Floodproofing Devices to prevent basement flooding
If your home drainage system or the neighbourhood’s drainage system overloads, you may still be able to prevent rain water and sewage from backing up into your basement by installing one or more floodproofing devices, such as sump pumps or back flow valves. Each installation is unique and some devices (back flow valves) may require a plumbing permit. Check with your municipal office or a qualified plumber before you proceed with any installation.
Sump Pit Drainage System
A sump pit drainage system includes a sump pit, a sump pump, and a discharge pipe. The sump pit, set into the basement floor, collects water from the weeping tiles around your basement. The pump pushes the water outside your house through the discharge pipe.
Place your sump pump discharge pipe so that it:
- · Drains somewhere onto your property where water can be absorbed, such as your lawn or flower bed; and
- · Does not direct water onto neighbouring properties, lanes, sidewalks, or streets.
Sump Pit
- · Clean the pit each year after freeze-up. Weeping tile drainage may carry small amounts of soil, sand and debris into the pit from around your basement foundation.
- · Some water may remain in the pit and cause a musty smell if it sits for a long time. If so, you can flush the pit by adding fresh water until the pump removes the stale water.
Sump Pump
- · Check and test your pump each spring before the rainy season begins, and before you leave your house for a long time. Pour water into the pit to trigger the pump to operate.
- · Remove and thoroughly clean the pump at least once a year. Disconnect the pump from the power source before you handle or clean it.
- · Check the pit every so often to ensure it is free of debris. Most pumps have a screen that covers the water intake. You must keep this screen clean.
Sump Pump Discharge Pipe
- · Check the place where the discharge pipe leaves the house. If the pipe is discharging right against the basement wall, the water will drain down into the weeping tiles and continue to recycle through the system.
- · Check the discharge point regularly to make sure that nothing is blocking the flow.
- · If your pump runs frequently in the winter, and the resulting ice is causing hazardous conditions on the lawn and sidewalks, call your municipal office.
