Water systems of ancient times relied on gravity for the supply of water, using pipes or channels usually made of clay, lead, bamboo, wood, or stone. Hollowed wooden logs wrapped in steel banding were used for plumbing pipes, particularly water mains. Logs were used for water distribution in England close to 500 years ago. US cities began using hollowed logs in the late 1700s through the 1800s. Today, most plumbing supply pipe is made out of steel, copper, and plastic; most waste (also known as "soil")[21] out of steel, copper, plastic, and cast iron.[21]
It does help in regards to procedures and rules in order to better understand your options.  Obviously cost is always an issue and the size of the company probably determine the labor cost.  That is why some times people take chances with "others' hoping that there have good experience but because they are independent operators there pricing might be more flexible.

Plumbers develop blueprints to plan where pipes and fixtures should be plotted in a structure. They also install and connect the piping and fixtures, either working individually or with a team of apprentices and pipefitters. In addition to facilitating water supply from pipes and large fixtures, such as bathtubs, showers, sinks and toilets, plumbers ensure that water reaches appliances like dishwashers and water heaters. The best in the occupation are strong problem-solvers who have mastered customer service and can meet the physical and mechanical demands of the job.
Most states and localities require plumbers to be licensed. Although licensing requirements vary, most states and localities require workers to have 2 to 5 years of experience and to pass an exam that shows their knowledge of the trade and of local plumbing codes before they are permitted to work independently. In addition, most employers require plumbers to have a driver’s license.

Most recently they sent Mike out to snake a kitchen sink drain for us. Mike got here earlier than quoted and got the work done quickly so I could get out of work on time and pick up my little boy from daycare. I called them back to give a compliment about Mike. I like to let them know when they do a good job. Mike was really a great guy. I have nothing but good things to say about them. When we have an issue we call them. Their techs are personable and always make the residents laugh. They are clean and well prepared. It is a real stand up operation.

Wall thickness does not affect pipe or tubing size.[20] 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.[citation needed]
Keeping your trash dispoal clean isn't very difficult or time consuming. Fill the sink at least half full of soapy water. Remove the stopper from the drain while simultaneously turning on the disposal. This will fill the entire disposal with soapy water and help to flush out food buildup. It will also clean the blades and flush your pipes with clean water.
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.

Called at 2pm and had service completed by 6pm on a cold any busy day with lots of frozen pipes. Extremely fast and took the time to communicate both the issue, and associated costs of repair. Also very communicative for when someone would be by. Got an update call from the service center saying “we are a bit busy but you are still in the schedule for today”. Much appreciated so I could plan my afternoon while waiting. Highly recommended.
Much of the plumbing work in populated areas is regulated by government or quasi-government agencies due to the direct impact on the public's health, safety, and welfare. Plumbing installation and repair work on residences and other buildings generally must be done according to plumbing and building codes to protect the inhabitants of the buildings and to ensure safe, quality construction to future buyers. If permits are required for work, plumbing contractors typically secure them from the authorities on behalf of home or building owners.[citation needed]
