Why should you buy A Sump Pump Alarm?

Best Sump Pump AlarmWhen encountering the question “Who needs a sump pump alarm?” we would answer Everyone needs it who is in danger of floods during the rainy season, and not only then.

It is very easy to use. You can mount it to the wall or close to your sump, or even a little farther away depending on where the sump is. Next, these are some very loud audible alarms that will notify you when your portable sump pump or small sump pump has failed. This characteristic alone is a good argument to get an alarm because you simply can’t miss it when it goes off.

Slight trouble occurs if the alarm doesn’t go off. Ok, not slight trouble but a big one. So this is why we highly recommend that you get an alarm that relies on at least 2 power sources – the AC and a battery backup. If you pair it with a battery backup sump pump, then you will surely have some maximum protection against water damage. That’s what we call smart investing.

Additionally, these alarms are easy to test. You can simply simulate flooding circumstances at home and see if the device sends a signal. In one of our other sections we go through the various types of alarms and this is how you will find out exactly what needs to be done in order for the system to be tested.


Sump Pump Alarm ReviewsIn terms of installation, you do not need much. Get the instruction manual, find some mounting straps and trust the good old screwdriver. That’s all – nothing special.

  1. If you own a sump pump alarm with a battery backup, then put the batteries. Most of the units require 4 of them. You can use alkaline high-powered lithium batteries.
  2. After that, mount the device at eye level on the discharge pipe above your sump pump pit basin.
  3. Use the mounting straps to secure and fasten the unit to the pipe.
  4. Most of the alarms include two sensors. The first one is a digital sump pump float switch, which is perfect for basins with heavy inflow or splashing. The digital water sensor is the other one, it is great for early detection and water pan or overflow applications.
  5. Snap the end of the sensor into the input on the bottom of the unit. You may plug the sensors into either input one or input two.
  6. Repeat this process for the second sensor. Fix the sensor to the discharge pipe inside your basin. The height may change based upon your specific needs.
  7. We recommend that you mount it at a height that rarely gets water but not so high that you don’t have ample time to prevent a flood when you get your notification.
  8. Plug the unit into the outlet and flip the power switch on the control panel. The light may indicate that it is trying to find a signal. Then it will turn to solid green when it is connected to the near cell tower.
  9. Press and hold the configuration button. You will hear the beep and the red and green blinking light pattern indicate that the unit is in configuration mode.
  10. Your unit cannot receive your text messages until it is placed into configuration mode the unit automatically exits configuration mode after about one hour.
  11. You previously created a sump pump alarm contact in your phone. Right? Use the standard command phone one then a space followed by your mobile device number. Your unit will receive the message acknowledged with a beep and send a status reply.
  12. To program the second and third numbers in your unit repeat the step. Use the command phone two and three respectively. Follow the command with the number you want to receive a text. These are optional numbers and don’t need to be programmed if you need only one number.
  13. If you simulate a high water level you will receive a text message warning from the alarm.
  14. You can also simulate a power outage by pulling the plug from the side of the unit.

Types Of Sump Pump Alarms

Benefits of Sump Pump AlarmEveryone has different preferences. That’s why the market gives you a variety of different choices, such as different sump pump alarms or water leak detectors. We know that it is very difficult to make the perfect choice for your home.  That’s the reason why we explain the different types of sump pump alarms in a simple matter. The types are:

Standard– These units don’t have a lot of features. The alarm warns you only with the sound of beeping or buzzing. The positive side is that these units are very cheap, and they are the right choice if you don’t want to spend a lot of money.

Phone or Auto-Dialer – these ones are sump pump alarms that call your phone. They are a bit more advanced. They work similarly to the standard ones, but as you may understand from their name, except for the warning sound they can call your phone to warn you for danger if you aren’t at home.

Sump pump alarm with wifi  A.K.A an Auto Dialer –  this one works absolutely the same as the Phone Dialer sump pump alarm, with the difference that it doesn’t use the local cell tower, but use your WiFi connection not only to call you for an emergency but also to send you reports. You can always check online if the alarm’s working properly.

Cellular sump pump alarm – again, this unit works such as the first one we have talked about above. They contact you by phone but don’t use WiFi or phone line. Such gadgets require a cell service plan. Some of them come with a cellular card or separate cell phone which is used only for the alarm.
