maintain the recommended pressure. This will help extend the life of the tank and pump, and ensure reliable water supply.
