I was disappointed with the pressure of a tub and shower that were plumbed with 1/2 supply lines (2nd floor). Could be low pressure from the street, but I want to replace with 5/8. Plus, I'd like to have 2 back to back showers, one inside and one outside. So, I had intended to bring a 1 supply to both, then branch up to valves and shower head with 5/8. Finally, I thought pressure from the street was typically 55 to 70 psi and I am concerned if pvc can take that.Any thoughts?
Several types of pipe were used during the nineteenth century. With little or no knowledge of its possible long-term harmful effects, lead pipe was widely used. Its low price and the ease with which it could be formed and joined made it the material of choice for many installations. Iron, brass, and copper pipe were used as well. It was not unusual for a structure to be plumbed with several types of pipe, each used where it was most suited. But by the early twentieth century there was a move away from lead piping. The basic elements of domestic plumbing, in both the kitchen and bathroom, were in place by the 1890s. Changes since that time have been primarily aesthetic and in the materials used. During the second half of the twentieth century, tubs and basins that previously had been made of glazed ceramic or enameled iron, and much of the pipe manufactured in the United States as well, were being made of plastic.
For many centuries, lead was the favoured material for water pipes, 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.) This was a source of lead-related health problems in the years before the health hazards of ingesting lead were fully understood; among these were stillbirths and high rates of infant mortality. Lead water pipes were still widely used in the early 20th century, and remain in many households. In addition, lead-tin alloy solder was commonly used to join copper pipes, but modern practice uses tin-antimony alloy solder instead, in order to eliminate lead hazards.[13]

Present-day water-supply systems use a network of high-pressure pumps, and pipes in buildings are now made of copper,[25] brass, plastic (particularly cross-linked polyethylene called PEX, which is estimated to be used in 60% of single-family homes[26]), or other nontoxic material. Due to its toxicity, most cities moved away from lead water-supply piping by the 1920s in the United States,[27] although lead pipes were approved by national plumbing codes into the 1980s,[28] and lead was used in plumbing solder for drinking water until it was banned in 1986.[27] Drain and vent lines are made of plastic, steel, cast-iron, or lead.[29][30]
General employment within the construction sector is sensitive to changes in the economy. But job growth for plumbers is projected to be faster than the average for all jobs. New buildings and residences are being built to comply with stricter water efficiency standards and companies housed in older structures are hoping to retrofit to use more energy-efficient systems, so opportunities are in abundance. According to the Bureau of Labor Statistics, there should be a hiring spurt of 16 percent for plumbers by the year 2026, which translates to about 75,800 new jobs.

Working as one harmonious unit, the two pipe networks which make up your residential plumbing system have very specific functions: whereas water pipes supply fresh water to your home, the drain system (known as DWV) takes out contaminated water. To ensure the harmonious flow of your plumbing system, ask your local plumber to perform routine maintenance checks.

Where plumbing had been a mostly locally regulated matter for most of its history, the federal government became involved in the early 1990s. Until the 1950s, toilets generally used five or more gallons per flush (GPF). During the decades that followed, the plumbing industry reduced the standard volume for toilet flush tanks to 3.5 gallons. A further reduction in volume resulted from the Energy Policy Act of 1992, which in the name of conservation mandated that all new toilets made in the United States must use no more than 1.6 GPF. The same legislation also regulated the flow in shower heads and faucets. Although the first low-flow toilets proved un-satisfactory and were met with public disapproval, redesigned equipment employing new technology has removed most objections.
Those who attempted to bring plumbing indoors faced technical as well as attitudinal challenges. Decisions on how wastewater was removed required as much concern as those made to ensure an adequate water supply. But equally vexing was the prevailing miasma theory of disease, which held that illnesses stemmed from "bad air" that was readily identifiable by its offensive odor. This led to a distrust of early indoor plumbing that tended to leak and a deadly fear of the sewer gas that accompanied the leaks. It is no wonder then that many individuals maintained a strong belief that elimination was best taken care of out of doors.
