摘要：
Exemplary embodiments include a unitary pool filter tank and/or an underdrain for a pool filter unit. Embodiments of the unitary pool filter tank can have an integrally formed housing and base. The filter tank can be formed using a blow molding process in which the base of the filter tank is reinforced using multiple polymer layers that have been folded and/or pinched together. Embodiments of the underdrain can be formed by interlocking top and bottom components. The top and bottom components can be interlocked by inter-component locking structures.
