Plumbing requires some study on your part after perhaps deciding on doing it as a form of living. If you happen to be someone who has basic technical skills then you can actually do some plumbing on your own.
Residential, commercial, institutional, industrial, and service are the different basic areas of plumbing. Formal learning on plumbing is structured within a four year span of two months discussion in class and the rest on experiential learning. It is acceptable for plumbing students to extend in school but overstaying would lead to expulsion. You can stop for one semester or two and get extended until your fifth year of training. You might be asked to start from the beginning of the plumbing course when you go beyond the expected number of years to complete it.
The type of tools you will be using depends on the type of plumbing work you will do. If that is the case, only prepare the tools that will be used for the plumbing job you are in.
As a plumber it is your responsibility to repair and replace sinks & toilets, repair and replace faucets, clean the drains and repair leaks. In learning these plumbing services, you have to do a lot of practice to master them. Excellence on those skills becomes a reality as you overlearn them. The following tools are expected to be used by a plumber: screwdriver, drywall screw, Allen wrench, tape measure, pipe cutter, crimper, torch, pex cutter, hacksaw, adjustable pliers, basin wrench, adjustable wrench, pipe wrench, knife, and hammer. The list of tools gets you covered on each plumbing job. Some specialized plumbing jobs requires a jig saw, cast iron cutters, drill, and a reciprocating saw. The simpler plumbing jobs would need only the hand tools. More complicated plumbing jobs would need more of the power tools. Sources for the plumbing tools you need are the rental outlets and the local hardware stores. A typical plumbing job done by a non-expert would take more time as compared to an expert. A plumbing job will eat a lot of your time when you fail to prepare every material and tool needed for the job. To save time, get started by checking first the tools and materials that you need at the store and buying or renting them for the plumbing job. When the plumbing job is too much for you, another plumber can help you but tell the plumber to bring everything that he or she needs so that the job would be finished faster if it can be helped. And just to be fair with the other plumber, talk to him or her about the job that needs to be done because you will know the length of time for it to be completed.
