If your sump pump seems like it never shuts off, especially during a wet Spokane Valley spring or after heavy rain in Post Falls and Liberty Lake, it could mean your system is working overtime or there’s a problem that needs attention. Common causes include high groundwater levels, a stuck float switch, clogged discharge lines, or a sump pump that’s too small for your home’s needs.
A sump pump is designed to move water away from your home before it can cause flooding or foundation damage. During periods of heavy rain or rapid snowmelt around the Inland Northwest, it’s normal for your sump pump to run more often. But if it runs constantly, even when the weather is dry, it’s usually a sign something isn’t right.
One of the most common problems is a stuck float switch. This is the part that tells the sump pump when to turn on and off. If the switch gets jammed or damaged, the pump may continue running nonstop. Spokane Valley homeowners also commonly deal with clogged or frozen discharge lines during colder months, which can prevent water from properly leaving the system.
Another issue could be a failed check valve. Without a working check valve, water can flow back into the sump pit after being pumped out, causing the system to cycle repeatedly. In some homes, especially older properties or homes with persistent drainage issues, the sump pump itself may simply be undersized for the amount of groundwater entering the pit.
A constantly running sump pump shouldn’t be ignored. Overworking the system can shorten the lifespan of the pump, increase energy costs, and raise the risk of failure during the next major storm. If your sump pump won’t stop running, Mainstream Electric, Heating, Cooling & Plumbing can inspect the system, identify the cause, and help protect your home from water damage before a small issue turns into a flooded basement.
