1000 gallonundermount propane tank

A 1000-gallon underground (undermounted) propane tank is a large-capacity storage unit designed to be buried beneath the ground, offering a low-profile solution for residential, commercial, or agricultural propane needs while maintaining curb appeal. These tanks are typically used for whole-home heating, powering multiple appliances (e.g., water heaters, generators, pool heaters, cooking appliances), or supporting commercial applications like restaurants, dry cleaning, or crop drying. Below is a detailed deion based on standardized specifications and common features from reliable sources. Key Specifications • Capacity: • Total water capacity: Approximately 1000 gallons (3785 liters). • Propane capacity: Holds 800–850 gallons when filled to 80–85% for safety, allowing room for gas expansion. • Dimensions: • Length: 15’11” to 16’ (187–192 inches). • Diameter/Width: 41 inches (3’5”). • Height: 4’9½” to 6’3/16” (including dome/lid for underground access). • Variations depend on manufacturer and dome design. • Weight: • Empty: 1760–2076 lbs (varies by manufacturer). • Full: Approximately 5048–5160 lbs (adding ~3288 lbs of propane at 4.11 lbs/gallon at 77°F). • Material: Corrosion-resistant steel, often coated with: • Red oxide durable powder coating or zinc-rich epoxy primer with a TGIC polyester topcoat for underground durability. • Black polyethylene shroud or green composite dome protects the lid, regulator, gauges, and filling port. • Pressure Rating: Rated at 250 psig from -20°F to 125°F, conforming to ASME Section VIII, Division 1, and NFPA 58 standards. • Vacuum: Pre-purged with a full 14.7 psi vacuum seal; first fill requires a propane provider to break the seal using methanol via the POL valve. Design and Features • Underground Installation: • Buried with only the dome/lid visible above ground, housing the regulator, gauges, and ACME fill valve for easy access while protecting components from weather. • Requires excavation, causing temporary yard disruption, but the area can be re-landscaped with grass or sod, potentially enhancing property value. • Surrounded by earth, it’s less affected by extreme temperatures or freezing compared to aboveground tanks. • Safety and Compliance: • Meets ASME and NFPA 58 standards for pressure vessels. • Includes a #72 liquid level outage valve and internal gauge for monitoring (refill recommended at 20–30% capacity). • Requires a twin-stage regulator for safe pressure management. • Odorant added to odorless propane for leak detection. • Installation Requirements: • Must be installed by certified technicians, with a minimum distance of 10 feet from buildings and property lines (per NFPA for underground tanks over 500 gallons). • Requires excavation and a stable base (e.g., solid cement blocks or gravel bed); no concrete slab needed, unlik
