The Hidden Risks of No Backup Pump

  • Power Loss: Municipal outages during storms render traditional pumps useless
  • Mechanical Failure: Even good pumps can clog or break unexpectedly
  • Flood Damage: Basement flooding causes structural harm, mould growth, musty odours and ruined belongings Ignoring these risks can cost far more than the installation of a modest backup system

How Battery Backup Sump Pumps Work—And Why You Need One

Battery backup sump pumps act as your home’s second line of defence. When your main sump pump fails—whether due to a power outage, mechanical failure, or overwhelmed system—a battery-powered backup automatically kicks in. It quietly moves water out of your basement, even when the lights go out. 

Here’s why it matters in Toronto:

Power failures often hit when storms do. Without backup, water quickly accumulates.

Water seeping through cracks in your basement walls or floors is a clear indication of a problem with your foundation.

Whether you’re at work, on vacation, or simply asleep—your home remains protected.

These systems are especially critical if your basement houses valuable items, finished living space, or home offices. For many homeowners in the GTA, a backup sump pump isn’t a luxury—it’s an essential safeguard.

Going thru some old files for my rental property, I discovered a contract which Gavin had signed in Jan 2007 to repair a foundation leak in my basement. This leak had been 'fixed' multiple times by others using epoxy. Gavin explained that the only sure way to fix the leak once and for all, was to dig down to the foundation from the outside to seal the cracks, plus provide a waterproof barrier against the wall. The work was done excellently and came with a 15 year warranty. It has been 19 years and no leaks have occurred. If you want a basement leak fixed right the first time, then contact GJ MacRae Foundation Repair. Highly recommended.

Today Gavin MacRae did thorough inspection of 2 sump pumps & battery backups which he installed in 2018 - both systems still performing well. Prior to 2018 MacRae Foundation did extensive foundation/waterproofing for us - quality of workmanship excellent. Without hesitation, strongly recommend MacRae Foundation.

We had a difficult project requiring excavation, waterproofing, and installing a sump pump on a 130 year old house, and GJ MacRae did an amazing and very thorough job. They went above and beyond to repair the foundation that had started to deteriorate as well. Very professional and high quality work. I'd definitely recommend this company!

Great job. Fast response to inquiries, job done fast and professionally. Put everything around the area back in place to the point where you wouldn't even know any work was done afterwards. Would 100% recommend calling them if you have a foundation repair issue.

Let's just say that there aren't many companies of this calibre around these days. We've been dealing with GJ MacRae for the last seven years for everything sump pump related. Seven years ago the fine folks at GJ MacRae came in and replaced our existing sump with a modern unit complete with a marine battery backup and secondary pump. We have a ton of ground water around here and when it rains our sump fires non stop. Everything has been perfect and when it came time to service our system seven years in, GJ MacRae was all over it. Exceptional service, communication price and product. It's rare to see all 3 these days. Thanks for everything Gavin.

Frequently Asked Questions

With AGM marine batteries, expect 3–5 years of reliable backup.

DIY is possible, but a professional installation ensures proper check‑valves, discharge routing, safe wiring, and code compliance.

Our approach includes backup alarms and routine maintenance, plus we offer combined systems to cover both power loss and pump malfunction.

Yes. While they require less maintenance than primary pumps, it’s important to test the system every few months, check battery charge levels, and replace the battery every 3 to 5 years to ensure reliable operation during emergencies.

If your home has experienced power outages during storms, or if your basement contains finished spaces or valuable items, a backup system is highly recommended. Even a reliable primary pump can fail due to power loss or clogging—having a battery backup offers essential protection.
