While a sump pump is a great device, like any piece of machinery, it wears down over time, meaning it's important to maintain them to ensure they last as long as possible.
Firstly, you should know basic information about your sump pump. This includes what type of sump pump it is, any parts that might need to be replaced, any ongoing issues, and the approximate age of the device. It's also important to clean the device every now and then, as well as ensure any vulnerable equipment is well protected. If you notice any rust, damaged parts, or strange odours, there has probably been some damage.
Another critical step in sump pump maintenance is to test the device regularly since you want to avoid finding out in the middle of a heavy storm that your pump needs to be fixed. When testing your pump, be on the lookout for strange noises, including rattling and jamming, among many others. Has trouble starting leaking fluids, excessive vibrating or the device turning on and off more or less intermittently than is normal.
If you notice anything wrong with the device at any point and aren't sure how to fix the problem, you are advised to call a professional or replace the pump entirely. How long a sump pump will last depends on several factors, and although 7-10 years is an approximate guideline, good maintenance can extend its life. A well-cared-for sump pump can protect your basement from flooding for a long time.
