Your sump pump is essential because it carries unwanted water away from your home, particularly in your basement. It’s important to keep the pump working efficiently to avoid water damage, and you should be aware of any problems that need professional plumbing repairs. The answers to common questions below will help you troubleshoot sump pump issues. 

Common Questions on Sump Pump Problems 

What are the most common causes of failure?

One of the big reasons that sump pumps fail is a power outage. Having a backup generator or battery will help to keep your pump working if there’s a power cut during a storm, which is also a time when the risk of flooding increases.

Another common cause of failure is when the switch that turns the pump on or off gets stuck. This sometimes happens because the pump shifts, and the float that operates the switch gets lodged. Putting the pump back in the right position should fix this.

What happens if discharge lines are blocked?

Water may stop flowing through the discharge lines if they get blocked by debris or are frozen, and the water will flow back towards the sump tank, causing rising water levels.

An expert will need to investigate the discharge line to see what’s causing the blockage and provide necessary plumbing repairs. In winter, ensure the discharge lines are insulated to prevent them from freezing. 

Why is the pump constantly running?

One cause of a pump running non-stop is if the pump is too small and can’t deal with the amount of water in the tank. It will also be overloaded if the pit is too small and always full.

Another cause is if the float switch is stuck in the ‘on’ position. A pump that doesn’t stop running will burn itself out, so you should get the problem fixed as soon as possible. A plumber can tell you what size pump is right for your sump.

What maintenance is required?

Regular maintenance keeps your pump in good condition and will help you to avoid problems. Test the pump every season by pouring water in to ensure the float switch turns the pump on and off as required.

Also, check the sump pit for debris and ensure the discharge pipes are not obstructed. If you have battery backup, check the battery is charged and read the owner’s manual to see if it has reached the end of its life span.
