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".[34] 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.[35] 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.[35]
 CON'T FROM COMMENTS EARLIER.  However,  the  installation took less than 3/4/ hour and was a basic regulator with no other function.  Looking up the price afterwards, invoice did not list type or price, it appears that it would have cost me around $60 for the regulator and another $15 or so for the additional supplies necessary to install it and it was really a rather simple job with easy access.    Given that, it seems that $300 for less that  an hours worth of on site work,  company says it does not include commute time in its prices, is a little high.  While flat rate quotes are nice, they must take into consideration situations where the work load differs depending on the circumstances.  Therefore, unless you are at the upper end of the harder work needed than the average job. it can be argued that my estimated price of $300 for labor was more than a little high.  Maybe I am wrong since I have not used their services for years and  am not knowledgeable of the costs of equipment and professional labor today.  
I called BL Plumbing when a small leak started coming out of my shower. They responded quickly and Billy arrived in the afternoon. He diagnosed the problem and proposed a solution including cost. I approved and he went straight to work. Within the hour, the problem was resolved. Billy recommended work that was needed to reduce water pressure for the entire house. I approved the work including cost and Billy had that problem fixed quickly and efficiently. A small leak in the pipe below the shower led to a much needed home improvement. As we finished, Billy and I discussed potential future work and issues regarding maintenance concerning the overall projects completed that day. The entire process was a very positive experience.

We've only been in our home a few months and I noticed that they had a Dean's sticker on the furnace with a service line so I thought I would give them a try...I'm so glad I did! Ray R. came out to our house right away the next morning and he was awesome! He was super friendly and knowledgeable and he was great at talking me through what he was checking and doing. As a first time homeowner I was extremely appreciative of all of the knowledge he was able to pass along about our specific unit and all heating and cooling in general.
Kevin was very professional and personable in his interactions with us and his explanations of the cause and possible problems were right on! He had a young woman working with him who is his apprentice and she was a delightful individual as well. Both my wife and I are retired educators, and we were impressed with Kevin's patience and ability to convey what information she needed in order to perform her tasks in a satisfactory way.read more

Journeyman plumber: Once the requirements of an apprenticeship are fulfilled, plumbers can apply for a journeyman license. Many workers in the plumbing industry are journeymen. Obtaining a journeyman's license requires a fee and the successful passing of an exam. Licenses vary by state, although not all areas require journeymen to be licensed. Instead, the amount of work they are able to perform is limited.
