The bottom line: this pump is best for property owners who want a rugged, quietly running unit that can move large volumes of water quickly and resist corrosion over time. Its strongest single advantage is the combination of a powerful 1\/3 HP motor and a cast iron construction that delivers up to 4,600 GPH while staying relatively quiet and clog-resistant.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh flow capacity:\u003c\/strong\u003e The 1\/3 HP motor can pump up to 4,600 GPH at 0', which moves large volumes of standing water quickly during heavy rain events.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable construction:\u003c\/strong\u003e Cast iron base with epoxy-coated steel motor housing and stainless steel fasteners provides corrosion resistance and long service life in sump applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTop suction design:\u003c\/strong\u003e The top suction intake helps minimize clogging from debris at the bottom of the sump pit and eliminates air lock problems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegrated vertical float switch:\u003c\/strong\u003e The vertical float switch is designed for long life and has been cycle-tested for extended durability, reducing the need for frequent replacement.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCode-compliant discharge:\u003c\/strong\u003e The 1-1\/2 NPT discharge fits common plumbing and meets building code expectations for many installations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEase of installation:\u003c\/strong\u003e Compact top-suction layout and a carry handle make it straightforward to set up in an 11 in or larger basin with minimal plumbing changes.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe WAYNE CDU790 is ideal for homeowners with basements or crawlspaces that are prone to significant water intrusion from heavy rain or snowmelt who want a durable, high-capacity sump solution.
