Here are six things a professional should examine during an annual inspection of a sump pump, according to the InterNACHI.

1. The pit. A sump pump sits in a pit that gathers and collects water until the pump removes it. A professional should ensure that the pit is large enough — at least 24 inches deep and 18 inches wide, says the InterNACHI — for the sump pump to function properly.

2. The check valve. A professional should make sure that there is a functioning check valve installed on the discharge pipe. The check valve helps prevent water in the discharge pipe from flowing back down into the pit after the pump turns off.

3. A backup power source. Sump pumps may need to need to work harder during extreme weather conditions where heavy rains may result in power outages. A professional can confirm whether there is a backup power source on a sump pump, such as a battery, and that it is in proper working condition.

4. The alarm. While not all sump pumps are required to have alarms that sound when the device is activated, they can help alert a homeowner that there is water buildup in the pit. If a sump pump has one, it should be tested to help ensure it functions properly.

5. The cover. Since sump pump pits collect water, they should have a removable cover to help prevent water from evaporating into the basement. A professional will ensure it fits properly or should help add one, if needed.

6. The discharge location. A professional can alert homeowners if their sump pump's discharge location is improper. It is recommended that the discharge location be at least 20 feet away from a home to help prevent water from draining back towards the house — and it should not drain onto neighboring properties, into public sewer systems or into a residential septic system.

Remember that a sump pump helps prevent excess ground or rainwater from entering your home. With regular maintenance, you can help keep your sump pump working properly and your basement or crawl space dry.
