Different Types of Sump Pump Alarms

You must include water alarms in your sump pump system. Whether you have a built-in alarm in your sump pit or a traditional beeping water alarm unit, you’ll be warned of imminent flooding dangers before they happen so you can respond before the issues begin. These are the three most common sump pump alarms.

Traditional Water Alarms

A sump pit alarm is a traditional water alarm. It beeps loudly from the sump pit in the basement when water is present. These alarms are loud enough (sometimes over 100 decibels) to hear on the house’s second floor. 

These alarms are helpful when you are home, but when you are away, they are useless. These are the least expensive water alarms.

WiFi Alarms

Alarms wired to your sump pit can send you text or email notifications even if your sump pump doesn’t. They are a bit more costly than purchasing a traditional sump pump alarm, but they will alert you if anything goes wrong in your sump pit. 

Specific newer water alarms have mobile apps that you may log into and monitor alarm performance over time. 

These smart alarms make it simple to monitor your basement and notify you if anything goes wrong, no matter where you are. You can connect them quickly to a sump pump, sewage pump, or any other system.

Alarm Dialers

Besides a sump pump alarm system, individuals who own cabins or rental properties commonly install low-temperature alarm dialers inside the house to let them know if indoor temperatures drop below 42 degrees Fahrenheit. 

Temperature alarm dialers do not connect to the sump pump or pit but alert you when pipes might freeze and burst, flooding the house when nobody is there. 

These alarms cannot be connected to a wireless internet connection but to a landline phone line to dial. It can notify you if issues arise, even when you are away from home. You must place the alarm in the area it is being monitored.

Best Sump Pump Alarms: Buying Guide

The best sump pump alarms are not cheap, but they are pretty affordable. Usually, sump pump alarms last for the lifetime of the system. The function of the sump pump alarm is relatively minimal. 

However, before you purchase a sump pump alarm to protect your cellar, review my buying guide. It will help you choose the best sump pump alarms for your house.

WiFi Connectivity

Modern alarms can use a wireless network to send you notifications over the internet if a flood occurs. Make sure that you check whether WIFI capability is included with your model. 

This feature is ideal for people who are away from home frequently or for landlords who need to receive notifications instantly when a property is flooding. When an alarm detects a hazard or flooding, it can connect to the internet and notify your phone.

Noise Level

The decibel level is crucial when selecting the best sump pump alarms. It will help if you consider the sound level of this sump pump alarm as the most significant factor when choosing it.  

The alarm should notify you in case of an emergency. If you don’t hear it adequately, installing an alarm is pointless. 

Before purchasing an alarm, you must look at the decibel range. It must be loud enough to hear. Sump pumps require alarms with a decibel range of 85 or higher.

Power Options

Sump pump alarms usually function on electricity, but there are also battery-operated alarms. Your house should have consistent electricity if you want to rely on direct electricity. If there’s no electricity, the sump pump won’t work. You can also choose battery-powered alarms, however. 

Even if you purchase an electricity-operated sump pump, you might want to buy a battery backup model to ensure you have backup power in case of an electricity outage.

Ease of Installation

It is typically tricky for beginners to set up sump pump alarms. However, even most users do not generally have a lot of difficulties installing them. 

Furthermore, you may not always be able to install the most sophisticated alarms without a problem. Therefore, you should select an easy sump pump alarm that you can use without difficulty. 

The installation process is primarily described in the instruction manual in detail. You must also receive the optimum performance of the alarm you have purchased. 

Alternatively, you may employ a professional to accomplish this task. However, it will cost you a large amount of money.

Should You Buy A Sump Pump Alarm System?

You can avoid investing in an alarm system for your sump pump. Still, it can make a significant difference between preventing a basement flood in advance and incurring hefty water damage expenses later.

You should install an audible alarm in your basement as a precautionary measure. For those who frequently travel or own rental properties, use a Wi-Fi-connected alarm to send immediate alerts to your mobile devices.

Conclusion: Best Sump Pump Alarms

An alarm system is an essential investment for a water pump, as it may prevent a flood in the basement before it happens and saves you thousands of dollars in water damage. 

A wired alarm is essential, but if you are away frequently or own a rental property, an alarm that connects to WIFI and alerts you on your phone is a good choice. Hopefully, my guide helps you to choose the best sump pump alarms for your home.

Can you put an alarm on a sump pump?

The purpose of sump pump alarms is to notify you when the water level in the sump pit is increasing and reaching a dangerous level. Installing a sump pump water alarm ensures your pump is functioning correctly and alerted promptly.
