When Should I Replace My Sump Pump?

old rusty sump pump

Your sump pump is a critical component of your home’s waterproofing system, working tirelessly to keep your basement dry and prevent water damage. However, like all mechanical devices, sump pumps have a lifespan and may eventually require replacement. In this blog post, we’ll explore the key signs that indicate it’s time to consider sump pump replacement to ensure your basement stays protected.

1. Frequent Cycling

Frequent cycling of a sump pump can indicate potential issues, and while it’s not always bad, it’s a sign that should be addressed. If your sump pump is cycling on and off frequently, it means it’s handling a significant volume of water. While this can be normal during heavy rainfall or when the water table is high, constant cycling can overwork the pump. Over time, this may lead to premature wear and reduce the pump’s lifespan.

2. Continuous Running

If your sump pump runs continuously without stopping, it’s a clear indication of a problem that should be addressed. It could be that the sump pump is struggling to keep up with the amount of water entering the sump pit. It’s also possible that the sump pump is undersized for the volume of water it needs to handle. It could also be a problem with the float switch being stuck in the on position. Or there could be problems with the drainage system, such as a blocked or discharge pipe. This can lead to water not being expelled from the sump pit properly, causing the pump to work continuously.

This is a big sign with many possibilities. It’s best to have an expert inspect your water drainage system to truly understand the root cause of continuous running.

3. Unusual Noises

Sump pumps should operate quietly and smoothly under normal conditions. If your sump pump is making unusual or concerning noises, it’s typically a sign of a problem. Grinding or screeching noises may suggest that there’s a mechanical issue with the sump pump’s motor. Banging or clanging sounds can indicate that there are loose or misaligned parts within the sump pump which can cause the pump to vibrate and make loud noises. Or if you hear gurgling or sucking sounds, it could indicate that the sump pump is struggling to remove water from the pit, possibly due to a blockage in the discharge pipe or an issue with the check valve.

4. Failure to Activate

An obvious sign that your sump pump should be replaced is that it doesn’t turn on at all. It could have been the age of the pump, or any one of the other issues listed here. As well, if you experience a power outage and your sump pump doesn’t activate, it may be wise to invest in a Battery Backup System, so that you can have peace of mind knowing your sump pump will remove water even when the electricity goes out.

5. Age of the Sump Pump

Most sump pumps have a lifespan of about seven to ten years. As they age, their efficiency and reliability can decline. Even if your pump is still functioning, it’s wise to consider replacement to avoid unexpected failures. It could be shorter depending on the usage of the pump and the manufacturing brand.
