It’s a family event in late October when many American households carve a pumpkin into a Halloween jack-o-lantern. The kids delight in the whole process, especially when mom and dad let junior scoop the pumpkin pulp out of the pumpkin. But what happens next is the scary part. Often, those slimy pumpkin guts are pushed down the sink drain then the disposal is turned on to chop it into tiny bits before the water washes it away. Except, it doesn’t quite ... Read More >
I just had my pipe under the sink unclogged and new pipes put in $600.00, then they flushed out the pipe from under the sink to the outside pipe $700.00, Total of $1.600.00, I thought that the price was high, I got the plumber from Home Advisors, not sure they had to do all they did but they said I needed the work done. The same evening hike using the dishwasher I had a leak in one of the pipes they put in, they came back the next day to fix it. Don't know if I will use them again.. They were K&D kitchens.
Wall thickness does not affect pipe or tubing size. 1/2" L copper has the same outer diameter as 1/2" K or M copper. The same applies to pipe schedules. As a result, a slight increase in pressure losses is realized due to a decrease in flowpath as wall thickness is increased. In other words, 1 foot of 1/2" L copper has slightly less volume than 1 foot of 1/2 M copper.
The straight sections of plumbing systems are called "pipes" or "tubes". A pipe is typically formed via casting or welding, whereas a tube is made through extrusion. Pipe normally has thicker walls and may be threaded or welded, while tubing is thinner-walled and requires special joining techniques such as brazing, compression fitting, crimping, or for plastics, solvent welding. These joining techniques are discussed in more detail in the piping and plumbing fittings article.
As with other construction workers, employment of plumbers, pipefitters, and steamfitters is sensitive to fluctuations in the economy. On the one hand, workers may experience periods of unemployment when the overall level of construction falls. On the other hand, shortages of workers may occur in some areas during peak periods of building activity.
When a person has a blockage in their sewage system they often try to fix it themselves by adding an acid or a base such as Drano in an attempt to dissolve or dislodge the problem. These chemicals can get into the plumbers eyes when the sewage is splashed during the repair. The plumbers skin during the repair does come into contact with the sewage water. The owner of the toilet might not report to the plumber they have already tried Drano a highly caustic base .
