More effective than vinegar and safer than harsh chemical descalers — this tankless water heater flush kit pairs a powerful biodegradable powder descaler with a complete 4-piece hardware setup to tackle organic buildup, inorganic mineral scale, and corrosion deposits in a single 30-minute flush.

What's Included

• 3.5-gallon bucket with lid

Key Features & Benefits

• More powerful than vinegar — the powder descaler's concentrated chemistry outperforms acetic acid on heavy inorganic scale and mixed-deposit buildup
