Lastly and perhaps most importantly is the fact that almost every plumber needs good social and interpersonal skills
. Unless a plumber works on a single contract or project (which is seldom the case) they will have to interact with many different people of various creeds and personality types. In countries like South Africa the importance of this is even more emphasised by the diverse number of cultures races and most importantly languages. With regard to language, a plumber not only has to be able to successfully communicate with clients, but also with staff since there is often a communication gap within the workforce itself.
