Filter Grids, DME

[PoolDoc]

The ones with the fewest broken ribs and tears were the original Pentair grids.

------------------------------

I would like to know which brand of grids besides Pentair is of good quality?

Aftermarket plastic -- grids, gaskets, etc. -- has NEVER been "of good quality" in my experience. The one exception has been O-rings, which I buy from an industrial O-ring house, and get them cheaper and better. But, that's not a practical option for individual pool owners.

So . . . get the OEM if you can.

Failing that, Unicel has a pretty good reputation -- this appears to be the correct set (check carefully!) on Amazon:
Unicel FS-2005 Replacement Filter Grid for American, Hayward, Pac-fab 7 Full + 1 Partial Set @ Amazon

(Waste & I were posting at the same time -- it's interesting that he recommended the Unicel -- and also that when I posted the link the price was considerably less than what he mentioned.)

You can call these people:
http://www.a1poolparts.com/-strse-65...ter/Detail.bok
but, ask whether they are selling Pentair OEM -- if not, stick with the Unicel. If they are, they have a better price.

And of course, you can search around on the Internet. There are two problems however. Ordering parts, you need EITHER a complete set (like Amazon) OR to order from a supply house where the people are knowledgeable. I've personally ordered from A1 (they had some stuff cheaper than I could buy it 'wholesale'!), and the people I spoke with were knowledgeable. But there are LOT of Internet sites that are sales only, and seem to farm out the actual order fulfillment to other companies.

The other problem is, a lot of sites play games with names. For example, on A1's site, "Pentair replacement parts" does NOT necessarily mean "Pentair replacement parts" made by Pentair!. So be careful. Even some of the "Unicel" cartridges sold on Amazon are actually Pleatco (not desirable), and you have to read VERY carefully to work that out.

Here's the manual, I believe:
