Professional Home Inspections in Wheaton, Illinois

Why can a basement back up when sewers are separate?

Wheaton has separate sanitary and storm sewers, but rainwater can still enter sanitary piping. The City identifies direct connections, such as improperly connected drains, and infiltration through deteriorated pipes as ways unwanted water can overload the sanitary system during heavy rain.

Foundation footing drains collect water around the base of a foundation. Where connected to a sanitary sewer, that drainage adds flow to a system intended for wastewater. Footing-tile disconnection addresses that connection; it is different from repairing foundation walls or installing protective basement plumbing.

Buyers should ask about previous backups, the basement's plumbing arrangement and any documented service-line or drainage work. Request pump maintenance information and records showing where foundation drainage discharges. Dunsing reviews accessible components, with an optional sewer scope for accessible interior pipe conditions. The City's program information is a useful resource for further questions; current eligibility must be confirmed directly with the City.

• Request backup history and footing-drain work records.
• Confirm accessible pump equipment and its maintenance needs.
