How Do I Check My Sump Pump Before the Spring Thaw?
Before the snow melts, pour a bucket of water into the pit and watch the pump start and empty it. Check that the discharge pipe outside is clear of ice, the float moves freely and the pump is plugged into a working outlet.
Request a plumberWhy test in March?
Snowmelt and spring rain raise groundwater fast. A pump that sat idle all winter may have a stuck float or a frozen outlet.
How do I test it?
Slowly pour a bucket of water into the pit. The float rises, the pump kicks on and the water drains away. Listen for grinding or a hum without pumping.
What about the discharge line?
Follow the pipe outside. It should be clear of ice and snow and empty well away from the foundation, not right next to it.
Does it have a check valve?
Most systems have a check valve on the pipe above the pump that stops water flowing back into the pit. If the pump cycles on and off quickly, the valve may be failing.
When should I replace it?
If it's more than about 10 years old, rusted, noisy or struggling, replace it before the busy season. Many owners add a battery backup at the same time.
What if it fails in a storm?
Unplug it if it's buzzing and send an urgent request. See sump pumps.
Should I clean the pit?
Yes, once a year. Remove gravel, silt and debris that can jam the float or clog the intake. Unplug the pump first, and wear gloves.
Is there an alarm I can add?
A simple battery water alarm in the pit or on the floor warns you before water reaches belongings. Some connect to your phone, which is useful if you travel in spring.
