Leaks, pipes & freezing in Pittsburgh, PA

Pipe problems range from a burst line that needs the water shut off right now to slow pinhole leaks that show up as a high water bill. A licensed plumber finds where the water is escaping, repairs or replaces that section, and tells you whether the rest of the piping is likely to follow.

Leaks, pipes & freezing services in Pittsburgh

Local conditions

Leaks, pipes & freezing in Pittsburgh: what's different

Many century-old Pittsburgh homes have long, aging water service lines running up steep yards. Many have had lead service lines, which the utility has been replacing.

Freeze-thaw cycles on shaded north-facing slopes split exterior pipes and outdoor faucets.

Leak detection on long hillside service lines is more involved, and repairs often need digging on steep yards. Insulating exterior-wall pipes and outdoor faucets prevents most freeze damage.

Pittsburgh Water has also been replacing lead service lines in older neighborhoods, which is worth checking during any repair.

Pittsburgh housing and plumbing

Hillside homes from the early 1900s typically have basements, cast-iron drains, clay laterals and some galvanized supply.

Other Pittsburgh conditions that affect plumbing

  • Hillside sewer laterals: Steep lots and old clay laterals lead to cracked, root-filled lines.
  • Freeze and thaw: Repeated winter freeze-thaw cycles split exterior-wall pipes and outdoor faucets.
  • Lead service lines: Many older homes have had or still have lead service lines, which the utility has been replacing.
  • Three rivers and steep valleys: Pittsburgh's rivers and steep valleys mean many homes sit on slopes, and runoff during heavy rain can overwhelm older combined sewers.

Leaks, pipes & freezing questions in Pittsburgh

Is my Pittsburgh water service line lead?

Many older homes had lead lines. Pittsburgh Water has been replacing them; check with the utility.

Should I turn off the water if a pipe bursts?

Yes. Close the main shutoff valve first, then open a faucet on the lowest floor to drain the lines. If water is near outlets or the electrical panel, keep clear and switch off power only if you can reach the panel safely.
