Sump pumps are a critical piece of equipment in many homes, preventing flood damage that can destroy possessions and property. A sump pump alarm lets you know when the water level is rising in the sump pit. It’s helpful to know when this is occurring as water damage is one of the most catastrophic events you can experience as a homeowner. These units are also referred to as a “high water alarm for sump pump.”
Sump pump alarms alert you to conditions that you should be aware of. If your primary pump has failed, water is rising too fast for the pump, or the backup battery is dead, these are some of the reasons you could hear the alarm go off.
Some sump pumps include alarms as part of the kit, but it can be helpful to have an additional alarm in place, and if you choose one with email, voice, and text alert capability then you can stay informed even when you’re away.
Here are some of the best alarms for you to choose from, ranging from relatively simple models to more tech-oriented solutions that can alert you in multiple ways.

This isn’t specifically intended to be only a sump pump alarm, but it is a good all-purpose water level monitor so that you can be alerted to water-related conditions anywhere you set it up. It’s a very affordable device that can save you a lot of money and hassle.
You may want to use one of these in conjunction with other systems. Some people use these anywhere they have plumbing fixtures that could leak, so don’t think of this as an option that’s limited to use in your basement, although it’s a good choice as a high water alarm for sump pump systems.

Here is a unit that’s perfect for you if you want to have notification methods other than just the sound of an alarm. What if something happens when you’re away from home? If the water level starts rising, this system can notify you via email, voice, or text alerts. Note that the email alerts come free with the purchase of this unit but the voice and text alert service is an add-on that costs a little over $10 per year as of this writing.
This system is available with either the precision probe or float switch to detect water levels. The precision probe is able to detect water levels within 1/4 inch. The precision probes can only be use in clear water applications such as sump pumps (without any floating debris), pool pumps, and rain water. There isn’t a great price difference between the precision probe or float switch models so it comes down more to what your preference is rather than what your budget looks like.
Final Thoughts
A high water sump pump alarm is a recommended addition to your sump system, because when the water level starts rising, you need to be aware of the situation. It’s a small investment to make to help protect your property and give you peace of mind.
