Installation of the nozzle on the Xiaomi crane: a complete guide with photos and tips

Xiaomi's smart home accessories have long since ceased to be exotic, now it's the standard of comfort. Among the company's most sought-after gadgets are tap nozzles that save water, filter it or add functionality like backlights. But many users face difficulties in installing: threads don't fit, gasket leaks, instructions in Chinese. In this article, we'll examine the step-by-step process of installing Xiaomi Mijia, Viomi and other models, and reveal secrets that are not written in official manuals.

We analyzed owner reviews, independent expert tests and technical documents to gather the most complete guide, and here you will find not only basic instructions, but also solutions to problems ranging from thread mismatches to connection errors to the Mi Home app. And if you already have experience installing, take part in our survey below!

And just to put it right: despite the visual simplicity, mounting a nozzle requires attention to detail, 90% Leaks are caused by improperly installed gasket or thread skewing.In addition, not all Xiaomi models are universal - some are only for externally threaded cranes. G1/2 or G3/4. If you do not take into account this nuance, you risk buying an accessory that simply will not be screwed into your mixer.

1. Compatibility of Xiaomi nozzles with your faucet: how not to make a mistake when buying

The first and most important step is to check if the model you choose fits your mixer. Xiaomi has three types of nozzles:

• 🔧 Universal – suitable for most cranes with threads G1/2 or G3/4 (Mijia Smart Faucet Lite).
• 💧 For filtration – require connection to the water supply (Vomi models with reverse osmosis system).
• 🔄 Replaceable – attached to an existing nozzle (for example, Xiaomi Youpin Aqara Water Purifier).

To avoid error, measure the diameter of your crane thread with a rod or use a simple life hack: attach a coin to the rod. 5 RUB – if the carving is a little narrower, this G1/2 (21 mm), if the same — G3/4 (26 Xiaomi nozzles with internal threads are extremely rare - most models are designed for external threads.

Also note:

• 📏 Crane length: if the mixer is too short, the nozzle may rest against the sink.
• 🔩 Material: Brass cranes are compatible with most nozzles, and silimine cranes may require adapters.
• 💡 Functional: Some models (e.g. Viomi) V-RFM01) Requires connection to the power grid for lighting.

⚠️ Note: Xiaomi’s temperature sensor attachments (such as the Mijia Thermometer Faucet) do not work with cranes with a side lever – the sensor will not be able to read the data correctly.

Preparation for installation: tools and safety

Before you edit, make sure you have everything you need.

• 🔧 Dilution key (better with rubber sponges, so as not to damage the cover of the crane).
• 🧻 Clean cloth or wipes – to remove moisture and dirt from the thread.
• 🧴 Silicone lubricant or FUM tape (if there is no gasket in the kit).
• 📱 Smartphone with Mi Home app (for smart models).

Important: If your tap has been in use for a long time, the thread may be contaminated with lime deposits, in which case clean it with vinegar or a special tool (for example, Cillit Bang), otherwise the nozzle will not be screwed into the end.

Also check:

• 🚰 Water pressure: if it exceeds 6 bar, you will need a gearbox (many Xiaomi nozzles are designed for 1-5 bar).
• 🔌 Availability of a socket (for models with backlight or display).
• 📶 Wi-Fi signal at the installation site (for smart nozzles).

⚠️ Warning: Do not use metal brushes to clean the threads, they leave scratches that will lead to leaks.

3. Step-by-step instructions for installing Xiaomi nozzle

Now, let's get to the process itself. Consider the universal algorithm for most models (e.g., the Mijia Smart Faucet):

Step 1. Dismantling the old nozzle (aerator)

1. Cover the water on the riser or under the sink.
2. Wrap the faucet with a cloth so as not to scratch.
3. Carefully unscrew the old counterclockwise nozzle with a movable key. If it's "sticky," use it. WD-40 or heat the faucet with a hairdryer (not higher than 60)°C!).

