Most of the time, the sump pump and drainage system in your basement already prevents any water from entering your home. Water is naturally trying to go down through the pipes, and into the ground outside your home. If a clog or blockage occurs, then the sump pump goes into action in order to push the water out of your basement.
Some homeowners in Newmarket decide to add a second sump pump into their existing basement system in order to remove additional water from their property that naturally accumulates during heavy rains or snow melts. It’s a rational and justified backup, but it’s not always necessary. The only downside of this approach is that some plumbers may use this as a loophole in order to remove water from your basement without proper inspection.
