After a friend had issues with her sump pump during a particularly wet spring, it got me thinking about checking our own system before the next rainy season hits. I wasn’t sure about the specifics, particularly the float switch, so I went online and discovered https://drainexpress.ca/how-do....es-a-sump-pump-float . The site breaks down everything you need to know about how these switches work and how to maintain them, specifically catering to Canadian climates and conditions. It's quite detailed, providing practical advice that can save a lot of hassle down the road.
