To pump out an oil tank, particularly one containing heating oil, the process involves using a fuel transfer pump to remove the bulk of the oil, followed by strategically tilting the tank to collect and drain the remaining contents.
Step-by-Step Process for Draining an Oil Tank
Draining an oil tank requires careful execution to ensure most of the oil is removed efficiently. Based on established methods, here's a breakdown of the process:
- Initial Bulk Drainage: Begin by using a 12v fuel transfer pump to drain as much heating oil out of your tank as possible. This pump helps move the oil from the tank through a hose into suitable storage containers. Continue this step until the pump struggles to pick up the oil consistently.
- Reduce Weight: Once the tank is fairly empty and its weight has been greatly reduced by the initial pumping, you can proceed to the next step more easily.
- Elevate One End: To collect the remaining oil, elevate one end of the tank. This allows gravity to pool the residual oil at the opposite, lower end.
- Drain Remaining Oil: Continue to use the fuel transfer pump or another suitable method to drain the oil that has collected at the elevated end of the tank. Ensure this remaining oil is removed into drums or other appropriate storage vessels.
- Final Collection: Repeat the elevation and draining process if necessary, tilting the tank slightly in different directions if possible, to gather any last bits of oil. Continue draining until all of the heating oil has been removed into drums.
Tools and Supplies
To complete this task, you will typically need:
- 12v Fuel Transfer Pump: A pump specifically designed for fuel transfer.
- Hoses: Appropriate hoses for connecting the pump to the tank and the storage drums.
- Storage Drums: Suitable containers for holding the drained oil (ensure they are rated for fuel storage).
- Blocking/Supports: Materials to safely elevate the tank (e.g., sturdy blocks, jacks).
Note: Always ensure you are following local regulations regarding oil transfer and disposal.
