Plumbers must demonstrate their competence as installers of plumbing systems to an official executing board prior to being issued a license. A plumbing code which is technically perfect is valueless if its provisions are not observed and enforced. The issuance of a license by a community specifies that the holder is qualified both theoretically and practically and that their technical knowledge is sufficient to maintain the standards of the code.
Is licensing intended to prevent anyone but a plumber from doing sanitation work? NO… Licensing prohibits the irresponsible, incapable person from endangering the health of your family, neighbours, and community. Any person may do the work who has sufficient knowledge to do it in a safe manner, so long as the Rules and Regulations of the plumbing and sanitation code are observed. However, those wishing to do such work must demonstrate their ability by taking out a license and passing an examination.
Done improperly this work would probably need to be rectified at the time the property changed hands which means paying twice for the same work. Additionally, licensed plumbing professionals are held to a certain standard of accountability – meaning they must perform their work correctly or risk being liable for accidents, damages, illnesses, etc. caused by improperly performed jobs – and must often hold some form of bonding or insurance that can help to protect you in the event of something happening.
So, while that small bathroom remodel might seem like a great, inexpensive DIY project, it is probably wisest to spend a little more and make sure a licensed plumbing contractor performs the work
