Tank Tightness Testers

The State of Tennessee does not currently certify proficiency of any tank tightness tester, nor does it endorse any particular methodology. In order to be valid, a test must be capable of detecting a 0.1 gallon per hour leak rate from any portion of the tank that routinely contains product while accounting for the effects of thermal expansion or contraction of the product, vapor pockets, tank deformation, evaporation or condensation and the location of the water table. The customer must satisfy him/herself that tank tightness testers are capable of conducting valid tests. You should also realize that a tank that passes a tank tightness test can still be losing product and if this results in an environmental problem, it will have to be cleaned up.
