For heavy scale buildup, hard water regions, or back-to-back professional jobs, a single quart of descaling solution isn't enough. This heavy-duty tankless water heater flush kit comes loaded with a full gallon of citric acid descaling solution — four times the volume of a standard kit — paired with premium stainless steel hoses built for repeated professional use.
What's Included
- 5-gallon bucket with lid
- 1/6 HP submersible pump
- 2 high-quality stainless steel hoses
- 1 gallon (128 fl oz) citric acid descaling solution

Key Features & Benefits

- Elevated pump grate — keeps the pump elevated for clean solution intake and consistent flow throughout a longer flush cycle
