{"product_id":"watts-88003377","title":"Watts LF709-NRS-S-IOT 3 Lead-Free Double Check Backflow Preventer, Cast Iron","description":"\u003cp\u003eThe Watts LF709-NRS-S-IOT 3 is a 3\" lead-free double check valve assembly, approved for low health hazard protection. It features a cast iron body. Rated to 175 psi. This model is certified lead-free for potable-water installations.\u003c\/p\u003e\u003cp\u003eThis 3 inch lead free double check valve backflow preventer assembly is designed to prevent the reverse flow of contaminated water of non-potable quality from being pumped or siphoned into the potable water supply due to backsiphonage and or backpressure. Ideal for protection in continuous pressure piping applications and cross-connections identified as non-health hazards. This assembly consists of a fused epoxy coated cast iron body, NRS resilient seated gate valves, strainer, test cocks, and a modular check design for easy maintenance with center stem guide. The captured spring is accessible through a bolted cover plate. This assembly features integrated pressure-sensing test cocks that measure pressure fluctuations at three points when activated with an add-on monitoring connection kit. The kit collects, converts, and transmits the data values for use in a building management system. The coating on this backflow assembly uses ArmorTek®, a patented 3-part advanced epoxy coating system designed to limit both microbial induced (MIC) and exposed metal substrate corrosion.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003ePressure sensors integrated on the backflow preventer to measure pressure fluctuations at three test cock locations when activated\u003c\/li\u003e\n\u003cli\u003eAdd-on kit available for activating sensors and transmitting data values to a building management system\u003c\/li\u003e\n\u003cli\u003eA solution for monitoring assembly performance between code testing\u003c\/li\u003e\n\u003cli\u003eData access to help drive scheduling of maintenance and repair\u003c\/li\u003e\n\u003cli\u003eUtilizes advanced ArmorTek coating technology to resist corrosion of internals\u003c\/li\u003e\n\u003cli\u003eCast iron body construction with patented 3-part advanced epoxy coating system designed to limit both microbial induced (MIC) and exposed metal substrate corrosion\u003c\/li\u003e\n\u003cli\u003eNon-rising stem gate valves\u003c\/li\u003e\n\u003cli\u003eIncludes: Test Cocks\u003c\/li\u003e\n\u003cli\u003eIncludes: Strainer\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\u003c\/p\u003e\u003cdl\u003e\n\u003cdt\u003e\u003cstrong\u003eWhat hazard level is this Double Check approved for?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eIt is rated for low health hazard (non-toxic, \"pollutant\") cross-connections only.
