Pittsburgh Plumbing: Licensing, Permits & Water

Article XV builds the ladder countywide: an apprentice card that expires every September, a journeyman credential earned with five hundred seventy-six classroom hours plus four years under a registered master and an exam offered twice a year, and a master credential after two further years and its own exam, with renewals falling due on the holder's birthday. Only a registered master plumber may run a plumbing business anywhere in the county, Pittsburgh included, and Pennsylvania adds no state plumbing license above any of it. The health-department pedigree also writes the landlord rule: rental-unit plumbing belongs to a master plumber, while owners may work only on the homes they actually live in.

• Authority. Allegheny County Health Department (ACHD) Plumbing Program, the countywide authority whose credentials cover Pittsburgh; Pennsylvania issues no state plumbing license
• Structure. Three ACHD credentials under Article XV (2022): an Apprentice card issued on enrollment in an accredited apprenticeship, valid only working alongside a journeyman and expiring each September 30; Journeyman, earned with five hundred seventy-six classroom hours plus four years under a registered master and an exam offered twice a year; and Master, after two further years as a journeyman and its own exam. Renewals fall due on the holder's birth date, and only a registered master plumber may engage in the business of plumbing
• Worth knowing. Pittsburgh is among the few big American cities whose plumbing credentials come from a county health department rather than a buildings office. Allegheny County also gives landlords a rule of their own: rental-unit plumbing work requires a master plumber, and an owner may do plumbing personally only in the residence they occupy.

Every job starts with a plan: the county reviews and approves a plumbing plan (fixtures, water service and building sewer, locations and materials drawn out) before any work begins, then inspects as the work proceeds and once more at the end. The homeowner exception is written tightly: a bona fide owner living in an existing single-family dwelling may take the permit personally, on the condition of buying every material and performing every hour of labor, with the fees and open-wall inspections still applying in full. Roughly fourteen thousand plans move through the program in a year, and one modern rule stands out: a lead water service line now comes out whole. Partial replacements are no longer permitted, and the division inspects the full swap.

• Permit office. Allegheny County Health Department Plumbing Program on Noblestown Road, with filings through the county's online portal or in person; the city's own Permits, Licenses & Inspections bureau states plainly that plumbing permits belong to the county
• Homeowner rule. Article XV's exception is narrow: a bona fide owner presently occupying an existing single-family dwelling may hold the permit personally, on the condition of purchasing all material and performing all labor. Plan review, fees and inspections still apply in full, and rental property never qualifies
• Process. A plumbing plan must be approved before any work starts, with fixtures, water service and building sewer drawn out with materials; inspections then follow as work proceeds, with a final on every permit. Partial lead water service line replacements are no longer permitted at all, only full replacement with approved materials

Pittsburgh Water has never printed a hardness number in an annual report (the utility's FAQ settles for an adjective, moderately hard), so the figure above comes from the state's own drinking-water database: one hundred ten samples across the system in 2016 measured calcium hardness averaging fifty-nine point nine milligrams per liter as calcium carbonate, in a range of forty-four to seventy-four. Calcium alone understates the whole, since magnesium rides along in any river supply, which is why the utility's adjective rather than the bare number sets the band shown here. The supply is the Allegheny River treated at Aspinwall, with a purchased share from Monongahela River plants serving the city's south, and since 2019 the system has dosed orthophosphate for corrosion control, so the chemistry in Pittsburgh's pipes is actively managed, not raw.

• Utility. Pittsburgh Water (formerly the Pittsburgh Water and Sewer Authority)
• Supply source. The Allegheny River, treated at the Aspinwall complex, with a share purchased from Pennsylvania American Water's Monongahela River plants for parts of the city's south
• Hardness. 60 mg/L (≈3.5 gpg), moderately hard; state calcium sampling (band: utility's wording), 2016

Utility information: www.pgh2o.com. The hardness figure is the same record shown on the Pennsylvania page.

• Drain Cleaning
• Water Heater Repair

  State sampling puts Pittsburgh calcium hardness near sixty as CaCO3, moderately hard by the utility's own wording, so scale works slowly here compared with hard-water country.

• Sewer Line Repair

  The building sewer sits on the ACHD plumbing plan itself, with county review before excavation and inspections as work proceeds, and lead water services now come out whole, never in part.
