Sump Pump Failure in Markville — How a Battery Backup Prevented Disaster

Last August, a freak thunderstorm knocked out power across Markville for almost six hours. Sump pumps across the neighbourhood failed silently. Basements flooded.

One didn't. The Khan family had let us install a battery backup sump pump six months earlier. Their primary pump went dark at 2:14am. The backup kicked in within seconds and ran for four straight hours until the grid came back.

Why every Markham home with a sump pit needs a backup

Markham gets serious storms. Storms knock out power. Power outages stop your sump pump. A primary pump alone is a single point of failure — and that single point fails exactly when you need it most.

A modern battery backup sits beside your primary pump, monitors it constantly, and takes over the moment AC power drops or the primary fails. Most can run 6–12 hours on a single charge depending on cycling.

What we install

We use sealed deep-cycle batteries paired with a high-output backup pump rated to move at least 2000 GPH. Total install time: about 3 hours. Workmanship warranty on workmanship.
