Abstract
A self-levelling supporting base for a tank. The base includes an annular skirt having an upper rim disposed in contact with the lower dome-shaped head of the tank. A curved wall is connected to the rim and extends across the skirt and is spaced beneath the head. The wall is provided with a central opening to receive a member, such as a fluid pipe, that is connected to the lower head. A washer surrounds the member and the lower end of the member is engaged with a connector, such as a fitting, which acts to deform the wall and urge the rim into tight engagement with the head of the tank. The opening in the curved wall is substantially larger in diameter than the member with the result that the base can be shifted laterally to properly align the tank on an uneven supporting surface. A flexible lip extends upwardly from the rim in engagement with the head and acts to provide a seal between the tank and the base as well as increasing the frictional resistance between the base and the tank to aid in maintaining the tank in proper alignment on the base.
