  • The importance of pH in steam-boiler water

    Jun 24, 2014 · And even if you fix the leaks in the system, you still have to keep an eye on the pH of the water because many people add chemicals to their boilers to avoid corrosion. These chemicals shove the pH toward the alkaline side of the scale. When the pH reaches 10, corrosion becomes impossible. That's what makes chemical drain cleaners safe for pipes.Get Price
