Leading the Way in Sump and Septic Protection – Our Story

Sump Alarm began after the founder’s basement flooded on Mother’s Day weekend in 2009. We saw the need for remote sump pump monitoring to prevent costly damage. This inspired the creation of the first wireless-enabled outdoor sump alarm.

Our products are built to withstand harsh environments. They are made in the USA and include US-based support. Unlike others we focus solely on alarms.

Sump Alarm prevents costly water damage with real-time alerts and remote monitoring. With proven protection for your home.

Water and septic damage can lead to significant financial loss and emotional stress. With Sump Alarm’s reliable monitoring solutions, you can prevent disasters before they happen—giving you peace of mind and protecting what matters most.

Best Sump Pump Monitor

Previously purchased Moen monitor and had to return it two times. The Moen system has serious flaws, especially with the sump monitor. It would set off false alarms every 20 mins and no matter how it was adjusted it never worked. The level sense uses a float monitor which makes more sense and really works. Moen Wi-Fi was very glitchy, Level Sense worked on the first try. Level Sense customer support is based in St Louis and are very helpful. It was worth every penny!

If you have a sump or sewage pump, you absolutely need one of these

I installed my level sense pro in 2017. We are in 2025 now and there have been many points where I wondered if the thing was still working or not, and then out of nowhere, will get an alarm alert by text message that something with my pump system is amiss. From laundry washer failures to cold weather pumping issues, this thing has saved me money and heartache time and time again. The notifications and alerts are so helpful and have prevented disaster for me on more than one occasion. Including this morning. I installed my level sense pro in 2017.
