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 and fittings.
Hard water is a fact of life across most of the U.S. Learn how to remove hard water stains and build-up in your home. ... How to clean your bathtub . Slow draining sink:How to fix a hideous clog.
A bathtub faucet with built-up calcification from hard water in Southern Arizona.. Hard water is water that has a high mineral content (in contrast with "soft water"). Hard water is formed when water percolates through deposits of limestone, chalk or gypsum, [1] which are largely made up of calcium and magnesium carbonates, bicarbonates and sulfates.
Hard water carries more minerals than soft, so if you live in an area with hard water, this could be the culprit. To get the hot water flowing again, drain the tank and consider installing a water ...
Also, the tortuous S-shaped path the water is forced to follow offers a significant obstruction to the flow. For high pressure domestic water systems this does not matter, but for low pressure systems where flow rate is important, such as a shower fed by a storage tank, a "stop tap" or, in engineering terms, a "gate valve" is preferred.
Review: "I’ve been scrubbing the tub weekly due to hard water and mineral stains. The only thing that worked before was abrasive cleaners and I didn’t want to scrub the clear coat off my new tub.
Due to its toxicity, most cities moved away from lead water-supply piping by the 1920s in the United States, [36] although lead pipes were approved by national plumbing codes into the 1980s, [37] and lead was used in plumbing solder for drinking water until it was banned in 1986. [36] Drain and vent lines are made of plastic, steel, cast iron ...
The 'bathtub' refers to the shape of a line that curves up at both ends, similar in shape to a bathtub. The bathtub curve has 3 regions: The first region has a decreasing failure rate due to early failures. The middle region is a constant failure rate due to random failures. The last region is an increasing failure rate due to wear-out failures.
