Solving The Hard Water Problem

A Guide To Water Softeners

Water softener systems are an easy, effective as well as economical way to turn hard water soft. These appliances come in a variety of sizes and shapes to meet different needs and issues in your house. Water softener systems are installed alongside your plumbing, converting hard water to soft before it’s delivered through the taps. The salt-based water softeners can be either electricity driven or non-electricity driven.

The most common water softeners operate through a process known as ion-exchange. They contain resin beads with sodium salts. Hard water passes through the resin beads, replacing mineral elements such as calcium and magnesium with sodium thus being able to soften water. Some of the available house appliances can also use a magnetic field or potassium chloride instead of sodium.

Points before investing in a water softener:

  • The water softening capacity of the appliance
  • The amount and type of water and salt used during regeneration cycles
  • How much water the unit will soften each day
  • Cost of the softener
  • Your existing pipework
  • Ease of use as well as maintenance
  • Softener manufacturer warranty
