What maintenance tasks are essential for underground propane tanks?

Inspecting for Leaks and Corrosion

Inspect underground propane tanks for signs of leaks or corrosion at least once a year. Look for rust, holes, or discoloration on the tank’s surface and surrounding soil. Check the tank’s valve stems and gaskets for signs of wear or damage. Remove any soil or debris that may be covering the tank’s surface or connections. Use a soap solution or propane detection kit to test for leaks.

Checking Vent and Drain Lines

Verify that the tank’s vent and drain lines are properly connected and free of kinks or blockages. Check the vent line for any signs of ice formation or corrosion, which can cause gas to accumulate and lead to explosions. Ensure the drain line is sloped correctly to prevent water from accumulating and causing corrosion. Check the drain valve for any signs of wear or damage.

Ensuring Proper Soil Compaction

Verify that the soil around the tank is properly compacted to prevent settling or shifting. Check the tank’s position and ensure it’s level and plumb. Use a soil compactor or a tamper to compact the soil to a depth of at least 12 inches around the tank. This will help prevent the tank from shifting or settling, which can cause damage or leaks.
