The most complete tankless water heater flush kit on the market — everything you need arrives in a single box, including right angle hoses for tight-space connections and a pump with a 25-foot power cord so you're never hunting for an outlet. This is the all-in-one flushing kit built for convenience, reach, and results.

What's Included

• 5-gallon bucket with lid
• 1/6 HP submersible pump with 25 ft power cord
• 2 right angle steel inlet hoses
• 1 qt (32 fl oz) citric acid descaling solution
• Elevated pump grate

Key Features & Benefits

• 25-foot pump cord — reach any outlet in the utility room, garage, or basement without an extension cord
• Right angle steel hoses — engineered for service ports in tight spaces where straight hoses won't seat properly; connects cleanly even in cramped mechanical rooms
• Citric acid descaling solution included — 1 qt (32 fl oz) of professional-grade formula dissolves mineral scale, calcium, and lime deposits on contact
• Elevated pump grate — keeps the pump off the bucket floor for consistent solution intake and longer pump life
• Complete and ready to use — no separate purchases needed; open the box and start flushing
• Flush in 30 minutes or less — restores flow rate and heat efficiency without calling a plumber
