OVERVIEW
Pool Supply Unlimited offers high quality grids at a great price. Have a question about which grids you need for your specific filter? Give us a call, we're open 7 days a week.
Our grids feature 100% polyproplene cloth which uses a higher denier and different weave patterns than most grids on the market. This allows for better control of the fabrics permeability. Polypropylene is also rot and mildew resistant and has excellent resistance to alkalis and acids. When compared by an OEM manufacture, our grids had better dirt holding characteristics and lower pressure drop than the competition.
Some common features which you will notice:
Stronger and more durable internal frames which holds the polypropylene fabric
100% Polypropylene cloth finished to exact standards assures precise control of filtration efficiency, dirt holding and D.E. cake release.
Fewer glue joints together with re-enforced spines increase the torisional strength and prevents snapping of the grids
We offer grids as a complete set which includes 7 full size grids and 1 partial grid or they are also available for individual purchase.
BEST ANSWER:These are perfect filters. I have ordered twice over the years and have always been very happy with them, they are durable, last well and the pool looks great.

What causes grids to collapse? I bought a full set of these and they worked great for about a year but now some are getting flat spots. Now the filter is not removing algae. Is there something else I need to fix before putting in new grids? How long should they last? I was back washing as soon as the pressure climbed 20 above the clean level.
BEST ANSWER:The only reason that the grids may collapse is that you have not had your water at optimal chemical balance or you haven't cleaned them as often as you should. That is the key to maintaining the entire system not just the grids. I've been able to keep my grids healthy by cleaning them when I see water pressure drop from the spa overflow to the pool and after there has been a lot of debris generally. So it's a number of things. Basically keep the overall system well maintained with good chemical balance, check with your local retailer if you are doing it yourself to verify your results and they will last longer. Hopefully then you'll get more than a year or two out of them.
Thank you Coleman. We do have lots of tree debris and keeping the pool in balance is a challenge even for the pros. Guess I have to order a new set and try to do better.

The grids get crushed from the pressure rising too high. 20lbs above clean is way too high. Just backwashing does not sufficiently clean these grids plus when you backwash, you need to add more DE. My guess is that you don’t have enough DE on the grids so the pressure is rising quicker than normal and the grids are getting crushed as a result.
In my case I installed a grid filter without knowing my filter plumbing was for a DE filter and as a result I kept blowing grids apart. I went back to the original DE filter and now everything is running and cleaning the pool perfectly. I was dumb and it cost me for trying to switch.
20 PSI above the clean level is too high to wait to backwash, you should be backwashing when the pressure is 10 PSI higher then the clean level. That is why your grids did not last. Also you should be soaking the grids after each season and cleaning them for the next year.
He Lewis. I double checked my air relief valve and I was mistaken. I have been backwashin with a 10 psi increase and I also clean the grids at least 2 per year. Any idea why these grids are collapsing on me?
Can these filter grids be used in a Jandy Zodiac DEV48 pool filter? Complete Grid Set for 48 Sq Ft Filters | 24" Tall Grids | 7 Full, 1 Partial Top Manifold Style | FC-9540
I had a couple grids that leaked DE back into the pool and by replacing all of them at took care of the leaks and works great. It is cheaper to buy the whole set then to buy them individually and once Wen starts to leak the others aren’t far behind
My experience with Pool Supply Unlimited was great! The complete set of filter grids arrived quickly. Their service, cost & quality of product were all excellent! My pool water now sparkles and is absolutely crystal clear!
Couldn't ask for a better price and in no time I had my order. Friendly staff that are quick and knowledgeable. Will highly recommend Pool Supply Unlimited to all my friends and family. Thank you guys!
Price and time to deliver were excellent. The kit was supposed to have 7 full size grids and 1 partial but what came was 6 full size and 2 partial. Luckily I could use one of the old grids to complete the install. Otherwise, everything was great.
