Condensate from modulating furnaces, boilers, and tankless water heaters typically falls below a pH of 6.0, making it corrosive to cast-iron drains and municipal sewer systems. This unit handles appliance condensate flow up to 1.9 gallons per hour and is rated for systems up to 500,000 BTU\/h. The refillable tank design gives technicians a cost-effective serviceability option, while the included throwaway canister provides an alternative single-use configuration. Licensed HVAC and plumbing contractors are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThe 4720-12 is built for residential and light-commercial applications where high-efficiency, fuel-fired equipment generates acidic condensate requiring treatment before drain discharge. Compatible equipment types include condensing boilers, high-efficiency fuel-fired furnaces, and tankless water heaters. The unit mounts horizontally and connects via 3\/8-inch female NPT fittings on two inlets, making it straightforward to tie into existing condensate drain lines. The integrated submersible self-priming pump flows up to 74 gallons per hour at free flow and 32 gallons per hour at 20 feet of head, supporting a range of drainage configurations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRefillable tank design allows media replacement without full unit changeout, reducing long-term service cost\u003c\/li\u003e\n  \u003cli\u003eThrowaway canister included for single-use installations where refilling is not preferred\u003c\/li\u003e\n  \u003cli\u003eOffset female NPT fittings on two inlets simplify condensate line connections\u003c\/li\u003e\n  \u003cli\u003eIntegrated 120V AC submersible self-priming pump rated at 74 gph free flow and 32 gph at 20 feet of head\u003c\/li\u003e\n  \u003cli\u003eHorizontal mounting orientation suits typical equipment room layouts\u003c\/li\u003e\n  \u003cli\u003ecETLus Listed to ANSI\/UL STD 778 and CAN\/CSA STD C22.2 No. 108 for confidence in listed installations\u003c\/li\u003e\n  \u003cli\u003eMedia service life of approximately one year when pH drops below 6, with annual treatment frequency recommended\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with condensing boilers, high-efficiency fuel-fired furnaces, and tankless water heaters generating acidic condensate, with a maximum appliance condensate flow rating of 1.9 gph and a system capacity up to 500,000 BTU\/h.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed HVAC technician or plumber. Shut off the appliance and isolate the condensate drain line before making connections. Connections are 3\/8-inch female NPT; use appropriate thread sealant rated for acidic condensate service. Verify local plumbing code requirements for condensate discharge, as some jurisdictions require neutralization before drain entry. The pump requires a 120V AC power source; confirm the outlet is properly grounded per NEC guidelines before energizing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAppliance Capacity\u003c\/strong\u003e: 500,000 BTU\/h\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCondensate Flow Rate\u003c\/strong\u003e: 1.9 gph\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePump Voltage\u003c\/strong\u003e: 120V AC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePump Type\u003c\/strong\u003e: Submersible Self-Priming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePump Flow Rate\u003c\/strong\u003e: 74 gph free flow; 32 gph at 20 feet of head\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Female NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Inlets\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContainer Length\u003c\/strong\u003e: 15.8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContainer Width\u003c\/strong\u003e: 5.3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContainer Height\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Orientation\u003c\/strong\u003e: Horizontal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMedia Container Type\u003c\/strong\u003e: Tank\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRefillable\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMedia Service Life\u003c\/strong\u003e: 1 year when pH falls below 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTreatment Frequency\u003c\/strong\u003e: Annual\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\/UL STD 778, CAN\/CSA STD C22.2 No. 108, cETLus Listed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: Canada\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NU-CALGON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4720-12-01 00:00:00\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NU-CALGON","offers":[{"title":"Default Title","offer_id":51468211355954,"sku":"4720-12","price":324.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313945545.jpg?v=1783914604","url":"https:\/\/voomisupply.com\/products\/nu-calgon-4720-12-condensate-neutralizer-500000-btu-h","provider":"Voomi Supply","version":"1.0","type":"link"}
