Tips to Avoid a Sump Pump Disaster
Listening intently for the reassuring hum of their sump pump is common for homeowners. That sound signals that your basement is being protected from water damage, especially when snow begins to melt or during heavy rain. But what happens when it keeps running? If your pump seems to be working overtime, there are several possible reasons why. Understanding these causes can help prevent unnecessary wear on your pump and avoid potential water damage.
What is a Sump Pump?
A sump pump prevents basement flooding by activating when water levels rise. Installed at the lowest point of the foundation, the sump pit collects water. When it reaches a certain height, the pump expels the water through a discharge pipe outside. It operates until the water level drops, protecting your home from damage.
Why Does My Sump Pump Keep Running?
It’s only seemingly dry
Just because the sun is shining doesn’t mean that the ground beneath your home is completely dry. Groundwater doesn’t disappear instantly. It moves slowly through the soil, sometimes pooling near foundations before fully draining away. If your home is in a low-lying area or near a body of water, the natural movement of groundwater can cause your sump pump to run even in seemingly dry weather. Additionally, a small or less powerful sump pump might take longer to clear accumulated water, leading to prolonged run cycles.
Stuck or broken float switch
Your sump pump operates based on a float switch, which detects water levels and signals the pump to turn on when necessary. If this switch gets stuck in the “on” position, your pump may run continuously, even if water levels are low. This can happen when the float becomes jammed against the side of the sump pit or tangled with debris. If you notice your pump running non-stop, try gently freeing the float to see if that resolves the issue. If the float is damaged or worn out, it may need to be replaced to restore proper function.
Clogged drain or discharge line
Sump pumps work by collecting water and directing it away from your home, but if the discharge pipe or drain becomes clogged, the system can struggle to expel water efficiently. Dirt, sediment, and small debris can accumulate over time, restricting water flow. In colder climates, leftover winter ice can also create blockages in outdoor pipes. If your pump is running but seems to be discharging water slowly or not at all, check for visible clogs. A minor obstruction may be cleared manually, but if the blockage is deeper in the system, you may need professional assistance to restore proper drainage.
Other Issues
In some cases, a constantly running sump pump could indicate a more serious problem, such as a malfunctioning check valve. This valve prevents water from flowing back into the sump pit after being pumped out. If it’s faulty, water may continuously cycle through the system, forcing your pump to run unnecessarily. Additionally, a power issue, such as a faulty electrical connection or an aging pump nearing the end of its lifespan, could contribute to irregular operation.
While your sump pump is a crucial line of defense against basement flooding, it shouldn’t run non-stop. If you notice your pump running excessively, take the time to inspect for these common issues. Addressing minor problems early can prevent more significant, and expensive, repairs down the line. If you’re unsure, schedule an inspection with Action Plumbing to help ensure your system is in tip top condition.
