Why is a NJ Master Plumbing License Important?

Properly installed & serviced plumbing is vital to both health and safety. Improperly installed or maintained plumbing can cause health issues including virus, disease and death. A faulty installation of a water softener can create a cross contamination between your sewer and drinking water, a faulty installed water heater can explode or allow carbon monoxide to enter your home. Therefore Plumbing Services in the State New Jersey must be performed by a NJ Licensed Master Plumber. Plumbing shall be performed by a master plumber, an authorized plumbing contractor, or by employees working under the supervision of a master plumber as permitted by N.J.S.A. 45:14C-1 et seq. and N.J.A.C. 13:32-3.3.

The following shall only be performed by NJ Master Plumbers:

• Performing of plumbing work, including minor work and ordinary repairs even though a permit is not required;
• Installation and service of storm, sanitary, and water piping to the final point of connection within three feet of the exterior of a building or structure located on private property;
• Installation of the water service and backflow preventer for fire suppression systems and water sprinkler systems;
• Plumbing work performed at a place of business by employees of that business on property owned by the business;
• Disconnection and sealing of water and sewer lines;
• Installation and service of all direct and indirect drain piping
  associated with mechanical equipment that is connected to a sewer system;


• Installation and completion of plumbing, at no cost, notwithstanding that
  the property is owned by a nonprofit organization;
