  2. Leak detection - Wikipedia

    en.wikipedia.org/wiki/Leak_detection

    If a leak occurs, the substances to be measured come into contact with the tube in the form of vapour, gas or dissolved in water. In the event of a leak, some of the leaking substance diffuses into the tube. After a certain period of time, the inside of the tube produces an accurate image of the substances surrounding the tube.

  3. Dealkalization of water - Wikipedia

    en.wikipedia.org/wiki/Dealkalization_of_water

    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 calcium and magnesium.

  4. Sewer gas - Wikipedia

    en.wikipedia.org/wiki/Sewer_gas

    The result is the most common means of sewer gas entering buildings and can be solved easily by using the fixtures regularly or adding water to their drains. One of the most common traps to dry out are floor drains such as those typically placed near home furnaces, water heaters and rooms with underfloor heating. Infrequently used utility sinks ...

  6. Tank leak detection - Wikipedia

    en.wikipedia.org/wiki/Tank_leak_detection

    Tank leak detection is implemented to alert the operator to a suspected release from any part of a storage tank system, what enables to prevent from soil contamination and loss of product. In many countries regulated UST are required to have an approved leak detection method so that leaks are discovered quickly and the release is stopped in time.

  8. Hydrostatic test - Wikipedia

    en.wikipedia.org/wiki/Hydrostatic_test

    A hydrostatic test is a way in which pressure vessels such as pipelines, plumbing, gas cylinders, boilers and fuel tanks can be tested for strength and leaks. The test involves filling the vessel or pipe system with a liquid, usually water, which may be dyed to aid in visual leak detection , and pressurization of the vessel to the specified ...

  9. Water softening - Wikipedia

    en.wikipedia.org/wiki/Water_softening

    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
