Home flooding is a serious problem, particularly in the Greater Toronto Area. Many homes in Mississauga and Toronto have experienced major flooding issues resulting in millions of dollars of damage. It is important that flood prevention be taken seriously to correct the most common problems that result in home flooding. We managed to speak with a Toronto, ON plumber in the area and able to get an explanation of what areas homeowners need to pay attention to concerning preventing floods.
A backwater valve is one of the most important devices that all Greater Toronto Area homes should have installed. It is a very simple valve and installation does not require extensive excavation.
The backwater valve connects to the homes main drain and allows for the travel of drain contents to the municipal storm sewer. Storm sewers being overwhelmed by rainwater have caused a common reason for basement flooding in Greater Toronto Area. This rainwater backs up into the homes basement causing extensive flooding. The backwater valve is a simple device that closes once the flow of water is backing up into the home, thus preventing basement flooding from occurring.
Many homes in GTA now have these valves installed, but many still do not, it is incredibly important that homeowners install these valves to prevent flooding from occurring.
A sump pump is also a very important device that many homes require particularly in the GTA area. Essentially, they bail out water that has built up near the foundation of a home preventing flooding from occurring as a result of a rising water table.
The method of installation is fairly simple. A sump pit is dug out into the basement of a home. Often a weeping tile system is setup next to the homes foundation, essentially this is a large pipe with holes that allows water to collect inside of it, and this water is then diverted to the sump pit. Once water accumulates in the sump pit, it begins to fill up. Often a sump pump has a special floating activation lever. As the water level rises, it eventually triggers the sump pump, which then pumps water out of the sump pit.
Quite a number of homes in the GTA have sump pumps installed, though many homes still do not have a proper sump pump setup. It is a device many homes should have be installed that are prone to flooding due to a high water table.
