Manufactured under the McDonnell Miller line, this valve allows technicians to verify check valve operation without removing the component from the line, reducing service time and system downtime. The combined test-and-check function consolidates two service steps into one accessible fitting. Licensed plumbers and HVAC technicians working on low-pressure hot water boiler systems rely on this valve for both routine maintenance and compliance inspections.\u003c\/p\u003e\n\u003cp\u003eThis valve is suited for residential and light commercial hydronic heating applications, including boiler makeup water lines and feedwater assemblies where backflow protection is required by code. The 1-inch connection size fits standard piping configurations common in boiler rooms and mechanical spaces. The set-of-two configuration supports installations requiring paired or redundant check points within the same system.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIntegrated test-and-check design allows in-line operational verification without line removal\u003c\/li\u003e\n  \u003cli\u003e1-inch connection size fits standard hydronic and boiler feedwater piping\u003c\/li\u003e\n  \u003cli\u003eSold as a set of two valves for complete installation or paired replacement\u003c\/li\u003e\n  \u003cli\u003eMcDonnell Miller product line, a recognized name in boiler water management\u003c\/li\u003e\n  \u003cli\u003eCombined weight of 6.9 pounds for the set\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation component for 1-inch hydronic boiler feedwater and makeup water piping systems requiring integrated test and backflow check functionality.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or qualified HVAC technician familiar with hydronic boiler systems and local plumbing codes.
