Why it’s important for Plumbers to be Listed in an Online Licensed Plumbers Directory.

A Licensed Plumber Directory is the index of all Licensed plumbers in a certain geographical area. The term plumber means different things to different people. The average person may consider a plumber that worker who unclogs their kitchen drain or fixes a leaky toilet. In reality, Licensed Plumbers do more than install various types of pipe through which hot and cold water run.

The plumbing industry refers to a “plumber” as a craftsman employed to provide services related to the provision of safe drinking water to and proper disposal of sanitary and storm-water wastewater. Licensed Plumbers install and repair the water, waste (sanitary and storm), drainage, and gas systems in residential, commercial and industrial structures. Essentially Licensed Plumbers are health protectors.




An unlicensed, untrained person performing plumbing work can cause contamination by a cross-connection. This can put an entire community they live in at risk of sickness and disease, not to mention potential criminal and civil proceedings. 

The plumbing trade is complex and very technical. Licensed Plumbers are held to numerous health and safety requirements that require specialized understanding that properly regulate the trade. Plumbers must be familiar with safety procedures, hazardous material precautions, along with OSHA requirements. They must review and understand construction documents and be able to read a blueprint. It requires being able to perform calculations and determine installation locations. They install piping made of various materials and must understand installation methods for water supply, waste, and venting.

The actual science of plumbing is based upon hydraulics and pneumatics. Licensing requirements are essential for Plumbing Contractors in order to uphold Public health and Safety.

Why licensing is important?

Regulated professions in the United States are licensed at the state level, and most licensed professions require some formal postsecondary education or training as a prerequisite for entry. The competent authority for recognizing professional qualifications is the appropriate state or territorial licensing authority in the jurisdiction where one intends to work.  According to NASCLA, licensing is required for any type of work involving construction at certain value limits.  

Interstate Licensure Reciprocity

Since professional licensure is regulated at the state level, it is generally necessary to obtain a separate license for each state in which one wishes to practice. In some instances, reciprocity agreements are in place to make it easier for someone who already holds a license in one state to obtain a license in another state. However, the degree to which such reciprocity exists can vary widely depending on the profession and the states involved. State licensing boards can provide detailed information on the existence of any reciprocity agreements they have with other states.

Certification versus Licensure – defining the difference

Although some states occasionally use the term “certification” to refer to licensure, the term “licensure” generally refers to an official process, administered by a state-level authority, that is required by law in order for an individual to practice his or her profession. In most instances, the term “certification” refers to a function administered by a nongovernmental organization, which is intended to further recognize professional competence based on having met the quality standards of the organization. The prevalence and relevance of certification vary by profession.  Here are the defining characteristics of Certification and Licensing:

Credential: This is an umbrella term used for a variety of programs such as licensure, certification, accreditation, and certificates. A credential is the proof of qualification, competence, or authority issued to an individual by a third party.  The third party must have a relevant or de facto authority or assumed competence to do so.

Credentialing: This process is used to establish the qualifications of professionals, organizational members, or organizations.  It is used to assess its legitimacy to meet predetermined and standardized criteria.  Organizations, processes, services, products, and Individuals, maybe credentialed.

Licensure: A governmental agency uses this process to grant time-limited permission to an individual.  This individual may engage in a given occupation after verifying that he or she has met predetermined and standardized criteria (usually education, experience, and examination).

  • Licensure ensures that the licensees have the minimal degree of competency. This competency is necessary to ensure that public health, safety, and/or welfare are protected.
  • To meet eligibility requirements, one must take and pass an assessment that covers a broad range of knowledge and skills.  A satisfactory grade will constitute the granting a license.
  • Generally, there are ongoing requirements that need to be met in order to maintain a license (CEUs, retests, physical exams, etc.).
  • In most cases, they are granted at the state level.  If an individual works in multiple jurisdictions, they must be licensed in each jurisdiction. Licensing requirements vary based on jurisdiction.
  • Professional associations do not grant licensure.   However, they play a role in licensure activities, such as advocating for the license.  They collaborate with agencies responsible for the development and administration of licensing.

The terms “licensure” and “registration” are oftentimes used interchangeably. An example of this credential would be a registered dietician or Licensed Plumbing Contractor.

Certification: This is a voluntary process by which a nongovernmental agency grants a time-limited recognition.   An individual is recognized after verifying that he or she has met predetermined and standardized criteria.

  • In order to become certified, an individual must meet eligibility requirements and pass the assessment.
  • Certification is voluntary. An individual does not need to be certified in order to engage in a given occupation. Certification has traditionally been an association activity.  A group of professionals determines the need to publicly state standards through an assessment of competence, quality, or specialized knowledge.
  • The certification assessment may cover a broad area of knowledge and skills.  This includes entry, specialty, or advanced levels.
  • Individuals who receive certificates usually have ongoing requirements, such as continuing education or retesting, to maintain the certification.
  • Certificate programs should not be confused with certification.

Plumbing, HVAC and Electrical certification programs examples are those offered by NITC STAR, ASSE, ASPE, Star HVACR Mastery, Star Pipefitting Mastery, NATE, and AVO Training. Some of these programs offer credentials for individuals, while most use a “certification” for their credential program.

Certificate:  A document serving as evidence, or as written testimony, of status, qualifications, privileges, or the truth of something.  It is acquired on a voluntary process by a person or organization.

  • Certificates are issued by an institution not authorized to grant diplomas, or to a student not qualifying for a diploma.
  • This is a one-time recognition that does not expire and does not have ongoing requirements.
  • A certificate belongs to the individual and not the organization, which is unlike certification or accreditation,

Accreditation:  a time-limited recognition or credentials to an organization by a nongovernmental entity.  It is a voluntary process and is granted after verifying that predetermined and standardized criteria are met.

  • Accreditation is generally voluntary; however, in some cases, it’s so important that it can be considered quasi-mandatory.
  • The focus of an accreditation’s assessment is one of effective, safe processes and outcomes.
  • Accreditation generally has ongoing requirements (such as applications or site visits) that must be met in order to maintain the accreditation.

Example of this for plumbing are the PHCC, ASPE, NITC.  Examples for HVAC are ACCA, NATE, HVAC Excellence, National Comfort Institute.  Electrical include NFPA, ABET, and NETA.

This searchable Licensed Plumbers directory is intended to help the public find Licensed Plumbers in their location.  It also builds public awareness about the requirements of being licensed.

Building an increased recognition on the importance of being Licensed in general and a growing recognition of the quality workmanship of Licensed Plumbing Contractor has led PHCEid to develop the online Licensed Plumbers Directory.  It’s easy to use the index of Licensed Plumbers that are qualified to perform work for the public.

The more qualified Licensed Plumbing professionals there are, the better protected our water and sanitation systems become. It is much like having more sanitary districts watching over the public water systems.  Having more qualified Licensed Plumbers ensures a higher level of public health safety.

In addition to personal benefit, a License and certification are a Plumber’s tool in two ways. To begin with, it is a way to verify the time and money invested in education and have a tangible skill to show for it. Secondly, it is a way for a plumber to know he or she is capable because they have the credentials to show they know what they are talking about.
