In short

The Hot Metal is the salt-free scale inhibitor in the Three Rivers lineup: specialized media inhibits hard water minerals from sticking to plumbing and appliances, with built-in carbon filtration and virtually no maintenance. It prevents limescale without salt, electricity or a drain, and without removing hardness minerals. Three Rivers installs it across the Greater Pittsburgh area.

Stop the buildup with The Hot Metal, our low-maintenance system that inhibits hard water minerals from sticking to your plumbing and appliances. Specialized media treats water on demand: the easiest way to prevent limescale.

  • Scale Reduction Media: Specialized media alters the state of calcium and magnesium hardness minerals so they are far less likely to form scale.
  • High Capacity Carbon: Effectively reduces the bad taste and odor from harsh chemicals.

Why choose The Hot Metal

Low Maintenance Fast-Acting Media Salt-Free System

How it differs from The Smithfield: same scale reduction media and carbon; The Smithfield adds bacteria-control media as a third layer. And the standing rule applies to both: inhibition is not softening.

Specifications

  • On-Demand Treatment with No Salt Needed.
  • Multi-Purpose: built-in filtration; Safety is Standard.
