Can underground tanks be refilled without excavation?

Refilling Underground Propane Tanks

Refilling underground propane tanks without excavation is possible using a technique called “refill through the tank’s manway” or “topping up”. This method requires a special riser assembly that connects the propane delivery hose to the manway, allowing the refill process to take place without exposing the tank or its contents. The riser assembly is specifically designed for this purpose and typically includes a valve, a hose, and a fitting.

Safety Considerations

When refilling an underground propane tank, safety must be the top priority. This includes ensuring the tank is properly vented, turning off the propane supply to the tank, and verifying the tank’s contents are at a safe level to prevent overfilling. Additionally, the area around the tank should be clear of any ignition sources and the refill process should be conducted in a well-ventilated area. It’s also essential to follow the manufacturer’s guidelines for the specific tank and refill system.

Equipment and Preparation

Refilling an underground propane tank without excavation typically requires a few specialized pieces of equipment, including a refill riser assembly, a propane delivery hose, and a tank lid adapter. The refill riser assembly should be designed for the specific tank size and type, and the propane delivery hose should be rated for the propane flow rate and pressure. Before the refill process begins, it’s essential to ensure the tank is properly secured and the surrounding area is clear of any obstructions.
