Much of Macomb Township sits on dense glacial clay. Clay drains slowly, so after heavy rain or a fast snowmelt, water collects in the soil around your foundation instead of soaking down. Your weeping tile carries that water to the sump pit, and the pump is the only thing moving it back outside. When the pump stops, the water table around your basement keeps rising until it finds a crack, a floor joint, or the gap where the wall meets the slab.
Spring is the hardest stretch. Frozen ground thaws from the top down, so meltwater and April rain hit soil that can't absorb them yet. Winter brings a different problem. A discharge line exposed to the cold can freeze solid, and the pump keeps running against a blocked line until the motor burns out.
Michigan's plumbing code also matters here. Sump pump discharge counts as clear water, and it can't connect to the sanitary sewer. It has to go to daylight, a dry well, or an approved storm connection. Older homes sometimes still have a sump line tied into a basement floor drain or laundry tub. If we find one, we'll show you how to reroute it correctly.
