Downspout disconnection

Downspouts that are connected to the sanitary sewer system are in conflict of Region of Peel Bylaw 53-2010 and should be disconnected.

A downspout is a pipe that carries rainwater from a roof to ground level or into the ground or sewer system.

Capping prevents stormwater from entering the system after downspout disconnection but also is a safety measure to ensure debris and small animals do not enter the opening.

Standpipes can be constructed of plastic or clay and will have different diameters, which will be specific to your property.

Caps and plugs come in a variety of styles and sizes which are available at many hardware stores or plumbing supply stores. Measure the diameter of your standpipes before visiting the store to purchase caps or plugs. Property owners can use:
