How Does Automatic Water Tap Work?

Technology has brought into existence automatic or touchless water taps. By iWater deluxe review, these water systems are gaining popularity in the recent past. Several homeowners find them convenient, and they are busy installing them in their kitchens and bathrooms.

These systems have components that monitor the water flowing process. Power supply and an electrical magnet also make the process effortless. But how does automatic water tap work? Get it right from this article.

How Does Automatic Water Tap Work?



A lot of innovation and invention are taking place due to technological advancements in this new millennium. Today, we have automatic water taps that release water with just a swipe of the hand. They emerge great innovations, espec

ially during this pandemic period. Automatic water taps allow people to stay germs-free anytime and in any situation. But how does automatic water tap work?

These systems seem to use simple technology to work. However, they have inner workings that are complicated in a way. The inner components of these systems need regular monitoring to maintain them run efficiently. You will get more ideas about an automatic tap by reading the iWater deluxe review.


Automatic water taps have vital components that enable them to function on command. They include the sensor, spout, solenoid-controlled valve, and power source. With just a swipe of the hand by the tap, the sensor detects it. The tap immediately turns on and back when you remove the hands. Let’s look at the automatic water tap’s components to get it right now this machine works.


The sensor of the automatic water tap is located at the base or bottom part of the spout. Its primary role is to detect the hands to turn the system on and off. Immediately you swipe the hands over it, the system turns on to allow water to flow out. 

Likewise, upon withdrawal of your hand, the system closes up. Sensors of water taps use infrared light to detect. It sends signals to turn the valve on. However, not all sensors use infrared light to detect a hand, and others use ultrasonic fields for detection. 

Solenoid Valve

The solenoid valve of the water taps controls the opening and closing of the tap. This component has an electromagnetic part responsible for pushing and pulling with electric polarity changes. There is also a rubber made disk that controls the flow of water. 


Most automatic water taps have brass-made spouts. However, there are cheaper options made of zinc. Nowadays, others are plated using nickel or chrome for added appearance and durability. You choose the type you need depending on your washrooms or kitchen design and your preferred shape. The spout houses other working components. 

Power Source

Automatic water taps depend on electric current to run. Some use low voltage currents from AC transformers and others draw current from dry cells. The best part of battery-powered systems is using solenoid valves that don’t require additional power to function. 

Troubleshooting Automatic Water Taps

Sometimes your automatic water tap can develop problems. Most people assume that water tap problems lie at the solenoid valves alone. However, this isn’t the case, as other components might also fail at times. There is a need for regular checkups of the entire system to function efficiently. 

There are a lot of ways you can detect problems in your automatic water tap. Among the ways to detect problems is a small amount of water flows out of the tap and leakages in hoses. In case a small amount of water flows out, then possibly there is a problem with the aerator. This can also signify a clogged aerator. 

To fix the problem:

  1. Remove the aerator to see whether there is something stuck in it.
  2. Soak it in vinegar and fix it back. If the problem persists, check for a possible clog in the hose.
  3. Check whether for possible issues with the cartridge.
  4. Check whether it’s broken or the cartridge nut is secure. 

Lastly, look for the rubber seals and washers for possible damages. In case of leaks with the inlet hose, then ensure you tighten it well. If the problem persists, get out everything and clean them for any possible blockage within the system.

Problems with the Solenoid Valve Battery 

After proof that other plumbing components are in good condition, the next possible problem to consider is the battery. If you note that your water tap’s LED light is flashing, then possibly this is an indication of a low battery. For normal and continuous functioning of the system, replace the batteries once they die or get depleted.

Problems with the Solenoid Valve

The third thing that might drip in your mind after you still experience problems is a possible faulty solenoid valve. Dirty solenoid valves can make the entire system stop working effectively. For this, you will turn off the water and disassemble the valve carefully. Clean the valve and fix it to its respective place. In case you don’t solve your problem after testing, then there is a need to replace the valve. 

Cases When the System Doesn’t Turn off Automatically

Your automatic water tap should turn off automatically if it’s in good condition. If it fails to do so, then check for possible untightened components. Check the parts and connection to ensure it is tightly secured. 


So, how does an automatic water tap work? Automatic water taps have four components that enable it to function. However, these taps, at times, develop problems. The problems might happen due to a faulty component, clogged parts, or even a part not tightly secured. If an issue arises with your tap, always consider fixing it before the situation worsens. If you lack the idea of carrying out regular maintenance exercises, ensure you hire an expert to monitor your tap. This way, you will get long term effective service from your automatic water tap.
