Water softening is the removal of calcium, magnesium, and certain other metal cations in hard water. 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
As this type of stretcher is usually used by pulling rather than levering, it tends to leave the webbing slacker than traditionally expected. The pins can also damage the webbing, if used to apply an adequate force. This type is commonly used for making cheap furniture, where rubber webs are stapled permanently into place. As rubber only ...
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 ...
Ion exchange is a method widely used in household filters to produce soft water for the benefit of laundry detergents, soaps, and water heaters. This is accomplished by exchanging divalent cations (such as calcium Ca 2+ and magnesium Mg 2+) with highly soluble monovalent cations (e.g., Na + or H +) (see water softening).
Placing bowls of water near sunny windows or on a radiator can actually help. As the water evaporates, it adds moisture to the room," he says. "If you’re feeling decorative, add some stones or ...
Old water pipe, remnant of the Machine de Marly near Versailles, France. Lead was the favoured material for water pipes for many centuries because its malleability made it practical to work into the desired shape. Such use was so common that the word "plumbing" derives from plumbum, the Latin word for lead.

The most popular webbing width is 25 mm (1 in) [2] but 38 mm (1.5 in) and 50 mm (2 in) are also very common. Narrower webbing is frequently looped through chock stones, which are jammed into cracks as safety anchors. In other cases, webbing is looped over rock outcroppings. Webbing is less likely to loosen itself off the rock than tubular rope.
