What do you need help with?

What Troy homeowners usually call us about

• Drinking water that tastes or smells “off,” even though it comes from the city
• Coffee, tea, or ice cubes that never taste quite right
• Buying cases of bottled water or paying for jug delivery every month
• An RO that came with the house and has no record of when the filters were last changed
• An older system that drips, runs slowly, or makes noise under the sink

A local note: Troy’s tap water comes from the Great Lakes Water Authority. According to the City of Troy 2025 Water Report, most of it is treated at GLWA’s Lake Huron plant in Port Huron, with a small share from the Northeast plant in Detroit, and the city maintains the water mains that carry it to your service line. Because the water is already treated before it reaches you, most Troy RO projects are about taste, convenience, and drinking-water quality at the tap rather than fixing an untreated supply. What happens in your own plumbing still varies from house to house, which is why we look at your water before recommending anything.

How we work

1. Test. We look at your water and the space where the system will go, whether that is under the kitchen sink or in the basement below it.
2. Identify. We sort out which concerns an RO can help with and which ones, like hardness or a whole-house odor, need a different step.
3. Recommend. You get a straight answer: a new RO, service on the one you already own, or a different solution first.
4. Install & maintain. We install and flush the system, show you how it works, and set a filter-change schedule so it keeps performing.

Reverse Osmosis Installation & Service in Troy

Most systems we install in Troy are under-sink units that feed a dedicated drinking-water faucet beside the main kitchen faucet. When the cabinet is tight, a basement-mounted system with a line run up to the kitchen can work, like the install shown above. We connect the drain and storage tank, check for leaks, and flush the system before you use it.

We also set up RO for wet bars, second kitchens, and light commercial spaces such as offices and break rooms along the Big Beaver corridor and elsewhere in Troy. If a project needs plumbing beyond a normal hookup, we coordinate with our partner, Putman & Son’s Plumbing.

Already have an RO? Typical service work includes:

• Pre-filter, carbon, and post-filter replacement
• Membrane replacement when production or taste drops off
• Storage tank, faucet, and check-valve problems
• Leaks, low flow, and drain-line issues

If a repair would cost close to a new system, we will show you both options. For general timing, see how often to service a reverse osmosis system.

Is RO the right fix, or do you need something else?

An under-sink RO treats the water you drink and cook with at one faucet. It does not soften the whole house or take care of a smell in the shower. If testing shows hardness, a water softener for your Troy home may be the better first step, with softener salt delivery to keep it running. If the concern is at every tap, whole-house filtration may make more sense. Our article on whole-house filtration vs under-sink RO explains the difference.

Reverse Osmosis FAQs for Troy Homeowners

Do I need a reverse osmosis system if I am on Troy city water?

You do not need one, but many people want one. City water is treated before it reaches your home, and an RO is about improving the water you drink and cook with at the tap. If you like the taste of your water and do not buy bottled water, you may not need it. If you do, an under-sink RO is a practical upgrade, and we will tell you honestly which camp you are in.

What does a reverse osmosis system reduce?

RO combines a membrane with sediment and carbon stages to reduce many dissolved impurities and improve taste and odor. What a specific system reduces depends on the unit, the membrane, and your water. We go over what your test shows and what the recommended system is designed to handle.

How long does an RO installation take?

A typical under-sink installation is usually finished in a single visit. A basement-mounted setup, an added line to a refrigerator, or a tight cabinet can take longer. We give you a realistic time when we schedule.

How often do RO filters and membranes need to be changed?

Pre-filters and carbon stages are changed on a regular schedule, and the membrane lasts longer. The right timing depends on your water and how much you use the system. We set a schedule at install, and you can call 248-651-5238 when a change is due.

How much does a reverse osmosis system cost in Troy?

It depends on the system, where it will be mounted, whether any pre-treatment is needed, and whether an old unit is coming out. After we look at your water and the space, we give you a real installed price instead of a range from the internet.

Can you service an RO system you did not install?

Yes. We work on reverse osmosis systems from many manufacturers. If yours is worth keeping, we will service it. If replacing it makes more sense, we will explain why.

Do you install RO systems for Troy offices and businesses?

Yes, for light commercial uses such as offices, break rooms, and small food-service spaces where an RO setup fits. Larger projects are reviewed case by case. Visit our commercial water treatment page or call us to talk it through.
