Top Pick: Zoeller A-Pak Indoor Alarm System

Zoeller is famous for their sump pumps but they also make alarms you can count on like our favorite – the Zoeller A-Pak Indoor Alarm System!

The alarm is loud enough for both indoor and outdoor usage so you know when your pump is failing and water is rising!
We recommend installing this alarm with any Zoeller pump so you know right away when a pump is not working. Zoeller products rarely fail but they do experience motor problems as well as other problems like power outages that can keep them from working.

Sump Pump Alarm Buying Guide
Having trouble deciding which alarm is right for your basement? Here are a few factors that we always review before recommending an alarm.
1. WIFI Connectivity
Newer alarms can connect to your wireless network and send you alerts over the internet when a flood is detected. Not all models have WIFI functionality so make sure to double check that you will be able to connect!
This feature is great for homeowners that are often away from home or for landlords that need to get alerts right away when a property is flooding. By connecting to the internet the alarm is able to call your phone when it detects a problem or flooding.
2. Noise Level
Got a deep basement or an exterior cellar? Then you will need a super loud alarm if you want to catch a flood in time! Some audible alarms are much louder than others – with the loudest around 90 dB and others being a little louder than a phone call. Make sure you choose an alarm that is loud enough to hear anywhere in your home.
3. On-board Battery
Most alarms are powered by a cord running to a wall socket but some also have battery backups. If you live in an area with heavy storms, lots of trees that fall on power lines or are installing the alarm in a vacation home we recommend picking a battery powered system with an alarm.
4. Multi Use Functionality
Some alarms we reviewed serve multiple purposes. Zoeller, Superior Pump and others make sump pumps with built in alarms and other functionality like mold detection.
