Hello Rick, REPLACE GRID ASSEMBLY - The easiest way to replace all of the filter grids is to replace the whole grid assembly with a new one. This is also the most costly approach. For detailed instruction on replacing the grid assembly, follow the same instructions provided in our guide "How To Clean a Hayward DE Filter Grid Assembly". except instead of cleaning the grid assembly, replace the old grid assembly with a new one.VIEW TORN SEAM - This is an example of what a torn grid seam looks like. This type of damage occurs when the filter is under too much pressure for an extended period of time or the filter grids are old.VIEW BROKEN CORE - Sometime the inner plastic core breaks down and punctures the fabric of the grid. This can happen with age or if the grid assembly is not set correctly and is crushed when the tank top is set back in place.
