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 than 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).
I have a Nautilus NS-36 DE filter, (filter area 36 sq ft), that I need to replace the grids in. The full size grids measure approx.18.5 in length and are approx.19.5 wide. I need to replace the grids only, which ones should I be ordering? (the measurements don't seem to match up with the ones available for ordering)
I also get some DE reentering the pool from the returns which is creating a film on the bottom of the pool. What can I do to prevent this? Thank you!

Yes these actually would be the correct replacement grids or you can view the parts by clicking here to view key 10 for another option. You may also need to replace the manifold, the spider gasket in the multiport if you have one, or the o ring on key 12. We recommend inspecting those as well as for those can cause d.e. to go back into the pool.

I have a de filter attached to a pentair challenger cf series pump. The label says nautilus and serial # 0987-1104. All other information on the label has faded away. Can you tell me what model I have? I also sent an email yesterday to your company and haven't received any response.

The Nautilus series does have a few different models and we cannot use serial numbers for that series however Pentair can. Their phone number is 1-800-831-7133.

Because your tank appears to be stainless steel, there are two options: Pentair Nautilus Plus Stainless D.E. NSP36, 48, 60 & 72 or Pac Fab Nautilus Stainless D.E. If you cannot tell which model you have by the parts diagrams, then call Pentair with the serial number and they may be able to identify it.

Hi, This 36 Sq. Ft. Full Grid - FG1003 is the correct size grid for the Aquatic Systems FNS-36 filter. If you need to replace all of the grids only I would recommend p/n FG1003PACK or the complete grid assembly p/n 59023500.

Re: Hayward DE3620 Pro-Grid
Why is it cheaper to buy (7) Full Grid #FG1003 @ $19.99 + (1) Partial Grid #PG1903 @ $14.99 than it is to buy the Complete Grid Cluster #4810-65 @ $322.99? Thank you...
Reply
Hi David, the complete grid cluster includes other items besides the grids like the top manifold, bottom grid locator, retainer rod and stand pipe. These additional parts make the grid cluster more expensive then just purchasing the grids.

I need to replace all elements in my Pro-Grid Hayward DE 3620 filter. Which part should I order?
Reply
You can purchase the complete grid pack being part number FG1003PACK or you can purchase the complete rebuild grid assembly being part number 4810-65.The pack is just the elements and the assembly is ready to place back into the filter body already assembled.

Hi Cam, If you're purchasing p/n FG1003, you would only get 1 single grid. If want to replace all the grids then you will need to get p/n FG1006PACK.

I need to order replacement grids for my d.e filter but I'm not sure which ones to order. How do I know which one is the right one?

The easiest way to figure out the correct grid would be to measure the length and width and compare it to the measurements we have listed on the product page.

I went to a local pool supply store to order new grids for my pool filter. They told me they would have to oder them. The price they quoted me was twice the price that INYOPOOLs price was. Naturally I ordered from you guys and got delivery within 4 days. The product was perfect and saved 1/2! Very pleased.
