2. Water softening - Wikipedia

   en.wikipedia.org/wiki/Water_softening

   The resulting soft water requires less soap for the same cleaning effort, as soap is not wasted bonding with calcium ions. Soft water also extends the lifetime of plumbing by reducing or eliminating scale build-up in pipes and fittings. Water softening is usually achieved using lime softening or ion-exchange resins, but is increasingly being ...

3. Dealkalization of water - Wikipedia

   en.wikipedia.org/wiki/Dealkalization_of_water

   Chloride cycle dealkalizers operate similar to sodium cycle cation water softeners. Like water softeners, dealkalizers contain ion-exchange resins that are regenerated with a concentrated salt solution - NaCl. In the case of a water softener, the cation exchange resin is exchanging sodium (the Na + ion of NaCl) for hardness minerals such as ...

4. Air gap (plumbing) - Wikipedia

   en.wikipedia.org/wiki/Air_gap_(plumbing)

   Water cannot flow from the sink to the tap in normal circumstances, even if the water supply loses pressure. An air gap , as related to the plumbing trade, is the unobstructed vertical space between the water outlet and the flood level of a fixture . [ 1 ]

5. Backflow prevention device - Wikipedia

   en.wikipedia.org/wiki/Backflow_prevention_device

   Backflow prevention device. The simplest, most reliable way to provide backflow prevention is to provide an air gap.An air gap is simply an open vertical space between any device that connects to a plumbing system (like a valve or faucet) and any place where contaminated water can collect or pool.

6. Hard water - Wikipedia

   en.wikipedia.org/wiki/Hard_water

   A common method for water softening involves the use of ion-exchange resins, which replace ions like Ca 2+ by twice the number of mono cations such as sodium or potassium ions. Washing soda (sodium carbonate, Na 2 CO 3) is easily obtained and has long been used as a water softener for domestic laundry, in conjunction with the usual soap or ...
