Who pays: insurance, protection plans and responsibility

Three questions decide who pays for a sewer problem — which section is yours, what damage is covered, and what the pipe repair is covered by.

The short answer

In most cities the homeowner is responsible for the sewer lateral all the way to the public main. A standard homeowners policy covers neither the pipe repair nor backup damage. Water backup coverage pays for damage inside; service line coverage or a protection plan pays to repair the pipe — usually up to about $10,000.

Which cover pays for what

Cleanup and pipe repair are paid for by different things, and the section under the street depends on your city. This is the map to check your own situation against.

Cleanup and repair are paid for by different things. Backup cover pays for damage inside; only a service-line add-on or a protection plan pays to fix the pipe itself, up to a cap. Whether the section under the street is covered depends on the policy and your city.

The order to check things in

  1. Find your city's rule for where owner responsibility ends.
  2. Check your homeowners policy for water backup and service line endorsements.
  3. Only then compare a utility-branded protection plan — against the add-on, and against the section your city makes yours.

The most common expensive mistakes

Almost every painful surprise with sewer costs comes from one of a handful of assumptions, and none of them costs anything to check in advance.

  • Assuming the city owns the pipe under the street. In most places it belongs to the homeowner.
  • Assuming homeowners insurance covers a sewer backup. It needs a water backup endorsement bought beforehand.
  • Buying a protection plan after a camera has found a problem. Known problems are excluded.
  • Paying for a protection plan and an insurance add-on that cover the same section of pipe.
  • Waiting to report a backup. Late notice is one of the most common reasons a claim is refused.
  • Throwing out damaged belongings before the adjuster has seen them or photographs exist.
