How to choose The Good Sump Pump Alarm:

“Prevention is better than cure”, agree with this saying? Yes, before your sump pump gets fully damaged due to water problems, don’t you think it is your duty to save your sump pump before it gets damaged? If you think so, then sump pump alarm is the only solution. But how to choose such one? With no waiting, let’s skip to 8 important factors that you need to consider before choosing an alarm.

  • Reliability:

Sump pump alarm simply notifies you when there is a water leakage, power cut, overflowing, change in temperature or any other defects. But not all alarms do the same job. Therefore know what your main requirement is. Because each alarm is best for its own features and lacks another. Therefore by knowing your requirement, you can choose the right one.

  • Wi-Fi connectivity:

In order to receive notification, or to connect with a siren, or to connect with an app you need to have a Wi-Fi connectivity. Therefore Wi-Fi is a required feature in a sump pump alarm. It also helps to customise the features of alarm through the application as per your need.

  • Loud alarm:

This is the most important feature among all. Only when the sound is loud, you can hear the alarm and take necessary steps. Therefore choose a loud one. You can also connect it to a siren using Wi-Fi connectivity for a louder sound.

  • Mobile/ email notification:

When you are out of your house, Wi-Fi connectivity is not reachable. Therefore choose an alarm which can ping you using voice call or text messages or through email. This can help you from serious risk even when you are out of your home.

  • Durability:

This is a common feature that any customer will look for. Therefore go for a popular and long lasting alarm. Don’t be rational while spending money. Because if you go for an unreliable product (considering low price) it might lead to a bigger risk when the alarm fails to fulfill its work.

  • Customizable alarm:

Based on your need go for a customisable alarm. There are applications (D-LINK DCH-S160 uses Mydlink home app) which are connected to the alarm through the Wi-Fi network and can be customisable as per your need.

  • Warranty:

Do consider the warranty period provided. Because you can replace the product at no cost during such period.

  • Usage:

Know whether you need it for indoor or outdoor use. Few alarms are specially made for indoor usage rather than outdoor usage and vice versa.


There are plenty of alarms available in the market. Each and every one has their own merits and demerits. Based on your need match with the right one. One can be the best alarm if it satisfies your need. Hopefully, our list can give you all necessary information about the product and guide you to match your requirements with the right one. Consider all the above mentioned features before buying an alarm. Choose the best and have a peaceful life.