Step 2: Cleaning and preparation of the thread

• Remove the remnants of the old FUM tape or gasket.
• Rub the carving with alcohol or vinegar for degreasing.
• Apply 1-2 turns of FUM tape clockwise (if there is no silicone gasket in the kit).

Step 3: Installation of a new nozzle

1. Check that the nozzle has a gasket (usually black or blue).
2. Carefully screw the nozzle clockwise manually to the point.
3. Keep the sliding key (do not overdo it – enough) 1/4 turn-over!).

Step 4: Checking the leakage

• Open the water and check if there are any leaks.
• If water drips from under the nozzle, pull it up a little with a key.
• For smart models: connect the nozzle to the Mi Home according to the instructions (usually you need to press the button on the case and select the device in the application).

💡

If the nozzle is not screwed in to the end, do not apply force! most likely, the thread does not match. Use an adapter (for example, with a scalp). G1/2 on G3/4), which can be purchased at any of the plumbing shops.

4 Common Mistakes and How to Avoid Them

Even when following the instructions, users often face problems, and here are the most common ones:

Problem 1: The nozzle leaks after installation

• 🔹 Cause: Damaged gasket or insufficient FUM tape.
• 🔧 Solution: Unscrew the nozzle and check the integrity of the gasket. Add 1-2 turns of FUM tape or replace the gasket with a new one. Tighten the nozzle with a key (but don't drag it over!).

Problem 2: The nozzle is not screwed or is tight

• 🔹 Cause: Carving mismatch or pollution.
• 🔧 Solution: Check the thread markings on the tap and nozzle. Clean the lime plaque thread. Use the adapter if necessary.

Problem 3: Smart nozzle doesn't connect to Wi-Fi

• 🔹 Reason: Weak signal or incorrect router settings.
• 🔧 Solution: Bring the router closer to the faucet or use a repeater. In the router settings, turn off 5 GHz - many Xiaomi devices only work on 2.4 GHz. Reset the nozzle (usually holding the button 5-10 seconds).

⚠️ Warning: If the water pressure has decreased noticeably after installation, check if the filters in the nozzle are clogged, V-RFM01) You need to change the cartridges regularly, otherwise the pressure will fall.

5. Features of installing smart nozzles (with connection to Mi Home)

Xiaomi smart nozzles (for example, Mijia Smart Faucet or Viomi) V-RFM01) It takes a few extra steps to adjust. This is what you do after you mechanically install it:

Step 1: Installation of the application

• Download Mi Home (Android/iOS) and register.
• Choose China Mainland (many nozzles are not visible in other regions!).

Step 3: Configure functions

• 📊 Monitoring water flow: turn on in the device settings.
• 🔥 Backlight: Choose color and mode (e.g. blue for cold water, red for hot water, and color for hot water).
• 🛠 Maintenance: Set up filter replacement reminders (for Viomi models).

If the nozzle is not determined, try:

• 🔄 Reboot the device (turn off/on the water for 10 seconds).
• 📶 Switch your smartphone to mobile Internet (sometimes helps with problems with the router).
• 🔧 Update the firmware nozzle through Mi Home.

💡

Xiaomi smart nozzles work only with routers at 2.4 GHz. If your Wi-Fi is running on 5 GHz, create a separate network for devices or change the router settings.

6. Maintenance and care: how to extend the life of the nozzle

To make the nozzle last longer, follow these recommendations:

• 🧼 Cleaning: Once a month, wash the lime plaque mesh (use vinegar or citric acid).
• 🔧 Change silicone seals every 6-12 months (they lose elasticity).
• 💧 Pressure: If the water pressure exceeds 6 bar, install a gearbox - this will protect the nozzle from breakage.
• ⚡ Power: For backlit models, use only original power supplies (non-Chinese counterparts can burn circuitry).

For filter nozzles (Viomi, Aqara):

• 🔄 Change the cartridges every 3-6 months (depending on the hardness of the water).
• 📅 Keep a record of water consumption in Mi Home – the application will remind you of the replacement.
• 🚫 Do not use boiling water to flush filters – it destroys the membranes.
