Pleatco PFS1836 Cartridge/Grid Replacement for American, Hayward, Pac-Fab 7 Full and 1 Half/Universal Grid Set

My filter grids developed tears after 8 years of use and I needed to buy new grids. Leslie's wanted $447 for the exact same manufacturer and model number grids as these and were sold out for at least 14 days. I ordered these and they arrived in 3 days with prime and fit perfectly. The water showed immediate improvement for clarity after the initial 10# DE load. I then vacuumed up the excess filter media from my pool bottom and within 30minutes the pools was nearly crystal clear. Will respond back on durability after the summer season. I rated the ease of install solely on the fact these grids fit perfectly in the filter housing - putting the filter back together is always a little challenging...lol Definitely worth the money especially at 1/3 the price of your local pool store!

Just installed these today in a Pentair FNS 36sqft filter. The old ones were 6 years old and one of the grids had developed a few tears that were allowing the DE to flow back into the pool. Last year I had disassembled the filter and cleaned the grids and didn't notice the hole. I never seemed to get the flow through the old grids that I was expecting. Well I discovered today the reason why was because the grids were caked with calcium deposits which restrict water flow. Anyway, these inexpensive grids are working great, actually too good as I had to reprogram my multi speed pump to prime at a lower speed because the flow was now so high that the fountains looked more like a volcano exploding. I might grab another set at this price and put them in the shed. I figure if they last 3 years they will still be 1/3rd the price of the Pentair grids yet last half as long... so they're a good deal.

This set was affordable and arrived quickly. Just as advertised. The fins fit nicely into the pool pump and they worked with zero issues. Very happy with the purchase.

The grids work great but the inside fins are slightly too fragile for long term use. This is my 3rd set in two years. I had hoped to get at least two years out of each set.

I only gave 4 stars for value and durability only because when purchased everything on the planet is overpriced and I won’t know how durable they really are until after a few seasons. What I can say is they seem to be better made than the original Hayward grids. These have a double stitch sealing the bottom of the grid whereas the original Hayward grids have a single stitch and the rest of the seam was glued which is why mine failed after only 2 seasons shame on Hayward for charging top dollar for inferior product.
