With a compact 19″ diameter tank and an effective filtration area of 1.8 sq ft, this model manages efficient turnover while requiring only 150 lbs of sand. Constructed with a one-piece thermoplastic tank for superior chemical and environmental resistance, it encapsulates a specially designed internal lateral system to maintain a flat sand bed and promote consistent flow and clarity. The top-mounted multiport valve centralizes operation and simplifies switching between key modes, while the combined drain further eases maintenance. Choose the SD40 when you need reliable performance in a smaller form factor without compromising on longevity.\u003c\/p\u003e\n\u003ch3\u003ePro Tip\u003c\/h3\u003e\n\u003cp\u003eKeep your pump’s flow rate under the ~40 GPM design rating to extend media life and backwash intervals. Confirm you have around 37″ of clearance above the filter for the valve and servicing. Load exactly 150 lbs of #20 silica sand for optimal performance and follow Pentair’s instructions for backwashing and winterizing.\u003c\/p\u003e\n\u003ch3\u003eInstallation Tips\u003c\/h3\u003e\n\u003cp\u003eHigh-level safety\/compatibility notes only: Before installing, shut off the filtration system power. Ensure the base is level and rated for the filter tank plus sand weight. Use #20 silica sand and load exactly 150 lbs per the manufacturer's instructions. Verify the multiport valve port size matches your plumbing (typically 1½″), and bond the metal components as required by local code. Do not exceed 50 psi operating pressure and follow Pentair’s manual for winterizing and servicing.\u003c\/p\u003e","brand":"Cavanaugh Pool, Spa \u0026 Patio, Inc.","offers":[{"title":"Default Title","offer_id":62589890724211,"sku":"PAC-05-0080","price":829.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0983\/2464\/4211\/files\/SandDollar_51445ee0-145d-46d3-ba10-940ca00c2c19.png?v=1772563810","url":"https:\/\/shop.cavanaughpool.com\/products\/pentair-sand-dollar-top-mount-filter-sd40-ec-145320","provider":"Cavanaugh Pool, Spa \u0026 Patio, Inc.","version":"1.0","type":"link"}
