How long does a sump pump last?
A sump pump lasts about 7 to 10 years, one of the shortest lifespans of any home system. Enter the install year and this calculator shows the remaining life and when to replace it, ideally before the next big storm rather than during one.
Test yours a couple of times a year by pouring water into the pit, and consider a battery backup so it keeps running when the power goes out in a storm. A failed sump pump is the classic cause of a flooded basement.
These lifespans are typical ranges for a well-maintained unit. Hard water, heavy use, and skipped maintenance shorten them; regular service extends them. Use the estimate to plan a replacement fund, not as a firm expiration date.
