Kitchen water problems we fix

An under-sink filter in Mount Prospect gives you clean drinking and cooking water straight from a dedicated faucet. We match the system to your water source and pipes and install it in one visit.

Chloramine in Lake Michigan water

Many Lake Michigan suppliers disinfect with chloramine, which ordinary carbon removes poorly. We use catalytic carbon rated for it.

Pitcher filter is too slow

Waiting for a pitcher to refill gets old. An under-sink system delivers filtered water as fast as you need it.

PFAS and other contaminants

For PFAS and other emerging contaminants, we install systems with the matching NSF/ANSI certification.

Buying bottled water

Stop hauling water bottles — a filtered faucet gives you clean water on demand.

Cloudy ice and spotted glasses

White film on glasses and cloudy ice come from dissolved minerals; reverse osmosis takes most of them out.

Hard water and scale

Calcium and magnesium leave scale on kettles and faucets. Reverse osmosis removes most of it from drinking water; a softener treats the whole house.

Don't want to drill the counter

If you'd rather not drill stone, we choose a system that works with your existing faucet.

Worried about lead

If you're unsure about your pipes, a lead-certified filter adds a layer of protection while you check.

Under-Sink Water Filtration questions from Mount Prospect homeowners

Is Lake Michigan water already safe?
Your utility treats the water to federal standards. Filtering at the sink addresses taste and anything picked up in your home's pipes.
Can you drill a faucet hole in my quartz or granite?
Yes — we drill stone counters with a diamond core bit, or use an existing sprayer or soap hole.
Whole-house filter or under-sink?
Under-sink treats drinking and cooking water; whole-house protects every tap and appliance. Many homes need only the first.
Do I need a plumber to install an under-sink filter?
For a basic filter, maybe not. For RO with a drain and a dedicated faucet, we recommend a professional install.
Reverse osmosis or carbon filter?
Carbon is enough for taste and chlorine, and many models are lead-certified. RO removes far more, including dissolved minerals and PFAS.
Mount Prospect plumbing code: who can do the plumbing for kitchen water filtration?
Plumbing contractors need the Village contractor license plus state license. State plumbing code requires a state-licensed plumber in multi-family buildings. Our plumbing connections are made by licensed plumbers.
Is Mount Prospect water hard, and does it matter for kitchen water filtration?
Mount Prospect's water source: Lake Michigan water treated by the City of Chicago (Jardine plant) and delivered via the Northwest Suburban Municipal Joint Action Water Agency (NSMJAWA); backup from Northwest Water Commission. Some areas are served by Illinois American Water instead. That decides which filter stages make sense.
Do I need a Mount Prospect-registered contractor for kitchen water filtration?
A Contractor's License is required for general contractors (and listed trades); $200, valid one year, applied for through the online portal. We take care of that before work starts.
Can you do kitchen water filtration in a Mount Prospect condo?
Associations usually set rules for work hours, elevators, deliveries and insurance, and many require approval for plumbing, electrical or structural changes. We provide the certificate of insurance and follow the building's rules.
What is Mount Prospect doing about lead water lines?
Village has completed its required lead service line inventory, available on the Village website (2025 report). A filter certified for lead reduction is a sensible step until your line is confirmed or replaced.
Do I need a permit for kitchen water filtration in Mount Prospect?
It depends on the scope. Mount Prospect's rule in short: Kitchen remodels need a permit and a code review (about 10 business days). We handle the permit when one is needed with Community Development Department - Building & Inspection Services.
