Although plumbers, pipefitters, and steamfitters perform three distinct and specialized roles, their duties are often similar. For example, they all install pipes and fittings that carry water, steam, air, or other liquids or gases. They determine the necessary materials for a job, connect pipes, and perform pressure tests to ensure that a pipe system is airtight and watertight. Their tools include drills, saws, welding torches, and wrenches.
The introduction of the first water-retaining traps or seals in the 1850s, and the common use of "U"-shaped traps in the 1870s, were major steps forward. The design of the trap ensured that enough water remained in it to effectively block the passage of sewer gas back through the plumbing fixtures. During the 1870s vent pipes were introduced. They not only carried sewer gas out of the system, but also broke the suction created by movement of liquid in the pipes and eliminated the possibility of siphoning water that sealed the traps.
“Don’t assume that every Mr. Fix-it advertising his services in the local Pennysaver or on Craigslist is a licensed plumber,” says one New York plumber. There is no national standard for issuing licenses. Some plumbers are licensed by the state, others by the counties they work in. Check with your local city hall or chamber of commerce. They should be able to direct you to the appropriate source for a list of licensed plumbers in your area.

I was disappointed with the pressure of a tub and shower that were plumbed with 1/2 supply lines (2nd floor). Could be low pressure from the street, but I want to replace with 5/8. Plus, I'd like to have 2 back to back showers, one inside and one outside. So, I had intended to bring a 1 supply to both, then branch up to valves and shower head with 5/8. Finally, I thought pressure from the street was typically 55 to 70 psi and I am concerned if pvc can take that.Any thoughts?
