Review: Perfect Fit, Easy installation, High Quality - 1) Quick delivery 2) No damage 3) Easy installation 4) Perfect replacement fit for old Hayward filter 5) Out of box ready to install, took 15 min 6) Came with full complement of filter elements 7) Plug and play to existing Hayward backwash valve 8) Price was higher than knock off, but worth every penny Review: Just installed - Easy Peasy - Replaced my 30 year old Hayward DE filter (worn out grids, time to replace the entire system). Remove replace in 45 minutes. Simply attached it to my Hayward backflush valve, even used same O-rings but with fresh lube. Loaded it with DE and has a working pressure of about 5lbs @ 1750 RPM on the Hayward variable pump. Primed it at 2500RPM about 6 times to check for leaks at higher pressure and nothing. Will update after first backflush come late Spring. Shout out to reviewer who pointed out that cannister filter has reverse i/o ports. Initially wanted cannister but changed my mind later. Would have been really pissed if purchased cannister to then discover I would need to reverse my plumbing. Dodged a hefty and totally un-needed bullet there! And glad didn't have to deal with Hayward customer service because they are worthless (non-existent). Oh, and did come with Hayward OEM grids installed. ## Features - The Hayward ProGrid 48-Square-Foot Pool Filter offers superior large-capacity performance, efficiency and water clarity - High-impact grid elements provide up-flow filtration and top-down backwashing for maximum efficiency - Durable, glass-reinforced copolymer construction ensures corrosion-free durability and withstand the elements - Heavy-duty, tamper-proof, one-piece clamp provides quick access to internal components without disturbing plumbing connections - High-capacity, rapid-release manual air relief valve bleeds air with a quick quarter turn of the lever ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07SS48CBC | | Best Sellers Rank | #290,951 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #74 in Pool DE Filters | | Customer Reviews | 4.2 4.2 out of 5 stars (138) | | Item Weight | 73.8 pounds | | Item model number | W3DE4820 | | Manufacturer | Hayward | | Product Dimensions | 23.1 x 24.6 x 41.8 inches | ## Images ![W3DE4820 ProGrid Diatomaceous Earth DE Pool Filter for In-Ground Pools, 48 Sq.
