I have 14 years experience in the plumbing trade, including my 4 year apprenticeship. I operate under my contractor's licence having completed the required TAFE studies and in addition I am about to complete my Certificate 4 in plumbing. This certificate will enable me to plan, size and layout plumbing in buildings up to 6 stories. Only a limited number of plumbers have completed this course and have this certificate in South Australia.
