Quick Answer
Yes, you can install a pressure tank outside your home, but it's essential to follow local building codes and ensure proper installation to prevent freezing and water damage.
Choosing a Location for Your Pressure Tank
When selecting a location for your pressure tank, consider the following factors: distance from the water source, accessibility for maintenance, and protection from extreme temperatures. Typically, a pressure tank should be installed at least 12 inches off the ground to prevent freezing and water damage. If you live in an area with freezing temperatures, consider installing the tank in a frost-protected location, such as a basement or an insulated shed.
Sizing Your Pressure Tank for Proper Performance
To determine the correct size of your pressure tank, calculate the total water demand of your household in gallons per minute (GPM) and match it with the correct pressure tank size. A general rule of thumb is to size the tank for 2-5 gallons per minute of water usage. For example, if your household uses 3 GPM, a 20-gallon pressure tank would provide adequate pressure and water supply.
Additional Considerations for Outdoor Installation
If you decide to install the pressure tank outside your home, ensure it’s properly protected from the elements. Apply a rust-inhibiting coating to the tank and consider adding a roof overhang or installing a canopy to shield it from direct sunlight and precipitation. Additionally, ensure the tank is securely fastened to the ground to prevent it from becoming dislodged during strong winds or seismic events.
