Emergency Inspections

Requests for an emergency gas or plumbing inspection (after-hours, weekends, holidays), will be considered only after prior request and approval by Regulatory Services supervisory staff. Examples of emergencies include: gas repairs in multi-family complexes where occupants are without heat, hot water, or cooking facilities; water service repairs in freezing weather; and repairs to deep water/sewer piping in areas where jobsite conditions pose an imminent threat to public safety.

The most common emergency occurs after an apartment fire. In this situation, the gas utility removes the gas meter to ensure safety. Prior to restoring service, all gas piping must be pressure tested in accordance with Code requirements. In addition, any major health/safety items must be brought up to Code at this time. Typical items include appliance gas cocks, deteriorated vents, and flex-connectors. Each building address requires one short form permit at time of inspection.

The procedure for requesting an emergency inspection is as follows:

This call must be made as soon as your company has been contracted to perform the work. You must provide: the job name and location; permit number; contact person and phone numbers; and the estimated time/date that the emergency inspection will be required. The permit must be on the jobsite at the time of inspection.

The second call is placed when the work is ready for inspection. The Plumbing Inspector will be dispatched with this call. As a general rule, the Plumbing Inspector will not be dispatched between the hours of 9 p.m. and 7 a.m.

Sewer and Drain Cleaner's License

Applicants may qualify for registration as a WSSC Sewer and Drain Cleaner after furnishing satisfactory proof of work experience in the sewer and drain cleaning business, under the direction of a WSSC-licensed Sewer and Drain Cleaner, Master Plumber, or Master Plumber/Gasfitter, for a minimum of 3,750 hours and two years. Proof of work experience must be submitted by written notarized statements from one or more employers (WSSC licensee of record) of the applicant, and W-2's from the employers. The applicant must also submit referral evidence from a minimum of three persons familiar with the applicant's trade qualifications and character.

Journeyman Plumber or Journeyman Plumber/Gasfitter is considered a qualified applicant in lieu of the work experience requirements. A Master Plumber or Master Plumber/Gasfitter does not need to additionally hold a Sewer and Drain Cleaner's license in order to conduct Sewer and Drain Cleaning business. Journeyman Plumbers and Sewer and Drain Cleaners who conduct sewer and drain cleaning business as the Licensee of Record must submit a certificate of insurance listing WSSC as the certificate holder. Expired insurance certificates invalidate a Sewer and Drain Cleaner's license, and must be renewed and resubmitted to WSSC in order to continue conducting sewer and drain cleaning business in the WSSD. Sewer and Drain Cleaners must renew their license every two years, and pay the associated fees approved by the Commission at time of license registration/renewal.

The following link is a list of approved cross-connections training instructors who are trained and certified to provide training to the plumbing service providers. Existing Master Plumbers and Journeyman Plumbers or candidates seeking either of these two licenses must obtain their training and certification from an approved trainer.

Initial training for first-time cross connection technicians shall be a minimum of a 32-hour course and the certification is good for three years. Individuals seeking re-certification must complete an 8 hour course, which is also good for three years.
