Cory was out here and did fantastic work. He was very fast and efficient and was upfront about all pricing. Very high quality work, super knowledgeable and showed us/ explained everything to us before he did it so we had an idea of what was going on. Really friendly guy, 4/5 because he didnt plug the coffee makers back in >:( Just kidding, in all seriousness he gets 5/5 and I would recommend Deans to anyone and everyone.

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.
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. 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. Roman lead pipe inscriptions provided information on the owner to prevent water theft.
