When my cousin from Toronto was dealing with constant power outages last winter, it got me thinking about my own sump pump's reliability during blackouts. I wanted to find a backup system that doesnt rely on electricity. Thats when I found https://drainexpress.ca/evaluating-the-efficiency-of-water-powered-sump-pumps/ . This page was super informative, explaining how water-powered sump pumps work and their benefits, especially useful in areas prone to power loss. They provide a Canadian perspective, which is great because it matches our local conditions here. I really liked the depth of the information which helped me understand the options available.
