Building sewer · West Haven

Main sewer line clearing

When more than one fixture backs up — or water appears at the lowest drain in the house — the obstruction is likely in the line that carries everything out of the building.

Active sewage backup

Stop using water in the house, keep people and pets away from the affected area, and avoid contact with the wastewater. Don't open a cleanout under pressure; leave it for our team.

Signs of a main-line problem

  • Two or more fixtures on different floors drain slowly at the same time.
  • Water rises in a basement floor drain or shower when the washing machine empties.
  • Toilets gurgle when a sink drains; flushing pushes water into the tub.
  • Sewage odour near the lowest drain or the cleanout.

The private building sewer in West Haven

West Haven's sewer code defines the building sewer as the pipe running from the building drain to the public sewer. The city does not maintain it; maintaining the connected lateral is the property owner's responsibility, and the code assigns owners the expense of installing, maintaining and repairing it (Article I, Article II).

That definition tells you who looks after which pipe. It does not tell you where a particular blockage is. Only an assessment on site can locate it.

Private building sewer and public sewer, conceptualA house drain leads to a cleanout, then the building sewer runs to the property line and connects to the public sewer main under the street.

Conceptual illustration, not to scale. Under West Haven's sewer code the building sewer from the building drain to the public sewer is privately maintained. The actual location of any blockage needs on-site assessment.

Cleanout access

A cleanout is a capped opening that lets our team reach the line without pulling a toilet. In many houses it's in the basement where the drain leaves the wall; in others it's outside near the foundation, or it may be buried or missing. Before you call, look for it if you can do so safely, and tell us where it is. Lack of access can change the method and the time needed.

Clearing is not repair

Clearing restores flow by cutting through or flushing out what is blocking the line. If roots have grown through a joint, or a section has collapsed or sagged, clearing may only buy time. Repairing or replacing the building sewer is a separate scope, can involve excavation and restoration, and in West Haven may need sewer permits and inspection under the city code. A camera inspection can help our team show you which situation you're in.

If you think it's the public sewer

If you see sewage at a street manhole, or neighbours are reporting backups at the same time, contact the city. West Haven Public Works lists 203-937-3637 for sanitary-sewer information, questions or problems, with 24/7 response. Calling the city is a report, not a finding that the city is responsible for your property's line.

Questions

Will one visit fix it?
Often a clearing restores flow. Whether the problem returns depends on what caused it — which is why repeat backups usually call for an inspection.
Does clearing need a city permit?
Routine clearing of an existing line generally doesn't, but alterations, connection work and repairs to the building sewer can. Ask our team and check with the city for your situation.
Water comes up only during heavy rain — is that this?
Possibly not. Rain-associated water may be a storm drainage issue. West Haven's code prohibits sending stormwater or roof runoff into the sanitary sewer (Article III). Describe exactly when it happens when you call.
