Rated to 150 PSIG working pressure, the tank is built around a deep drawn steel shell with multi-dome construction and a heavy-duty butyl diaphragm that separates the air charge from the water supply. The antimicrobial liner neutralizes bacteria on contact, and the patented Turbulator water circulation device keeps water moving to prevent stagnation. The space-saver footprint makes it practical for installations where floor space is limited.\u003c\/p\u003e\u003cp\u003eThis tank is suited for residential well water systems where a compact vertical tank is needed in a utility room, crawlspace, or equipment area. The 20-gallon drawdown capacity supports standard single-phase submersible and jet pump configurations. The stainless steel system connection and welded air stem reduce corrosion and leak points at critical fittings. A patented DuraBase composite stand eliminates the corrosion common to steel base designs, making this tank appropriate for both indoor and outdoor installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e150 PSIG maximum working pressure with deep drawn steel and multi-dome shell construction\u003c\/li\u003e\n\u003cli\u003eHeavy-duty butyl diaphragm isolates air charge from potable water supply\u003c\/li\u003e\n\u003cli\u003eAntimicrobial liner neutralizes bacteria on contact for cleaner system operation\u003c\/li\u003e\n\u003cli\u003ePatented Turbulator water circulation device reduces stagnation inside the tank\u003c\/li\u003e\n\u003cli\u003eStainless steel system connection and welded air stem minimize corrosion and leak risk\u003c\/li\u003e\n\u003cli\u003ePatented DuraBase composite stand resists corrosion for indoor and outdoor use\u003c\/li\u003e\n\u003cli\u003eTuf-Kote HG exterior coating provides durable protection in demanding environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style pre-pressurized replacement or new-installation well pressure tank for residential and light commercial well water systems using standard submersible or jet pump configurations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eWell pressure tanks are typically installed by licensed plumbers in accordance with local plumbing codes and IPC guidelines. Before servicing or replacing an existing tank, shut off the pump breaker, relieve system pressure at a nearby fixture, and verify the pre-charge air pressure matches the system cut-in pressure before connecting. Do not exceed the rated 150 PSIG working pressure. Thread connections should be sealed with approved thread sealant or tape rated for potable water service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 150 PSIG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTank Capacity\u003c\/strong\u003e: 20 gallons\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiaphragm Material\u003c\/strong\u003e: Heavy-duty butyl\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShell Construction\u003c\/strong\u003e: Deep drawn steel, multi-dome\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExterior Coating\u003c\/strong\u003e: Tuf-Kote HG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem Connection Material\u003c\/strong\u003e: Stainless steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase Material\u003c\/strong\u003e: DuraBase composite (non-corrosive)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: 7-year limited\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: AMTROL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 399591\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AMTROL","offers":[{"title":"Default Title","offer_id":51467584176434,"sku":"399591","price":539.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313946507.jpg?v=1783907082","url":"https:\/\/voomisupply.com\/products\/amtrol-399591-well-x-trol-20-gallon-well-pressure-tank","provider":"Voomi Supply","version":"1.0","type":"link"}
