Connect Delta Faucet to Home Wi-Fi

Smart faucets are not often the focus of attention when people want to build a smart home. Smart locks, thermostats, motion sensors? Sure. However, smart faucets can offer hands-free operation – as we’re used to from Alexa and Google Assistant-enabled devices – and help save water. It is precisely for these reasons that Delta’s new intelligent faucet with Touch2O technology won our Editor’s Choice Award for the CES in 2018. When Delta offered to have its TRINSIC single-lever pull-down kitchen mixer tested with Touch2O technology, we were curious to see how its technology would work in a real room.

What is Delta Touch2O Technology?

With Delta’s new Touch2O technology, you can turn the water on and off by simply touching any part of the handle or faucet. You can also slide your hands under the faucet to turn on the water – technology you’ve probably seen in public toilets. Now this hands-free technology can come to your home along with TempSense technology that measures water temperature.

While this is a great idea, installing Delta’s smart faucets with Touch2O technology is not easy. The process is similar to installing a regular kitchen or bathroom faucet – but there are several additional steps. Before you begin, make sure you have safety glasses, an adjustable wrench, Phillips screwdriver, flashlight, bucket, drill, 3/32 “hex wrench, and pencil. Also, check for an electrical outlet underneath the sink with a good WiFi signal, otherwise there will be problems controlling the Delta Smart faucet by voice or touch.

Follow the instructions to connect Delta Faucet to your home Wi-Fi network.

Delta does not have a dedicated mobile app with installation instructions or a setup guide. Instead, you need to go to either the App Store (iOS) or Google Play (Android) and download Delta’s BILT app. You can easily follow the installation with step-by-step instructions and pause the animated screens if problems arise or more time is needed.

To start with, install this Delta smart faucet just like any regular faucet. After removing the old one, mount the new faucet on the counter. Be sure to attach the mounting bracket to the sink. Next – and this is important – install the check valve assemblies on your supply stops. Make sure to insert the ferrule into the cold water stop and then unscrew and tighten the check valve. Repeat the process for the hot water stop. (Note: the water stop is the water pipe that comes out of the wall.)

These are the ferrules and check valves that you need to install in order for your Delta Faucet to work properly with Touch2O.GearBrain

The ferrule is a small gold and black piece that is located in the check valve in the box. It controls the flow of water and if not installed properly, water will not flow – and the Delta smart faucet will not work. Note: If there are multiple lines connected to your water supply stops, the Delta Smart faucet will not work properly. In our first test house we had several lines (some went into the dishwasher and the ice cube maker) that prevented the Delta smart faucet from working. We called Delta Customer Service and learned that we needed dedicated plumbing for the faucet to work properly.

Our second test house had dedicated lines, and that’s where we installed the valve.

Power is also vital to the device as you need to connect the solenoid valve and voice module in order for the Delta Smart faucet to work with your voice or in hands-free mode. Installing these was a little tricky, especially if you have a tight space under the sink. Once it clicks into place, however, the module is firmly in place and the clips that secure the hose are easy to use. You must also connect the module and the backup battery to an electrical outlet. Our test house had a waste disposal system connected to a socket, through which we supplied the module with power. You can tap into battery power, but Delta does not recommend it and you will be using many batteries.

Once you’ve installed the faucet, you can connect to Alexa. Start by searching for “Delta Faucet” in Alexa Skills, as Delta does not have its own app to operate the faucet, only one for product information. Once you have enabled Delta’s Alexa capability, you can ask Alexa to do things like “Alexa, please Delta to turn it on” or “Alexa, please Delta to dispense 1 cup of water”. Delta currently neither works with other language platforms such as Google Assistant or Apple’s Siri, nor does it integrate into other smart home systems such as Samsung SmartThings, Iris von Lowes or Nest. If you want it to be part of a smart home system, you need to use Alexa as a hub.


Delta’s smart faucets with Touch2O technology have a list price of $ 655.45 and can be purchased in plumbing stores as well as online at ACE Hardware, Amazon,, Lowe’s, and, to name a few.

Delta offers 24 different designs of kitchen faucets and 12 bathroom faucets with Touch2O technology. When reviewing the designs, there are many to choose from that will suit your kitchen or bathroom design.


Delta’s smart faucets with Touch2O technology are unique – but they are expensive. We sure like how you control the faucet with a simple touch or movement – great when your hands are dirty – and how it saves water. However, we would like the faucet to be integrated into other smart home systems such as Iris von Lowes or Samsung SmartThings, which also have intelligent devices. We would also prefer if Delta had built in a water monitoring function as well.

At just over $ 650, the price of the Delta smart faucet may seem high, but it’s actually pretty fair when compared to other high-end faucets. Our main concern is that the faucet will only work if you have a special water supply stop. If not, you may find a solution, but it should be considered before buying. If your water setup is working we recommend the Delta Smart Faucet with Touch2O technology as it saves water (and hopefully lives a little greener) and can now expect to work in your kitchen in that smart, hands-free way.
