  2. Lead service line - Wikipedia

    en.wikipedia.org/wiki/Lead_service_line

    The second part is the pipe that connects the curb stop to the building inlet or a water meter. This part is called supply pipe. Depending on local water utilities, the meter may be located at the property line instead. When the water meter is located at that alternative position, the pipe section that connects the water main to the water meter ...

  3. Flint water crisis - Wikipedia

    From August 2015 to November 2016, median water lead levels began to go down again depending on the type of water service pipes each home had. In homes with copper pipes, the median water lead level dropped from 3.0 micrograms per liter (μg/L) to <1 μg/L; galvanized steel service lines dropped from a median water lead level of 7.2 μg/L to 1. ...

    EPA illustration of lead sources in residential buildings Infographic about lead in drinking water. The Lead and Copper Rule (LCR) is a United States federal regulation that limits the concentration of lead and copper allowed in public drinking water at the consumer's tap, as well as limiting the permissible amount of pipe corrosion occurring due to the water itself.

  5. Water damage - Wikipedia

    en.wikipedia.org/wiki/Water_damage

    An insurance policy may or may not cover the costs associated with water damage and the process of water damage restoration. While a common cause of residential water damage is often the failure of a sump pump, many homeowner's insurance policies do not cover the associated costs without an addendum which adds to the monthly premium of the policy.

  6. Galvanization - Wikipedia

    en.wikipedia.org/wiki/Galvanization

    These plaques can flake off, leading to visible impurities in water and a slight metallic taste. The life expectancy of galvanized piping is about 40–50 years, [12] but it may vary on how well the pipes were built and installed. Pipe longevity also depends on the thickness of zinc in the original galvanizing, which ranges on a scale from G01 ...

  7. Galvanic corrosion - Wikipedia

    en.wikipedia.org/wiki/Galvanic_corrosion

    Galvanized mild steel cable ladder with corrosion around stainless steel bolts. All metals can be classified into a galvanic series representing the electrical potential they develop in a given electrolyte against a standard reference electrode. The relative position of two metals on such a series gives a good indication of which metal is more ...

  8. Plumbing - Wikipedia

    en.wikipedia.org/wiki/Plumbing

    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.

  9. Chemical drain cleaners - Wikipedia

    en.wikipedia.org/wiki/Chemical_drain_cleaners

    Once corrosion occurred down to the base metal, plaques and rust would form, leading to sediment build-up that would gradually clog these drains. Thus, the first motivation for drain cleaners came to be. The struggle against corroding galvanized iron pipes eventually led to a replacement by copper or plastic (PVC) piping by the 1960s.
