We recommend 500-Gallon tanks for most homes and small businesses. It holds enough propane to heat your average home for an entire season, but is compact enough to easily conceal above or underground.
Still deciding if a 500-Gallon propane tank is the right size for you? Here are some key characteristics to help you make your choice.
This tank’s moderate size offers an ideal balance between capacity and convenience. Our standard above-ground 500-Gallon propane tank measures approximately:
An empty 500-Gallon tank weighs about 950-1,150 pounds. When filled to maximum capacity, it holds around 1,520 pounds of propane bringing the total weight to 2,470-2,670 pounds.
It’s important to note that tanks are filled to 80% capacity for safety reasons, meaning they actually hold about 400 gallons. Given the weight, professional installation and solid surface reinforcement are required.
We recommend customers schedule a refill when the gauge reads 20-30% to maintain uninterrupted service.
A 500-Gallon propane tank maintains internal pressure of approximately 125-175 psi at average temperatures (60-70°F).
The pressure in a propane tank will naturally fluctuate - increasing during hot weather (200+ psi on very hot days) and decreasing during cold weather (below 100 psi in freezing conditions).
All our tanks have pressure relief valves that activate if pressure exceeds safe limits.
A 500-Gallon tank must be installed at least 10 feet from any buildings, property lines, and ignition sources to comply with NFPA 58 safety standards.
Above-ground tanks require a solid level surface like a concrete pad, while underground tank installation involves excavation and backfilling.
Professional installation is mandatory to ensure proper pressure testing, leak checking and connection.
You can check the propane level in your 500-Gallon tank by reading the built-in gauge, typically located under the dome lid.
The gauge on a full tank will show that it’s 80% full. When the level drops below 40%, it’s time to schedule a refill.
To request refills automatically, Pinnacle offers telemetry monitoring that tracks propane levels remotely and schedules propane delivery when needed.

500-Gallon propane tanks do not expire in the traditional sense, but they do require periodic inspection and recertification to meet safety and compliance requirements.
Recertification is usually required in intervals of 5 to 12 years, depending on local regulations and the type of tank. With regular maintenance and inspection, 500-Gallon propane tanks can last 30 years or more.

Refill your 500-Gallon propane tank when the gauge reads 20-30% to prevent running out, especially in winter or during high usage.
Since tanks are filled to 80% capacity, requesting a refill when the propane level drops below 40% guarantees enough time to schedule delivery. Pinnacle Propane customers can order their propane delivery online or sign up for our automatic refill service.
The decision to rent or buy your propane tank depends on your situation and unique needs.
Buying requires a large initial investment and full ownership of maintenance, but provides flexibility and long-term cost savings.
Renting with a supplier like Pinnacle Propane keeps initial expenses low and comes with maintenance and repair service, making it a more convenient option for many customers.

Deciding to install your tank above or underground depends on your budget, property layout, and aesthetic preferences.
Above-ground tanks cost less to install and are easier to refill and maintain. However they remain visible and exposed elements.
Underground tanks are hidden out of sight and less affected by weather, but require excavation and higher upkeep costs.
