Absolute Tank Testing performs the Horner EZY3 Locator Plus non-volumetric tank test. This testing method has proven to be highly effective and most reliable on residential tanks. This testing method can provide results on the same day the test is conducted or within 24 hours of testing. This testing method can only be performed on tanks with a straight or direct fill pipes. This testing method would require access to the furnace therefore it may be necessary for the homeowner to be there. For underground gasoline and diesel tanks access to and shut down of the dispenser/pump will be required. As with all of our testing procedures a field screening of the soil for evidence of petroleum is included.
