WHY REGISTER WITH THE PIRB:
Many people may claim to be plumbers but they are not competent or accredited properly which poses a risk to the consumer, the environment and the plumbing industry. Registration with the PIRB affords you the opportunity to be recognised in the plumbing industry and by the consumers as qualified and competent because certain criteria would have had to be met before you are allowed to practice as a plumber.
SANS 10254:2017 STATES THE FOLLOWING
Edition 4.1
4.1.1.3 The installation of storage water heaters shall comply with the relevant national legislation (see foreword).
4.1.1.4 On completion of the installation, a certificate of compliance from the professional body for plumbers registered in terms of the relevant national legislation, shall be issued to the owner of the installation or to the body requiring such a certificate.
Essentially this means that as a professional expert and a Licensed Qualified Plumber, it is in the interest of your professionalism to issue a PIRB Certificate of Compliance, on ALL geyser installations/repairs that are undertaken by yourself or under your adequate supervision.
It is illegal for any person who works on plumbing installation if he/she is not a qualified plumber or not working under the adequate supervision of a qualified plumber. Registered persons under the category of qualified plumbers are qualified plumbers and may carry out plumbing works and may supervise non-qualified plumbers or plumbing learners, however they will not be allowed to purchase or issue Plumbing Certificate Compliance for plumbing installations.
