The Watts Premier TAC (Template Assisted Crystallization) Cartridge is a highly efficient solution for reducing scale formation, ensuring your appliances operate smoothly and extending their lifespan. Rated for up to an impressive 250,000 gallons, this cartridge provides long-lasting performance and reliable scale protection without the use of chemicals. Designed to convert hard minerals into harmless soft particles, the TAC cartridge effectively prevents scale build-up inside pipes and appliances while retaining essential minerals such as calcium, potassium, and magnesium. One of the standout features of the Watts Premier TAC Cartridge is its environmentally friendly design. Unlike traditional water softeners that use salt and chemicals, this cartridge operates without adding or removing anything from the water. Specifically crafted for use with the Watts Premier OneFlow Plus Whole House system, this replacement cartridge is an integral component of your home water filtration setup. By maintaining the natural composition of the water and preventing scale formation, the TAC cartridge helps improve the efficiency of water used in various household appliances, leading to fewer maintenance issues and longer-lasting appliances. In addition, installation and maintenance are straightforward with the Watts Premier TAC Cartridge. We recommend replacing the cartridge every 250,000 gallons or every three years, whichever comes first, to ensure optimal performance. When it's time for replacement, simply turn off the inlet and outlet valves on the system's supply and outlet lines to safely swap out the old cartridge for a new one.
