Time to Replace Your DE Grids?
Our DE Grids are used on the most common pool filters including American Products®, Pentair®, Hayward® & Pac-Fab®. Most DE Filters will require 7 Full Grids and 1 Partial Grid. Typically DE grids last about 5 years so if it has been longer than 5 years then now is the time to replace your DE grids.
Things to Consider When Replacing Your DE Grids
Note: Collar has open slot (2 notches). Length is measured from one end of the grid to the other (collar not included).

How do I know which replacement grids I should order?

Typically, the filter label will contain the filter model and square footage of your grids. If the information on the label can not be read, you can measure the length (top to bottom) of the grid and multiply by 2 to get the square footage. For example: A 12" grid length would mean that the square footage is 24.

First turn off the pump. Then turn the relief valve located on the top of the DE canister. Then remove the drain plug on the back, bottom of the DE canister. From there, I removed the metal retainer ring that holds the top and bottom shells of my Hayward DE filter. I then removed the top shell, and the entire grid system by lifting on the two points of the manifold that have "life here" printed on it. After removing the entire grid system, I unscrewed the long threaded rod that holds everything together. I carefully placed the grid system up side down and removed each grid. I then replaced each grid making note of the one short grid so as not to place it in the wrong hold. After replacing all 8 grids (one short and seven regular size), I replaced the bottom piece and made sure the grids matched up to the grooves. After ensuring all grids were properly installed and in the correct grooves both on the manifold and the bottom piece, I replaced the threaded rod and with the washer and nut tightened snugly. Do not over tighten the nut. I then carefully placed the entire grid system back into the bottom shell making sure I lined up the PVC pipes. I placed the lid back on, then the retainer ring. Be sure to tighten the retainer ring until the springs touch. Close the relief valve and replace the drain plug. Turn on the pump and add the amount of DE to your skimmer basket port after removing the skimmer. Follow the instructions on how much to add and how to add it.

This is the same procedure for installing the other 7 grids, I'm repeating it here for completeness.
After opening the air relief valve to remove the pressure from the tank, I removed the tank cover. Then I took the grid assembly out of the tank. I disassembled the unit by removing the 5/16" locking nut from the top while holding the 7/16" nut at the bottom with an adjustable wrench. After disposing the old grids and hosing down the residual de from the other parts, with the aid of a video from YouTube, I reassembled the grids in the upright position using a grid guide costing $15 from a local retail store that really made it easy to attach the manifold. Reinstall the locking nut and place the complete grid assembly back into the tank. The whole process was fairly straight forward but took some patience. Most important thing is to replace each grid in the proper order. Total time spent about two hours.

Actually purchased the entire set of grids - found that 5 of the old grids were also torn/leaking the DE on the bottoms so now I have a spare grid. lineThey work like a charm-re-charged the filter with DE and they are filtering just fine-no leaking of DE back in the pool (that was the first sign that I needed new ones-nothing like adding DE and seeing it come roaring out of the return lines
