Why do I need a sump pump alarm?

A sump pump alarm, unlike a water leakage alarm, can detect if something is wrong with your sump pump before it reaches the floor and does any damage. These alarms use float switches as sensors to withstand and properly monitor sump conditions without triggering any false alarm from splashes and moisture. 

It’s very useful if there’s a power failure, a tripped GFCI, failed sump pumps, or excessive amounts of water coming in. It will monitor how your sump pump system is holding up 24 hours a day giving you the freedom to do more important things.

Frequently Asked Questions

Why does my sump pump alarm keep going off?

A sump pump alarm may trigger due to a number of possible reasons:

  1. Stuck float switch – check the float switch in the sump pit for any signs of it getting stuck. A vertical type may get stuck due to accumulation that you can easily wipe off while a tethered type may get tangled in the pump or the pit.
  2. Level switch position – if the switch is placed too low, it may trigger the water alarm prematurely. You can move it a bit higher if you still have room in your pit. If not, you can move the sump pump switch a little lower to keep the water from reaching your alarm when everything is normal.
  3. Faulty product – the product may be faulty due to a manufacturing defect or damage from use. Check your warranty and call customer service of the manufacturer.

How do you install a sump pump alarm?

Installing a sump pump alarm system is easy. The first thing to do is to connect the sensor to the device. Then mount the switch a few inches above your pump’s switch. The mounting kit usually comes with the product, some you can attach to the pipe but there are also those you can attach to the basin.

You can then install the controller for the alarm system itself a few feet above the basement’s floor, where there’s an outlet, the closer to the door or WiFi (if it’s WiFi capable) the better. Then, if it’s cellular or WiFi capable, configure it with the method provided by the manufacturer.

The procedure may vary depending on the product so you have to check the user manual itself for yours.
