Abstract: An improved filter capable of operating in a backwash mode that creates an upward swirling flow in the hollow interior of the pool filter container. During the backwash cycle, water or air and water are injected into the pool filter container at an angle. In the preferred embodiment, a mixture of water and air are injected into the filter container through exit jets located within the hollow interior of the filter container proximate to the bottom of the filter container. This causes the filter media to swirl upward mixing thoroughly with the backwash water promoting the separation of the mineral deposits from the filter media.

Abstract: A method for sealing or resealing a masonry surface in a swimming pool. In a new pool, spa, or similar structure, the masonry surface is cleaned and prepped. A diluted mixture of silicone sealant is then applied to the surface. Staining dyes are optionally added to the sealing formulation. In the case of an old pool, voids and cracks are sealed with a filler. The diluted mixture of silicone sealant is then applied over the old plaster and the filler materials to reseal the surface. Staining dyes may be optionally added to this application of the inventive method as well. A second formulation of the sealant can be used to affix and grout tiles in order to seal all or part of a pool's wall surface.
