In towns like Peterborough, throughout Durham Region, and across the Kawarthas, spring thaws and surprise summer downpours are part of the package. That’s why a reliable sump pump isn’t just nice to have — it’s essential. But what happens when yours quits working right when you need it most?
Let’s break down the top 5 reasons sump pumps fail — and how to stop water damage before it starts.
1. Power Outages
Let’s start with the most common issue: power failure. If your sump pump relies solely on electricity and the power goes out during a storm (which is when you need it most!), it can’t do its job.
How to prevent it:
💡 Invest in a battery backup system or a water-powered backup pump. These kick in automatically when the power goes out, keeping your basement dry even during outages.
2. Stuck or Malfunctioning Float Switch
Your sump pump turns on when the water rises and triggers the float switch. But over time, this switch can get stuck or wear out—leaving your pump sitting idle while water rises.
How to prevent it:
🛠️ Test your sump pump a few times a year by pouring water into the pit and watching it cycle on and off. If it doesn’t activate, the float switch might need replacing.
3. Clogged Discharge Lines
Sump pumps work by pushing water out through a discharge line. If that line is blocked by debris, ice, or even small animals (yes, it happens!), the water has nowhere to go.
How to prevent it:
🚰 Make sure your discharge line has a clear, debris-free path. Adding a screen or protective cover can help, and consider using a freeze-resistant hose in colder months—especially important for Peterborough’s chilly springs.
4. Lack of Maintenance
Like any mechanical system, sump pumps need a little love. Without regular checkups, components can wear out or the pit can fill with sludge and sediment.
How to prevent it:
🔧 Schedule seasonal maintenance, especially before spring melt or heavy summer rains. Clean the pit, check the valves, and make sure the pump is sitting level.
5. Pump Is Too Small or Worn Out
Not all sump pumps are created equal. If your home has high water volume or your pump is old and underpowered, it may not be able to keep up.
