    Calci-Flush Tanked Water Heater Flush Descaler – Fast-Acting Scale & Calcium Removal Solution

    Available in 1 Gallon Jug or Case of 4 Gallons

    Extend the life, performance, and energy efficiency of your tanked water heater with Calci-Flush Water Heater Flush, a fast-acting professional-grade descaler designed to remove calcium, lime, and mineral scale buildup caused by hard water. Ideal for both residential and commercial tanked water heaters, Calci-Flush restores proper water flow, improves heating efficiency, and helps prevent premature heater failure.

    Over time, hard water mineral deposits accumulate inside tank-style water heaters, leading to reduced hot water output, low water pressure, longer recovery times, and increased energy costs. Calci-Flush works quickly to dissolve stubborn scale deposits, allowing your water heater to operate at peak performance again.

    Unlike vinegar or DIY water heater cleaning methods, Calci-Flush is a ready-to-use chemical descaler formulated specifically for water heater maintenance and flushing. It requires no mixing or dilution, works significantly faster than vinegar, and produces minimal odor, making it safe and convenient for use inside homes, apartments, and commercial buildings.

    Compatible with most standard gas and electric tanked water heaters, Calci-Flush makes routine water heater descaling and preventive maintenance simple and effective.
