Quick answer: Touchless faucets are convenient and hygienic, but they rely on an electronic valve under the sink with a small strainer that can clog on sediment-heavy well water, sometimes needing service every couple of months. If you are on a New Hampshire well, pair a touchless faucet with a whole-home sediment filter to protect it, and ask your plumber whether the model's strainer is easy to clean before you buy.
Touchless faucets have gone from a restaurant novelty to something plenty of homeowners want in their own kitchens, and it is easy to see why. You wave a hand and the water comes on, with no handle to grab when your fingers are covered in raw chicken or bread dough.
We install and service a lot of faucets across the Manchester area, and touchless models are one of those upgrades where a little knowledge up front saves our Clients real money later. Here is what we tell people who ask us about them, especially if their home runs on well water.
What is a touchless faucet?
A touchless faucet, sometimes called a hands-free or motion-sensor faucet, turns the water on and off when it senses movement near the spout. Pass a hand or a pot underneath and the water flows. Most models still have a manual handle for setting temperature and flow, with the sensor handling the on and off.
Why homeowners like them
For a busy kitchen, a touchless faucet just makes daily tasks smoother. You can fill a pot, rinse a plate, or wash up mid-recipe without fumbling for the handle. It feels modern, and once people get used to one, they rarely want to go back.
The hygiene benefit
Because you are not touching the faucet with dirty hands and then touching it again once they are clean, a touchless faucet cuts down on the germs and grime that collect on a handle. That is a real plus during cold and flu season, or any time you are handling raw meat.
The water-saving benefit
Since the water shuts off the instant you step away, a touchless faucet can quietly trim how much water you waste over the course of a year. It is a small thing on any single use, but it adds up.
How a touchless faucet works
To understand where these faucets run into trouble, it helps to know what is happening under the sink.
The sensor and the solenoid valve
A traditional faucet is simple. The handle physically opens and closes a valve, and nothing about it is electronic. A touchless faucet is different. The sensor at the top signals a small electronic valve mounted under the sink, called a solenoid, and that valve is what actually starts and stops the water every time you trigger the sensor. It runs on power, usually a battery pack under the sink or a small plug-in transformer.
The strainer that protects the valve
Because the solenoid contains electronics and precise moving parts, the manufacturer protects it with a tiny strainer or screen on the inlet side. Its job is to catch debris before it reaches the valve. On clean, well-filtered water, that strainer does its job for years and nobody ever thinks about it. The trouble starts when the water feeding the faucet is not clean.
The New Hampshire well water problem
Why well water is different
A large share of New Hampshire homes draw from a private well, and well water tends to carry more sediment than treated municipal water. Fine sand, grit, and mineral particles ride along in the water and reach every fixture in the house.
What happens when the strainer clogs
On a touchless faucet, that sediment collects in the little strainer protecting the solenoid valve. Over time the strainer clogs, the flow drops, and eventually the faucet stops working right. Here is the part that catches people off guard: on some models you cannot just pop the strainer out and rinse it. The whole valve assembly has to come apart to clean it. A homeowner who loves the faucet can end up calling a plumber every couple of months just to keep it running, and a service call like that can run around $300 each time. What started as a convenient upgrade turns into a recurring bill.
A real example from our own work
We have seen this firsthand. We once installed a touchless faucet for a customer that gave so much trouble on their water that we ended up pulling it back out. The faucet was not a bad product on paper. It was that the water feeding it was working against it, and the design made the strainer nearly impossible to service.
Not every touchless faucet is built the same
This is not a reason to write off touchless faucets. It is a reason to choose carefully. Even among quality brands, the way a faucet handles this exact problem varies. Kohler, for example, makes some genuinely good touchless faucets, and Kohler is a brand we like and install often. But the question that matters most for a well water home is not the badge on the box. It is whether the strainer on the solenoid valve can be cleaned easily, or whether servicing it means taking the whole assembly apart.
That detail almost never shows up in a product description or an online review, which is why it helps to ask a plumber who has actually worked on these faucets before you buy. The right model for a home on city water can be the wrong choice for a home on a sediment-heavy well.
How to tell if your water carries too much sediment
You do not need lab equipment to get a rough sense of your sediment situation. A few everyday signs point to it:
- Grit or fine sand collecting in your faucet aerators when you unscrew them to clean them.
- Water that looks cloudy or tinted, especially right after the pump runs.
- Fixtures, screens, and appliance filters that clog more often than they should.
- A private well, particularly a shallow one or one that pulls more sediment after heavy rain.
If two or three of those sound familiar, sediment is very likely reaching your fixtures, and a touchless faucet installed without protection is going to struggle. The surest way to know is to have your water tested, which also flags other common New Hampshire well issues like hardness and iron.
The fix: filter first
The good news is that this whole problem is preventable, and the solution protects far more than one faucet.
Start with a sediment filter
The core step is a good sediment filter. A whole-home sediment filter catches sand and grit before it ever reaches your faucets, appliances, and fixtures. That keeps the solenoid valve in a touchless faucet clean, along with your aerators, your water heater, and your dishwasher. It is one of the highest-value, lowest-drama upgrades a well water home can make.
When to add softening or reverse osmosis
Depending on what a water test turns up, a sediment filter is often just the starting point. Hard water may call for a water softener, and homeowners who want cleaner drinking water at the tap often add reverse osmosis at the kitchen sink. These pieces work together, and the right combination comes down to your specific water, which is what our water quality services are built around. The goal is not to sell you every filter under the sun, it is to protect the fixtures you are investing in.
What to do if your touchless faucet is already acting up
If you already have a touchless faucet and the flow has dropped off, it is stuttering, or it has stopped responding, do not assume the faucet is junk. More often than not, the culprit is a clogged strainer or a sediment issue upstream, not a failed faucet. A plumber can confirm what is going on, clean or service the valve, and talk through filtration so you are not back in the same spot in a few months. In some cases the smarter long-term move is switching to a model better suited to your water, but that is a last resort, not a first step.
For many homes, yes. They are convenient, more hygienic, and can save a bit of water. The main caveat is water quality, which is very manageable with the right filtration.
Most battery-powered models keep working normally in an outage, since they do not rely on your home's power. Models wired to a transformer may not, though many include a manual override. It is worth checking before you buy if outages are common where you live.
It can, as long as you protect it. Well water's sediment is what causes most touchless faucet headaches, so pairing one with a whole-home sediment filter is the key to a faucet that lasts.
Yes. We are happy to install a fixture you picked out yourself. Just note that a faucet we did not supply will not carry our own WOW warranty, though we will still make sure it is installed correctly.
Grit in your aerators, cloudy water, and fixtures that clog often are all signs. A water test gives you the clear answer and shows what else might be in your water.
Almost always because sediment in the water is collecting in the strainer that protects the electronic valve. A sediment filter upstream solves the root cause rather than treating it over and over.
It depends on the model. Some make the strainer and valve easy to reach and service, while others require taking the whole assembly apart. This is exactly why the serviceability of a model matters as much as its looks.
