Homeowner Information

WSSC Plumbing and Gasfitting Regulations (Code) require that a WSSC licensed plumber/gasfitter perform most major plumbing projects within Prince George's or Montgomery Counties. This requirement is in place to protect you the homeowner. The WSSC works to ensure that installations meet minimum Code requirements for safety, durability, and longevity. Examples of work that must be performed by a WSSC licensee are: construction of a new home; water/sewer service line repairs and replacements; interior re-pipes; all gas work such as furnace replacements and gas water heater replacements. Section 106.11 of Code for Plumbing Work by Homeowners. The best way to find a reputable plumber is by word-of-mouth. Once you have selected a plumber, he/she should provide you with their WSSC license number. To verify their license status, you may call WSSC's Licensing Office, at 301/206-8588. A few words of advice:

ALWAYS INQUIRE BEFORE YOU HIRE
GET A CONTRACT IN WRITING OR YOU MAY BE FIGHTING
MAKE THEM FINISH HALF-WAY BEFORE YOU PAY

To schedule a WSSC inspection for work performed under a short-form permit, you will need to obtain the short-form permit from the plumber, and follow the instructions on the back of the short-form permit.

Procedure for Scheduling Short-Form Inspections

  • This permit must be on the job at the time of both the installation and the inspection. /li>
  • It shall be the Master Plumber's/Gasfitter's responsibility, not the homeowner's, to ensure that work performed under this permit has been inspected by the WSSC within five (5) calendar days of installation. For the convenience of the homeowner, the homeowner may schedule the inspection his/herself. 
  • Inspections are scheduled for the next business day. To schedule your inspection call 301/206-4004 or 800/422-2063 between 8:00 am and 3:00 pm, Monday through Friday. Please have your permit in-hand when you call. View the WSSC Holidays for the current year.
  • Please alert the scheduler of any special circumstances concerning your inspection.

Long Form Permit Scheduling Instructions

The Master licensee, or his/her representative, is the only person authorized under WSSC policy to schedule inspections on a long-form permit. The policy ensures that the licensee remains informed that an inspection is being scheduled under his/her license, and ensures that each phase of work is complete prior to inspection scheduling. 

The WSSC's Interactive Voice Response System (IVRS) is available for long-form permit inspection scheduling from 7:00 am, to 7:00 pm, Monday through Friday. To use the IVRS, call 301/206-8383, or 800/422-2063. Please note, if you are scheduling an inspection on a permit which is a 6-digit number, you must precede the number with a zero (0). For example, if your permit number is 955212, you must enter the permit as 0955212 when using the IVRS.  The e-mail address for Inspection Support staff is inspectionsupport@wsscwater.com

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: 

The first call is to be made to the Chief Plumbing Inspector (or another supervisory staff member), requesting approval for the emergency inspection. 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.

Emergency Inspection Phone Numbers:
During business hours: (301) 206-8526 (or) (301) 206-8525 (Regulatory Services) 
After business hours:   (301) 206-8222  (WSSC Emergency Services)

Special Note To Homeowners:

  • The WSSC is the inspection agency for gasfitting and plumbing work in Prince George's and Montgomery Counties. This permit and inspection is for your protection and is required by Code. In accordance with Code, your plumber/gasfitter is required to provide a warranty from the date of final inspection approval as follows: One year inside buildings or above grade; and three years below grade.
  • In general, the plumber/gasfitter does not have to be present during the inspection. However, inspection staff must be escorted by the homeowner or the homeowner's representative for inside and backyard inspections. Inspectors will not enter yards or homes where dogs/animals are unattended.
  • On May 1st 0f 2007 WSSC adopted the International Plumbing and Fuel Gas Codes. Subsequently residential permits issued after that date require a testable backflow assembly for the fire sprinkler system. The assembly was tested at installation and a WSSC test tag with the date it was tested was attached. By code this backflow assembly must be tested annually. Also permits issued for sub-meters with backflow preventers for lawn irrigation systems require an annually test. It is recommended that this assembly is tested in the spring before operating the irrigation system. All testable backflow preventers must be tested annually to insure the safety of the potable drinking water in your home. For further information or assistance please contact the Cross Connection Control office at 301-206-8601.
