Claim:
A tank for holding liquid and having an internal baffle comprising: a main body including a main body bottom wall and a side wall connected together forming an internal tank cavity for holding liquid; a baffle wall extending within said cavity and being secured to said main body only at a location above said liquid, said baffle wall having a top end secured to said side wall at said location above said liquid and an enlarged flared bottom portion resting atop said bottom wall to limit sideways movement of said baffle wall atop said bottom wall, said baffle wall divides said cavity into multiple compartments between said baffle wall and said side wall; and, a holding support secured to said side wall and said top end of said baffle wall limiting sideways movement of said top end relative to said side wall; and wherein: said enlarged flared bottom portion includes a pair of outwardly diverging walls and a bottom baffle wall joined together forming a hollow interior with passages extending from said multiple compartments into the hollow interior of said baffle wall to allow liquid within said multiple compartments of said tank to flow into said hollow interior as contrasted to moving between said multiple compartments increasing the weight and stability of said baffle wall by limiting movement between said bottom baffle wall and said main body bottom wall, said holding support is a downwardly opening channel loosely receiving said top end of said baffle wall allowing limited movement of said baffle wall relative to said holding support, said flared bottom portion has a pair of end walls joined to said diverging walls and said bottom baffle wall forming said hollow interior, said end walls are spaced apart from said side wall of said main body being unconnected to both said main body bottom wall and said side wall at said flared bottom portion, at least one of said end walls has a hole extending therethough so liquid within said compartments of said main body may flow between at least one of said end walls and said side wall and through said hole into said hollow interior limiting movement of said baffle wall relative to said side wall.
