The Effects of Hard Water on Your Plumbing

Platinum Series: For Hard Water

Hard water causes scale build-up on your pipes, water heaters and water-based appliances. Eventually they become clogged and damaged. Hard water interferes with every water-using appliance in the house. Hard water causes a film on glass shower doors, shower walls, bathtubs, sinks, faucets, etc. Dishes and glasses may be spotted when dry. Bathing with soap in hard water leaves a film of sticky soap curd on the skin, which can prevent complete removal of soil and bacteria. Clothes laundered in hard water may look dingy and feel harsh and scratchy.

Scale buildup from hard water can cause:

  • Reduced water pressure
  • “Frozen” valves on faucets
  • Crusted rings in toilet tanks
  • Poor sudsing of soaps, detergents and shampoos

Performance decreases in water-using appliances

The facts are indisputable: hard water causes scale build-up, and scale build-up causes problems that result in wasted dollars. Water heater inefficiency is just one of these problems. Scale reduces the water flow and decreases heat transfer. The estimated energy cost for running a 40-gallon electric hot water heater is $450 each year. A scale build-up of just ⅜” gobbles up 55 percent more energy, according to the U.S. Bureau of Standards. That’s an additional $247 or more each year to produce the same amount of hot water.
