## Features

- Efficient scale inhibition This scale inhibitor's food-grade polyphosphate can inhibit limescale formation by preventing calcium and magnesium ions from precipitating and combining, and reduce corrosion by forming a protective layer on the inner surfaces of shower heads, water heaters, faucets, pipelines, and other pipelines.
- Energy saving Reducing limescale on heating elements extends lifespan of water heaters, washing machines, dishwashers, and other water-using appliances while also improving efficiency and saving energy.
- Premium materials The scale inhibitor system is made of food-grade, BPA-free materials and includes durable anti-rusting 304 stainless steel adapters.
- Stable flow 3/4”NPT inlet/outlet ensures a high flow rate of 10 GPM and keeps stable water pressure.
- Easy installation Please keep this inline scale inhibitor system upright. By absorbing a small amount of polyphosphate, this system can better inhibit the aculation of hard minerals on the surface of metal, ensuring a better scale inhibition effect. Please ensure that it is installed on a cold-water supply pipeline to supply water to the water heater..Long lifespan This system can offer 6-month protection under normal use, but the lifespan may vary based on local water quality.
