When water is heated, its volume increases. In a system where a check valve, pressure-reducing valve, or backflow device prevents that expanded volume from moving back toward the supply, pressure can rise rapidly. The tank provides a sealed air cushion that accepts the expanded water and helps keep system pressure within the intended operating range.\u003c\/p\u003e\n\u003cp\u003eA fixed butyl diaphragm separates the water from the precharged air chamber, while an FDA-grade polypropylene liner helps prevent water from contacting the carbon-steel shell. The almond-finished tank includes a 3\/4 in. 304 stainless steel system connection, a 35 PSI factory precharge, and a 150 PSI maximum design pressure. Correct sizing and precharge adjustment depend on water-heater capacity, supply pressure, temperature, and system configuration.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e10-gallon thermal expansion tank\u003c\/li\u003e\n\u003cli\u003eFixed butyl diaphragm\u003c\/li\u003e\n\u003cli\u003ePolypropylene water-side liner\u003c\/li\u003e\n\u003cli\u003eCarbon-steel shell\u003c\/li\u003e\n\u003cli\u003e3\/4 in. stainless steel connection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eTechnical Specifications:\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight:\u003c\/strong\u003e 20 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter:\u003c\/strong\u003e 11-1\/2 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFactory Precharge:\u003c\/strong\u003e 35 PSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Design Pressure:\u003c\/strong\u003e 150 PSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Design Temperature:\u003c\/strong\u003e 200°F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Almond\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eInstallation Notes:\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eInstall on the cold-water side of a compatible water-heating system.
