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; 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). WPC has subsequently appointed a representative to the World Health Organization to take forward various projects related to Health Aspects of Plumbing.
Having the right tools can mean the difference between a quick project and a complete mess. Fortunately, you won't need too much to handle the projects here and what you will need is pretty inexpensive (certainly less expensive than hiring a plumber). You can get everything on this list for about $100, and you won't need it all unless you're doing all the projects. Where I live, that's about the cost of hiring a plumber for an hour.
Let's start with the easiest possible project: Installing a new shower head is as simple as it gets. Typically, all you have to do is unscrew the old shower head from the shower arm (the pipe coming out of the wall), clean off the threads on the shower arm and wrap a bit of Teflon tape around it, then screw on the new shower head. It's really that simple (and if you don't believe me, check out the video above from Dummies.com). Do read the installation instructions on the shower head you buy, though. Some are designed not to require Teflon tape and can actually leak if you use it.
Todd did an amazing job, and fixed a problem that could of been devastating. Replacing a leaking water heater and also a replacing a failing, leaking main shut of valve. The possibility of major flooding was a real danger It was a 12 unit townhome which made the job even trickier, as water had to be shut off to the entire building while he fixed the valve. Todd, replaced them quickly and expertly, without a hitch. Plumbing repairs are never fun for a homeowner, but these people (especially Todd) do great work. It is definitely a weight lifted off my chest.
When a person has a blockage in their sewage system they often try to fix it themselves by adding an acid or a base such as Drano in an attempt to dissolve or dislodge the problem. These chemicals can get into the plumbers eyes when the sewage is splashed during the repair. The plumbers skin during the repair does come into contact with the sewage water. The owner of the toilet might not report to the plumber they have already tried Drano a highly caustic base .
