Bacteria have been shown to live in "premises plumbing systems". The latter refers to the "pipes and fixtures within a building that transport water to taps after it is delivered by the utility". Community water systems have been known for centuries to spread waterborne diseases like typhoid and cholera, however "opportunistic premises plumbing pathogens" have been recognized only more recently; Legionella pneumophila discovered in 1976, Mycobacterium avium, and Pseudomonas aeruginosa are the most commonly tracked bacteria, which people with depressed immunity can inhale or ingest and may become infected with. These opportunistic pathogens can grow for example in faucets, shower heads, water heaters and along pipe walls. Reasons that favor their growth are "high surface-to-volume ratio, intermittent stagnation, low disinfectant residual, and warming cycles". A high surface-to-volume ratio, i.e. a relatively large surface area allows the bacteria to form a biofilm, which protects them from disinfection.
No plumber is going to come right out and explain that they don’t have the required license to work for you. So if you know someone who is a great plumber, but they don’t have a license, hire them at your own risk. Licensed plumbers know the local building codes and regulations, have completed a certain amount of hours on the job and are insured. Want to become a master plumber yourself? Here are 28 tips.
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.
I used Go Green Express Home Services for a minor plastic pipe repair under my kitchen sink...The worker did a great job fixing this minor pipe plastic pipe repair( my original pipe was too short and he needed to extended the pipe and then reconnect). It took him less than 10 minutes to fix. I was first quoted $125 +tax but when the worker went to his truck and spoke to whoever he spoke to at the office, the price rose to $155.10 +tax for a total of $167.10...I thought that was a little too high. Will I use this company again, I Don't Know. It would be helpful if they would have a set price list for jobs (minor repairs, Major repairs etc...), then you as the consumer can see beforehand what the cost maybe and work from there with the company. Minor repairs, Major repairs this company should at least have a set-price list. ..The worker was great and efficient and did a good job on the repair but their prices are a bit costly. And yes, I did write this in their review.

The word "plumber" dates from the Roman Empire. The Latin for lead is plumbum. Roman roofs used lead in conduits and drain pipes and some were also covered with lead, lead was also used for piping and for making baths. In medieval times anyone who worked with lead was referred to as a plumber as can be seen from an extract of workmen fixing a roof in Westminster Palace and were referred to as plumbers "To Gilbert de Westminster, plumber, working about the roof of the pantry of the little hall, covering it with lead, and about various defects in the roof of the little hall". Thus a person with expertise in working with lead was first known as a Plumbarius which was later shortened to plumber.
