plumbing, piping systems inside buildings for water supply and sewage. The Romans had a highly developed plumbing system; water was brought to Rome by aqueducts and distributed to homes in lead pipes—hence the name plumbing from the Latin word plumbum for lead. During the Middle Ages, however, plumbing became almost nonexistent. In fact, London's first water system after the Middle Ages (c.1515) consisted partly of the rehabilitated Roman system; the rest was patterned after it. Modern plumbing began in the early 1800s, when steam engines became capable of supplying water under pressure and cheap cast iron pipes could be supplied to carry it. The common materials used today in water supply pipes are steel, copper, brass, plastic, and lead. Plumbing for sewage is made of cast iron, steel, asbestos cement, copper, and plastic. Water pressure is usually insufficient to supply the needs of tall apartment and office buildings; in such cases storage tanks are installed on the roof, into which a pump lifts water. The water then flows through the piping system of the building by gravity. Smaller buildings may have a pneumatic tank for the same purpose. The tank is partly filled with air, which is compressed when water is pumped in so that it will force water through the pipes. Sewage and drain systems typically have a trap, often a loop-shaped section of pipe, to seal off vapors in the pipes from the rest of the building. Vent pipes lead these vapors to the outside of the building; they also eliminate any suction in the piping and thus prevent the siphoning of water from traps when a nearby fixture discharges. In the 1970s and 80s flexible polybutylene plumbing was widely installed in standard and mobile homes. When unprecedented numbers of these plastic pipes began leaking because of exposure to chlorine and other chemicals in tap water, homeowners brought class-action lawsuits against the manufacturers, which were settled in 1995 for hundreds of millions of dollars.
Don R. is a “Superstar”! He quickly identified the outdated timer attached to our water that was malfunctioning, as it was making a very annoying grinding sound. He disconnected the timer and rerouted the power cable to the water heater. The problem was solved instantaneously. Moreover, Don had provided us with some useful information that we deemed valuable as well. Don, we truly appreciate your top notch service.P.S. You have restored peace back into my household.
Plumbers may not go out of their way to let you know that a toilet or sink can be moved. But if you’ve been working with them on a renovation, and they tell you something can’t be transferred to a new space, ask them to explain to you in detail why not. Speaking of things people don’t want to tell you, here are 10 things your neighbor isn’t being up-front about.
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?
