Catching water damage early can make a huge difference, and in this Simplisafe water detector review we will show you a handy device that can help reduce the probability of severe water damage.

Overview Of The SimpliSafe Water Detector

The SimpliSafe water detector is a simple yet effective tool against water and flood damage. You can place the small and compact detector in areas where you think flooding and water issues could be a problem, and then it will alarm you when it detects water.

We have seen before how SimpliSafe has a great track record with its security products, and this water sensor is no exception.

Throughout this review, we will go into more detail about what this detector has to offer in terms of features and benefits.

Importance Of Having A Water Sensor For Safety And Home Protection

In the past, we have looked at why it’s important to have comprehensive security measures for your home. As we touched on before, water damage can be devastating when it occurs. It can ruin floors, electronics, and sentimental objects like family photos that are being stored. These are a few examples, but anything can fall victim to water damage.

Water damage can be a silent occurrence, so the sooner you can be aware of the problem the sooner you can act. Knowing about a leak early not only allows you time to remove valuables from the area but may also let you fix the problem before it gets worse.

Having a water sensor can allow you to get an early heads-up before it gets worse. Floods and other natural disasters have become more and more frequent in recent years, so it’s vital to be one step ahead, as we have covered before.

Key Features And Benefits

SimpliSafe Monitoring Plan Integration 

SimpliSafe offers an optional monitoring plan subscription for many of its safety products. While these plans aren’t mandatory for using the sensor, you definitely get the most out of the product by being a part of this plan.

Linking the sensor to the monitoring plan means you will get email alerts straight to your smartphone, meaning you can be aware of flood or water damage even if you’re on vacation. We have previously looked at why these kinds of monitoring plans are always a good idea.

Sends Time Sensitive Alerts To Mobile App

If you link your sensor to the SimpliSafe app, you can also get alerts that way, meaning that you will be unlikely to be caught unaware if flooding occurs.

As with most SimpliSafe products, it’s well worth it to take advantage of the extra features they offer.

Protect Your Home From Flood Damage

Flood damage is something that no one needs in their lives. We have touched on how devastating it can be, and it’s even worse if you don’t find out about it until it’s too late.

The sensor will give you the best chance possible to know about the problem before it becomes a major issue.

Wireless Operation

It’s pointless having a device like this one if you will need to constantly worry about how to power it or whether it might die on you in a time of need. Luckily, the SimpliSafe leak detector has a simple, wireless design that means you won’t have to be constantly checking it to see if it is powered.

It also means that you won’t need tools or expertise to install it.

5-10 Year Battery Life

Having to wonder whether the batteries will last in your device is always a huge concern, but luckily it’s not something to worry about here. You will typically get between 5-10 years of battery life with the SimpliSafe water detector depending on how much it is used.

It will also alert you when the battery needs to be replaced, so it’s unlikely that you will be caught off guard.

Water Resistant Housing (No Battery Tab)

Seeing as this device is designed to detect water, it would be rather unfortunate if it would get destroyed when in contact with water. Luckily, the device has a water resident, an air-tight design which means it won’t be ruined in the case of water contact.

That means that you will be able to use it again in the unfortunate instance of future water leaks and damage.

1 CR-2032 Lithium 3V Battery (Included)

The SimpliSafe water sensor operates with a CR-2032 Lithium 3V battery, and you can rest assured that the device comes included with the battery, meaning you won’t need to source one yourself.

Design And Build

The SimpliSafe water detector has a simple, compact design that also shouldn’t draw too much attention from decor if it is in view. It’s pretty small at 4.01 inches high and 4.01 inches wide, and it weighs 0.23 pounds.

This means you can fit it into some tight spaces and it can be transported and placed around easily.

Ease Of Use

Setting up the SimpliSafe water detector is simple and easy. All you will need to do is set it up with the app if you’re planning on that aspect, turn it on, and place it in your desired location.

There should be no installation required, and ease of use seems like it was a big priority to the designers of the product.

Performance And Functionality

This water detector is very reliable and does its job brilliantly, but a bit of strategy may be needed when placing it. It is ideally suited for areas where flood and water damage is at its most likely.

Ideally, you would want to have a few water sensors placed around your house. This could be in areas such as an attic, basement, kitchen, bathroom, or perhaps near a large aquarium.

Areas where there is some kind of water connection, especially ones you won’t be seeing every day, would be ideal for a water sensor.

Pros And Cons

The SimpliSafe leak detector is a simple yet effective device that does everything you would expect. We have covered some of the benefits of the device, and these would include parity with SimpliSafe’s security systems, its long battery life as well as its compact design.

There are a few drawbacks to note, however. The device is not as useful without connecting it to the SimpliSafe app and monitoring plans. That means that you may have to pay a subscription to get all benefits.

Most reviews on Amazon and Best Buy’s websites are overwhelmingly positive, but a small number of users did have a few quality control issues. These instances do seem to be a small exception to the rule, however.

Integrating devices like the SimpliSafe Water Sensor into your home security system represents a smart approach to comprehensive home protection. It’s not just about deterring intruders anymore; it’s about safeguarding your home from all potential threats, including environmental ones. This sensor’s wireless operation and long battery life make it a seamless addition to any home.
