Plumbing help in Park Ridge

House sewer connection to a combined street sewer, with a backwater valveCross-section: a house with a basement floor drain connects through a private sewer lateral to a combined sewer under the street. A backwater valve on the lateral closes when water flows backward from the street sewer.

Diagram How a backwater valve protects a basement drain connected to a combined sewer.
  1. Basement floor drain — the lowest opening, so usually the first place sewer water appears.
  2. Private sewer lateral (building sewer) — typically the owner’s responsibility.
  3. Backwater valve — a flap that is meant to close when flow reverses; needs an access cover for cleaning and inspection.
  4. Combined street sewer — during heavy rain it can fill and back up toward buildings (MWRD).

Local programs

A City of Park Ridge public works presentation explains that the city’s older sewers are largely combined storm and sanitary lines that can be overwhelmed in intense storms, and lists check valves and overhead sewers as the main homeowner measures against sewer backup.
