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.
In the United Kingdom the professional body is the Chartered Institute of Plumbing and Heating Engineering (educational charity status) and it is true that the trade still remains virtually ungoverned;[40] there are no systems in place to monitor or control the activities of unqualified plumbers or those home owners who choose to undertake installation and maintenance works themselves, despite the health and safety issues which arise from such works when they are undertaken incorrectly; see Health Aspects of Plumbing (HAP) published jointly by the World Health Organization (WHO) and the World Plumbing Council (WPC).[41][42] WPC has subsequently appointed a representative to the World Health Organization to take forward various projects related to Health Aspects of Plumbing.[43]
This was Roberts fourth visit to her home, each time for different services and Zach‘s first. As always Tiffany in the office as well as the rest of the staff are more than communicative prior to the visit and keep you up-to-date on the travel time of the technician. The technicians are friendly, intelligent, accommodating, and beyond respectful and neat. I highly recommend Atomic Plumbing for any residential or commercial needs and would like to thank them for their personalized attention to our home.
When you wash up before bed or take a nice, hot shower before heading off to work in the morning, it is your plumbing system that you are relying on. The same is true when you run your dishwasher or laundry machine. To say that your plumbing system plays a major role throughout the day, every day, in your home is to make a massive understatement. That is why it is so vital that you are able to use your plumbing system reliably, which in turn means that you must hire professional plumbers that you can count on to do the job right, such as those on our fine staff.

Despite the Romans' common use of lead pipes, their aqueducts rarely poisoned people. Unlike other parts of the world where lead pipes cause poisoning, the Roman water had so much calcium in it that a layer of plaque prevented the water contacting the lead itself. What often causes confusion is the large amount of evidence of widespread lead poisoning, particularly amongst those who would have had easy access to piped water.[14] This was an unfortunate result of lead being used in cookware and as an additive to processed food and drink, for example as a preservative in wine.[15] Roman lead pipe inscriptions provided information on the owner to prevent water theft.
An apprenticeship is the most common pathway to becoming a plumber. Many unions and businesses mandate that an apprentice receive a minimum of 246 hours of technical education, which could include instruction in math, applied physics and chemistry, and up to 2,000 hours of paid, practical training working with an experienced plumber. Safety training is also an important component of the process, since injuries are common in this line of work. "We have many hours worth of [Occupational Safety and Health Administration] training before we go on to a job site," says Patrick Kellett, the administrative assistant to the general president for the United Association of Journeymen and Apprentices of the Plumbing, Pipe Fitting Industry of the United States, Canada and Australia. "We're very conscious of the dangers that come with working in construction."

 Jimmy P removed a 6 inch diameter root that had grown around my main water line. He was diligent in finding our the cause of the leak, kept me informed throughout the process and made sure that I was up and running with water for my family in less than an 8 hour period. It was a huge undertaking. Jimmy P was first class and polite . The had the necessary experience that was needed to get this water main break under control. He made the best of a horrible situation. Extremely pleasant and talented. I would highly suggest that all of my friends request Jimmy P at ATOMIC!

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]
