What is a Touchless Faucet?

A touchless faucet, also known as a motion-activated faucet, is a novel style of regular kitchen faucet. It can be operated by just waving at the faucet’s sensor. Considering the faucet type, the sensor is located on the top or around the handle’s location.

A touchless faucet is functioning according to the inputs of the motion sensor.

Along with an entirely touchless faucet, you may choose basic touch-on faucets. Such touch faucets include sensors on the handle or the spout of the faucet, allowing you to initiate water flow by tapping the faucet.

While such faucets are operable by the flick of a finger, hand, or forearm, they also provide manual options.

Touchless faucets and how they work are a technical wonder that may significantly reduce germ transmission and provide a continuous flow of clean water with a finger sweep. In every case, touchless faucets enable you to remove germs from raw material or disinfect your hands. 

While the technology behind the touchless faucet can seem pretty simple, it has intricated inner system that occasionally needs TLC to maintain itself in excellent working condition.

Four critical components ensure that a touchless or automated faucet operates appropriately. These include a sensor, a power supply, a spout, and finally, the setup’s most critical component, a solenoid-controlled valve.

The faucet activates the moment the sensor recognizes a hand. When the hand is withdrawn from the faucet, it automatically shuts off. This is one aspect of the touchless faucet’s overall operation. 

To better understand how a faucet operates, it’s first essential to grasp how each part works independently and combinedly. This article only focuses on a faucet’s power supply or battery.

What is a Power Source of a Touchless Faucet?

Touchless faucets obtain their electricity in a variety of methods. Based on the mode, low-voltage electricity from a dry-cell battery or a transformer in the fixture’s neck or back can power up the fixture.

Electricity is required to power up the sensor and activate the water valve. A solenoid valve is used in a battery-powered faucet. This remains open until an electric power current forces them back into the closed position.

That is a frequently asked question. Depending on a faucet’s build quality or capacity, its battery can endure different periods. Various brands come with different suggested lifetimes. Most of the time, faucet batteries sustain at least tens of thousands of hours or, on average, can last up to 2-5 years.

I interviewed one of the users of touchless faucets about her experience with the battery support. She likes the type of faucets this article deals with. As a result, I asked how long she had had it and presented her with a link to the top-rated touchless faucets available.

As it turns out, she has been using her faucet for around three years. And although I am unable to provide an exact figure, I can say that she has utilized around a thousand distinct brands. She has gone to different department shops, purchased nearly a dozen faucets, and seen that the battery support depends on the manufacturing companies of the faucets.

Therefore, the question remains, “Do people need a new battery?” Obviously not. What important is the supportability of the battery? How long are they effective?

If you pick a reputable brand, you must think before buying new batteries very often. However, if you use a touchless shower more frequently than more than twice per year, you may want to consider changing the battery. It is not a significant expenditure. Indeed, you might call it a no-brainer way idea.

This is because replacing a battery can be costly most of the time. It is much more cost-effective to get a new faucet. Usually, touchless faucets endure between 5 and 10 years. 

Additionally, if the water in a house becomes excessively unclean, it may stay far longer. However, you may have to replace the battery soon if you aren’t cautious.

A less popular but more effective method of removing your old battery is to disassemble the faucet. All the components are available for sale on eBay. Alternatively, you might contact sellers and have those parts dismantled for you. It is a somewhat more difficult task than disassembling the shower.

How to be More Careful to Ensure Elongated Battery Life?

You must ensure that you have all the necessary components and function excellently. Caution should be used while dismantling the equipment. To test the cable, do not yank on it, or this might cause damage to the fuse and the battery.

Additionally, take care so you don’t damage the battery while scraping harshly or over-twisting the cables. The battery can get damaged before it reaches the point of reuse.

If you discover that your battery is permanently damaged, do not despair. There are steps you can take. First, you may replace the damaged battery or add a jumper to extend its life. If you’re unsure how to perform these activities, a wealth of information is available on different sites.

Additionally, you may try replacing the battery many times. This will not put the battery back to life. It will charge the battery. Also, a little boost from your vehicle’s battery charging will suffice.

Alternatively, you may change the batteries. They are available at most local hardware stores, or one can purchase a generic substitute on eBay. Certain batteries have a longer life than others. Bear this in mind while making a purchase.

If used every day, the battery of a faucet will last around two years. The battery will last longer when used less regularly, but it should endure a year even with regular usage. Although the use period is lengthy, batteries are preferable to nothing else. 

The average touchless faucet is between one and two years. Don’t be disheartened if it continues for that length of time.


In conclusion, touchless faucets can last several years, depending on the quality and frequency of use. Mostly it will be 2 to 4 years.

According to my personal experience, I have a touchless faucet in my kitchen. Usually, I use it many times a day but didn’t replace the battery for nearly two years.
