Kitchen water problems we fix
We install under-sink water filters and reverse osmosis systems in St. Charles kitchens — a dedicated filtered-water faucet, a certified system matched to your water and a drain connection done right.
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
PFAS questions come up on almost every call now. Reverse osmosis and certified carbon blocks reduce PFOA and PFOS — check the certificate, not the box.
Hard water and scale
White crust on the faucet and kettle is mineral buildup. RO at the sink handles drinking water; a softener protects the rest of the plumbing.
Worried about lead
Lead usually comes from pipes and fittings, not the treatment plant. A system certified to NSF/ANSI 53 or 58 for lead reduction protects the water you drink.
Refrigerator filter not enough
We can connect the filter to your fridge's ice maker and water dispenser too.
Buying bottled water
Cases of bottled water are expensive and heavy. A filtered tap at the sink costs far less per gallon.
Cloudy ice and spotted glasses
White film on glasses and cloudy ice come from dissolved minerals; reverse osmosis takes most of them out.
What the install includes
- Water checkWe review your utility's water report and look at your pipes before recommending a system.
- System selectionCarbon, catalytic carbon or reverse osmosis — matched to taste, lead or PFAS concerns.
- Dedicated faucetWe use the sprayer or soap hole or drill a new faucet hole, including in stone.
- Under-sink installationMounting, supply connection and shut-off valve so service is easy later.
- Drain connection for ROA proper drain saddle or air gap so reverse osmosis drains to code.
- Refrigerator lineWe can run filtered water to your ice maker and dispenser.
What to pick before the install
NSF/ANSI certifications42 for taste and chlorine, 53 for health contaminants like lead, 58 for RO, 401 for emerging contaminants.
Reverse osmosisThe most thorough filtration; includes a membrane, storage tank or tankless pump.
Remineralization stageAn optional final stage that improves the taste of RO water.
Tankless ROCompact RO systems without a storage tank — they fit tight sink cabinets.

Under-Sink Water Filtration questions from St. Charles homeowners
How do I find out if I have a lead service line?
Look up your address in the utility's service line inventory or check the pipe at your water meter; we can help you read it.
How often do filters need changing?
Most cartridges last 6–12 months. We'll set a reminder schedule.
Do I need a plumber to install an under-sink filter?
Simple carbon filters are often DIY. Reverse osmosis needs a drain connection and sometimes a new faucet hole, which is where a pro helps.
Is reverse osmosis water safe to drink every day?
Yes — RO water is widely used for drinking. A remineralizing stage is optional.
Can you drill a faucet hole in my quartz or granite?
Yes. A diamond core bit cuts a clean hole in stone, or we reuse a sprayer, soap dispenser or air-gap hole.
Do I need a St. Charles-registered contractor for kitchen water filtration?
No registration fee; contractor requirements (general contractor certificate of insurance, with City as certificate holder) must be submitted before a permit is issued. We take care of that before work starts.
Does St. Charles require a licensed plumber for kitchen water filtration?
Plumbing contractors must hold an Illinois 055 license; provide copy of photo ID license. Our plumbing connections are made by licensed plumbers.
What is St. Charles doing about lead water lines?
The City is inventorying water service lines under the Illinois Lead Service Line Replacement & Notification Act and finalizing a long-term lead line replacement plan. A filter certified for lead reduction is a sensible step until your line is confirmed or replaced.
