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.

In combination, a tank having a dome-shaped lower head, a member extending axially outward from said head, a base secured to said head and disposed to support the tank from a supporting surface, said base comprising a generally annular skirt having an upper rim disposed in contact with said head and having a lower edge resting on said supporting surface, a wall extending across said skirt and spaced beneath said head and having an opening to receive said member, the area of said opening being substantially greater than the area of said member whereby said base can be shifted laterally relative to said member, and connecting means connected to the lower end of said member and disposed in contact with the lower surface of said wall to cause said rim to be brought into firm engagement with said head, lateral shifting of said base relative to said head enabling said base to conform to uneven supporting surfaces.
