How Does a Sump Pump Alarm Work?

A sump alarm can alert you whenever you have way too much water in your sump basin. This can prevent any water damage after a storm or heavy rain since you can just clear the basin by triggering the sump pump whenever you want.

There are many types of sump pump alarms, but most of the best ones use a sensor or a float, and they basically check the water whenever it exceeds a certain amount and alert you through a typical alarm system or WiFi.

Some other alarm systems rest at the top of the sump pump itself, and it alerts you whenever it comes in contact with water.

Why Do I Need a Sump Pump Alarm System?

A sump pump alarm system is a must for any house with a sump pump. Your sump pump can often get issues, and even if it doesn’t, your sump basin can flood if too much groundwater accumulates.

This usually only happens when there is a storm or heavy rain, and it can lead to water damage. But with a simple sump pump alarm system, you can easily be notified whenever there is an unusual amount of water in the sump basin, and you can take action when necessary.

The damage from the excess water exceeds the price of the sump pump alarm itself, so it’s overall a great investment and can save you a lot of trouble.

Buying Guide for Sump Pump Alarms

When buying a sump pump alarm, you should look for these things —

Loud And Clear Alarms

When picking a sump pump alarm, always ensure that the alarm is audible enough to be heard from any point in your house. Any number above 80 decibels can work well.

Reliable Monitoring Systems

Make sure that your sump pump alarm isn’t buggy and that you can reliably check the water levels in your sink basin.

Compatibility With Most Sump Pumps

Another of the most important things about sump pump alarms is for them to be compatible with sump pumps. You won’t have to worry about this too much though since most of the alarms on our list work with most pumps.

No Battery Required

If possible, try getting a sump pump alarm that doesn’t use a battery, as it requires much more effort to maintain these than a regular alarm that connects to a wall outlet.

Quick Alarm

Make sure that your alarm notifies you as quickly as possible since even being a little late can cause your sink basin to be completely filled up and flood with excess water.


Now that you have a good idea all about sump pump alarms, here are some of the most frequently asked questions to clear any further confusion —

What to do when the sump pump alarm goes off?

Most sump pump alarms are high-water alarms, so they’ll go off before the water is too high. So even if the alarm goes off, you won’t have to panic, and you can slowly take your time to examine the water in the sump pump system. Then if needed, you could dry the excess water out and let the sump pump do the rest. After all, as long as the water isn’t too high, the sump pump can deal with it perfectly fine.

How to turn off the sump pump alarm?

The way to turn off your sump alarm varies from alarm to alarm. But most of the time, you can find a rectangular white box from the area where the noise is originating from. From there, you can toggle the switch to an “off” position, and your sump pump alarm will be turned off. In addition, some alarms come with a WiFi system, so you can automatically turn them off from your phone.

Can you put an alarm on a sump pump?

Yes, you can put an alarm on a sump pump. In fact, when you get a sump pump, there will already be some sort of alarm system to prevent flooding or water damage. If not, you can always get a separate alarm system and hook it up with your sump pump at any time, and it’ll work as usual.
