{"product_id":"watts-0204158","title":"Watts LFUSG-CS 3\/8\" Lead-Free Thermostatic Mixing Valve","description":"\u003cp\u003eThe Watts LFUSG-CS is a 3\/8\" lead-free Under Sink Guardian point-of-use mixing valve. It blends hot and cold water to hold a field-adjustable outlet temperature of 80°F to 120°F. It is listed to ASSE 1070. It features a epdm seat. Rated to 150 psi. This model is certified lead-free for potable-water installations.\u003c\/p\u003e\u003cp\u003eThis Under Sink Guardian® mixing valve with Cross Sense™, is built to maintain a steady and safe water temperature at the fixture making it an ideal solution for facilities that prioritize user protection, such as hospitals, schools, businesses, and elder care homes. Designed for installation beneath sinks or counters, it helps prevent accidental scalding from overheated water. With its enhanced flow dynamics, the Under Sink Guardian ensures precise temperature regulation with minimal pressure loss. Internally, dual check valves prevent reverse flow between hot and cold supplies, while integrated strainers trap particles. Both housed within a removable, serviceable cartridge that promotes long-term maintenance and sustainability. The Cross Sense feature uses temperature-sensitive indicators to provide a clear visual of any cross-connection at the inlets.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAccurate temperature control with low pressure drop\u003c\/li\u003e\n\u003cli\u003eQuick change cartridge with integrated check valves and screens\u003c\/li\u003e\n\u003cli\u003eCross Sense feature uses color changing visual indicators to detect cross-connection at hot and cold inlets\u003c\/li\u003e\n\u003cli\u003eASSE 1070 listed and CSA certified\u003c\/li\u003e\n\u003cli\u003eMeets the reduced Q test statistic criteria of 0.5 ppb for lead per Section 9.5.1.1 of NSF\/ANSI\/CAN 61\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\u003c\/p\u003e\u003cdl\u003e\n\u003cdt\u003e\u003cstrong\u003eCan I use this at a lavatory — is it ASSE 1070 listed?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eYes. This valve is listed to ASSE 1070, the standard for point-of-use scald protection, so it is legal to install it serving a lavatory, sink or similar fixture. Its outlet adjusts from 80°F to 120°F. Note ASSE 1070 does not cover showers — an in-shower device must be ASSE 1016 listed.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eWhat temperature range does it deliver?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eThe outlet temperature is field-adjustable from 80°F to 120°F.
