Drains & sewer services in Philadelphia
Drain cleaning in Philadelphia
UrgentIf one fixture is slow, the clog is usually in that fixture's branch line. If several drains back up at once, or the basement floor drain fills when you run the washer, the main sewer line is blocked and needs a larger cable or a jetter.
Hydro jetting
Hydro jetting cleans the full width of a drain pipe with high-pressure water, washing out grease, scale and fine roots that a cable only punches a hole through. It works best on sound pipe and is usually done after a camera inspection confirms the pipe can take it.
Sewer camera inspection in Philadelphia
A sewer camera inspection runs a waterproof camera through the line from your house to the city main and records what it finds: roots, cracks, sags, offset joints or collapsed pipe. It's the best way to decide between cleaning, spot repair and replacement.
Sewer line repair in Philadelphia
UrgentA damaged sewer line can be fixed with a spot repair, a trenchless liner, pipe bursting or an open-trench replacement. Which one fits depends on what the camera shows, how deep the pipe is, and what's on top of it, such as a driveway, trees or landscaping.
Local conditions
Drains & sewer in Philadelphia: what's different
Philadelphia property owners are responsible for their sewer laterals, and repairs often involve the street. Older combined sewers can back up into rowhouse basements during heavy rain, even with the Water Department's Green City, Clean Waters stormwater program.
Some older rowhouses share sewer lines with neighbors, which complicates repairs and requires coordination between owners. Permits come from the Department of Licenses and Inspections.
