Why is there a crusty white buildup on my faucets? The white, chalky buildup on your faucets is called limescale, and it is caused by hard water. When water passes through natural rock formations like limestone, it dissolves and picks up high levels of minerals—primarily calcium and magnesium. When hard water drips, splashes, or evaporates on your plumbing fixtures, it leaves these heavy minerals behind. Over time, they bake onto the surface and form a rock-hard crust. Aside from looking unsightly, limescale buildup can: – Destroy water using appliances like your dishwasher, clothes washer, water heater, ice maker, etc. leading to expensive repairs/ replacement. – Clog aerators and severely reduce your water pressure. – Corrode finishes and permanently ruin the look of your expensive fixtures. – Destroy internal valves, causing your faucets to leak or stiffen up. – Leave soap residue and hard spots on dishes, coffee pots, shower doors, windows, etc. The only way to completely stop scale from destroying your fixtures (and appliances) is to remove the minerals at the source. A high-efficiency water softener eliminates calcium and magnesium from your water supply entirely, keeping your faucets sparkling clean and extending the lifespan of your plumbing.
