Mandatory Downspout Disconnection
Do-it-yourself instructions
What you’ll need:
- Hacksaw
- Tape measure
- Hammer
- Screwdriver
- Drill
- Pliers
- Metal file
- Sheet metal screws
- Wingnut test plug and concrete (optional)
- Rubber cap or PVC cap
- Downspout elbow
- Splash pads
- Ladder
- Downspout pipe extension
- Brackets to secure the downspout to the building
- Protective equipment (gloves, safety glasses, etc.)
Step one:
Measure 23cm (9”) from where the downspout enters the sewer connection.
Step two:
Cut the downspout with a fine blade hacksaw. Make sure to remove the cut piece and do not drop it down the drain. Use a metal file to remove the rough edge of the downspout.
Step three:
Be sure to cap the sewer standpipe -- the open pipe remaining when the downspout is disconnected. This prevents water from going in. It also stops animals from falling into the opening, getting trapped, and having to be rescued. You can use a simple rubber cap secured by a hose clamp, PVC cap or a wingnut test plug and concrete if available cap sizes don't fit.
Step four:
Insert the downspout into the elbow (if you put the elbow into the downspout, it will leak). You may need to crimp the end of the downspout with a pair of pliers to get a good fit.
Step five:
Attach a downspout pipe extension to carry water away from the house and foundation. You can use a hacksaw to cut the extension to the desired length. Be sure to insert the elbow into the extension to prevent leaks. Drill a hole on either side and secure the elbow and extension with sheet metal screws. To prevent erosion where the water drains, you can place a splash pad at the end of the downspout extension.
Please note: When redirecting the rain water from the disconnected downspout, water should flow onto your ground or run off safely. It is important to ensure that:
- Water flows away from your foundation walls
- Water does not negatively impact your neighbour's property
- Water does not flow directly onto a City sidewalk
