The most direct way to determine the size of your underground oil tank is by checking its nameplate. This small plaque, often made of metal, is affixed to the tank and contains crucial information, including its capacity.
Locating Your Tank's Capacity on the Nameplate
According to industry standards, "You can find the capacity of your oil tank on its nameplate." This nameplate serves as the primary source for specifications, including the manufacturer, model number, and, most importantly, the tank's exact volume in gallons. For underground tanks, the nameplate might be located on an accessible part of the tank, such as near the fill pipe or vent pipe, often within the access pit or opening.
Understanding Common Oil Tank Sizes
While above-ground tanks often have capacities tailored for residential use, underground tanks typically cater to larger demands. Knowing the general size ranges can help you anticipate what to look for:
| Tank Type | Common Residential Sizes (Gallons) | Notes |
|---|---|---|
| Above-Ground | 275, 330, 500 | 275 gallons is the most common residential size. |
| Underground | 1,000+ | Underground tanks can be 1,000 gallons or more, suitable for larger properties or extended periods between refills. |
Why Knowing Your Tank Size Matters
Accurately knowing your underground oil tank's capacity is vital for several reasons:
- Efficient Fuel Ordering: It ensures you order the correct amount of fuel, preventing overfilling or under-delivery.
- Budgeting: Helps in forecasting fuel expenses based on consumption and tank volume.
- Maintenance & Compliance: Essential for scheduling inspections, repairs, and ensuring adherence to local environmental regulations, which often depend on tank size.
- Property Value: Accurate tank information is crucial during property sales and can impact insurance policies.
Other Methods to Determine Tank Size
If the nameplate is inaccessible or unreadable, consider these alternative methods:
- Review Home Inspection Reports: Previous home inspection reports or property records often include details about the oil tank.
- Check Building Permits: Construction or installation permits for the tank, typically filed with your local municipality, should list the tank's specifications.
- Contact Your Oil Delivery Company: Your current or previous oil delivery company might have records of your tank's size based on past deliveries.
- Consult Previous Owners: They may have documentation or knowledge regarding the tank's capacity.
By utilizing these methods, particularly starting with the tank's nameplate, you can accurately determine the size of your underground oil tank.
