Quick Answer
During a pressure tank installation, watch for proper tank size selection, correct piping connections, and adequate air charge volume to ensure optimal system performance.
Choosing the Right Tank Size
When selecting a pressure tank, it’s essential to consider the household’s water demand and the pumping system’s capacity. A general rule of thumb is to choose a tank with a minimum capacity of 20 gallons per 1,000 square feet of living space. For example, a 2,000-square-foot home would require a 40-gallon tank. Ensure the tank is also compatible with the pumping system’s pressure range and flow rate.
Piping Connections and Air Charge
Proper piping connections are critical to ensure the tank’s performance and longevity. Use ¾-inch or 1-inch pipe for the tank’s inlet and outlet connections, and ensure they are securely tightened with a wrench to prevent leaks. When charging the tank with air, use a pressure test gauge to add air in increments of 1-2 pounds per minute until the recommended pressure is reached (typically 2-5 pounds per square inch). This will prevent overcharging and ensure the tank’s diaphragm operates within its optimal range.
Final Inspection and Testing
Before completing the installation, inspect the tank’s connections, piping, and electrical components to ensure they meet local codes and regulations. Perform a hydrostatic test to check for leaks and ensure the tank can withstand water pressures. Finally, test the system’s functionality by checking the tank’s pressure gauges, flow rates, and overall performance to ensure a safe and reliable water supply.
