Buyers Guide for Whole House Automatic Water Shutoff Valve

Water detectors have become an essential part of every household. They are easy to use and manage. But, we have loads of suggestions on which water detection system to choose and which one to avoid.

So, what’s best for you?

Well, it depends on various factors such as the place of installation, members in your family, and if you are an avid traveler or not. But, some of the most important aspects of a water detection system are its quality and efficiency.

Besides, these factors should never be overlooked when looking for a new water detection system.

Good quality sensors

The prime purpose of installing a water leakage detector is to prevent flooding timely. If the sensors are not efficient and don’t work 24/7, they will most likely fail in instant reporting.

Therefore, one should always look for water leak detection sensors that are prime quality ones. Some of the water leakage detectors mentioned above have one to two sensors and instant alarms or send immediate alerts on your mobile. Ideal water leakage detectors are those that can detect the slightest pinpoint leakage promptly.


Every modern gadget is technology-friendly. We cannot simply rely on alarms to prevent flooding. Most water leak detection systems are compatible with WiFi and send alerts through smartphone apps.

Therefore, always consider a water leak detector that is technology-friendly and has the ability to send instant alerts on your personal phone.

Automatic shut-off system

What’s the point of installing leak detection when it can’t prevent flooding? There are water leak detectors that do not offer an automatic shut-off system, rather offer instant alerts.

But, the better ones are with automatic shut-off systems. They are very efficient and work almost instantly. Most of the above-mentioned auto shut-offs work in less than seconds. These automatic shut-off systems are connected with the water mainline. They also send you regular alerts daily.


The price of a water leak detection and automatic shut-off system ranges from $500-$15. It depends on what you are looking for.

If you can buy a fancy water leak detection device, get yourself Moen 900-006 Flo by Moen 1-Inch Smart Water Shutoff. They are great! Their instant alerts and daily reports of water consumption are beneficial. And, they are really making an effort to save mother nature by suggesting ways to save water from wastage in your daily life.

However, if you want a cool affordable piece of water leakage detector, Smart Hot Water Heater Shutoff System will be perfect for you.


The size of the sensor device matters more than anything. We would never want an oversized water leak sensor device with a small hose. These factors limit mobility and prevent them from working at their best.

You will have to contemplate where exactly you want to put it. If you are placing it inside a narrow pipe, a sensor that can be fixed with ¾ inches diameter will be ideal for you.

There is a wide variety of diameters, from ¾ inches to 1 inch and 1 ¼ inch. Find what’s best for you!

Final Verdict

It is indeed correct that the chances of flooding are greater than a fire breakout. Therefore, we should prepare for every condition. A smart water leak detection and automatic shut-off system with built-in sirens and smartphone compatibility is all that you need. All of the above-mentioned factors determine what’s suitable for your use. From portable to huge commercial purpose sensors, we have mentioned a variety of leak detectors.

You will have to assess what is best for you, whether you want a portable sensor device or a sensor with vacation mode. One of the most used features in leak detectors is auto shut-off. They are pretty much a lifesaver, especially when you have pets and kids in your house.

Be careful with what you buy. Most Whole House Automatic Water Shut-off Valve comes with a warranty, but not all offer one. You are indeed taking a step towards making your house more safe and secure. Get the best water leak detector right now and live your life peacefully.
