Used 500lbs of glass instead of sand and it filters great. Real good flow, quick backwash. Water is crystal clear Review: Love it! Hayward makes great sand filters! - I bought this large sand filter to replace the identical 8-year-old Hayward filter for my 44,000 gallon pool. The old filter had developed a 4" long crack near the top of the tank. i couldn't get it to stop leaking even with copious amounts of J-B WaterWeld applied inside and out. This filter arrived quickly and was very easy to set up. It's BIG, but I have lots of room in my pool equipment area with wide open access. Being exactly the same filter as the old one (minus the "2" at the end of the model number), all of the PVC piping back onto this filter's valve perfectly. I have PVC unions on the pump, return, and waste PVC piping so it's easy to disconnect and reconnect the valve. I used the recommended pipe sealant on the threaded connections to the filter valve. I simply cut up the old filter with vertical cuts I made with my reciprocating saw, so I could take it apart and easily shovel out all of the old sand in it... 500 lbs of it! it went quickly though. Then I set this new filter tank in place, put the valve on top, and connected the PVC lines to it to properly position it. Then I disconnected the lines, pulled the valve, put the standpipe in and positioned the laterals, taped off the top of the standpipe, and filled the tank half full with water. Time to add the sand. I used 250 lbs of Zeosand this time around, instead of 500 lbs of standard filter sand. My old sand needed to be replaced anyway, and I got 8 years out of it with no problems - much longer than the recommended 3-5 years. I used the little cardboard brace that came with the filter to hold the top of the standpipe in the center of the tank neck, and VERY CAREFULLY poured in the Zeosand cup by cup at first, keeping the standpipe centered and vertical. After 50 lbs of Zeosand was in, the standpipe and laterals were fixed in position and I could pour in the remaining 200 lbs of Zeosand more quickly. After that, I put the valve back on, lubricating the big O-ring with silicone pool lube, and reconnected the PVC piping. I also screwed my pressure gauge into the new valve using pipe sealant. The filter is working perfectly with the Zeosand, with no more leaks! I backwashed the filter with the Zeosand in it until the sight glass ran clear - about 3 minutes to get rid of the green color from the Zeosand - then rinsed for about 30 seconds, and finally put it in the filter position. The pool is sparkling clear. I can't ask for more than that! The valve lever on this new filter turns FAR easier than the old one did even when it was brand new in 2013. In fact, the lever turns so easily, at first I feared it was broken inside - but it works in each position. i guess Hayward has improved the internal workings on the valve to make it easier to turn. I'm fine with that. ## Features - BALANCED FLOW & BACKWASHING: The Hayward ProSeries 30.5-Inch Top-Mount Sand Pool Filter features an efficient, multilateral underdrain assembly with 360Β° self-cleaning slotted laterals and includes 2-inch filter valve - MAXIMUM FILTRATION: Integral top diffuser on the Hayward pool filter ensures even distribution of water over the entire sand bed for optimal use of filtration area - ALL-WEATHER PERFORMANCE: This Hayward sand filter features a unitized, corrosion-proof filter tank molded from rugged polymeric material, delivering dependable performance in any weather for outdoor pools - EASY OPERATION: This swimming pool filter features a 6-position Hayward VariFlo control valve with easy-to-use lever-action handle that lets you quickly dial in the right valve/filter function for low maintenance - RAPID WINTERIZING: Hayward sand pool filters have a large pressure sand/water drain that is always ready for quick winterizing or servicing ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07SPM17K6 | | Best Sellers Rank | #97,177 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #125 in Sand Pool Filters | | Brand | Hayward | | Brand Name | Hayward | | Color | Tan | | Customer Reviews | 4.5 out of 5 stars 47 Reviews | | Global Trade Identification Number | 00610377387804 | | Included Components | Sand filter | | Indoor Outdoor Usage | Outdoor | | Item Dimensions L x W x H | 30.5"L x 30.5"W x 48"H | | Item Type Name | Pool Filter | | Item Weight | 83 Pounds | | Manufacturer | Hayward | | Manufacturer Part Number | W3S310T2 | | Material | Sand | | Material Type | Sand | | Model Number | W3S310T2 | | Product Dimensions | 30.5"L x 30.5"W x 48"H | | Required Assembly | No | | Shape | Round | | UPC | 610377387804 | ## Product Details - **Brand:** Hayward - **Color:** Tan - **Included Components:** Sand filter - **Material:** Sand - **Shape:** Round ## Images ![W3S310T2 Pool Sand Filter, 30 Inch - Image 1](https://m.media-amazon.com/images/I/81qXUUV4cEL.jpg) ![W3S310T2 Pool Sand Filter, 30 Inch - Image 2](https://m.media-amazon.com/images/I/81Hhp3NjfZL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Will this size work for a 33,000 gallon pool?** A: Yes it will. **Q: How many pounds of sand ?** A: 600 lbs **Q: I have a 33’ above ground. What size do I need?** A: We have a 31’ ft pool and this one works well. We’ve used it one season. **Q: Will this work for a 55000 gal pool?** A: Yes it will work for 55,000 gallons. However, you will have to backwash it a lot more frequently than if you get a 600 lb filter instead. Another factor would be your pump size, if you have a larger than 2HP motor, then the larger size would definitely be better. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very nice! *by W***D on April 21, 2026* Very satisfied.
