Precautionary Measures

Make sure you have proper insurance.

Sewer backups are not automatically covered by all homeowner’s insurance policies. Check your policy to make sure you are covered for damages due to sewer backups.

Remember, the City is not an insurer. The City can only pay for damages under extremely limited circumstances set out by law.

Don’t assume you’re covered! You may need a special option for coverage. Talk to your insurance agent.

If you live downhill, install a backflow valve.

If the slab or basement under your house is lower than the nearest manhole – at the bottom of a hill, for example. The City Plumbing Code requires a back-flow valve on the line connecting your building and the sewer main.

The valve closes when water comes into it from the wrong direction.

If a clog occurs, the back-flow valve will stop the sewage from backing up into your house.

If you are downhill from the sewer main, be sure a back-flow valve has been put on your sewer line – especially if your house is in an older area of the city.

Even if your house is in a border line location, installing a backflow valve may be a good precaution. Once the valve is installed, clean it periodically to keep it working right. Talk to your plumber about the installation and cleaning or Call Customer Service.

Avoid future backups

Call the City at the first sign of a problem – before the sewer backs up. If your drains are running slow, for example, call . Someone will come and check the lines.

Dispose of grease and fats with your trash, not down the drain. Even if you run it through a garbage disposal, grease in drains can collect and harden into a plug.

Plant trees and large shrubs away from sewer lines. Roots grow toward breaks or cracks in lines. When roots get inside the pipe, they clog it.

Never connect sump pumps. French drains or other flood control systems to your sanitary sewer. It’s illegal and the debris and silt will clog your line. Call a plumber to undo illegal connections.
