Kitchen water problems we fix
Better-tasting water at your kitchen sink: we help Downers Grove homeowners choose between carbon filters and reverse osmosis, then install the system, the faucet and the drain connection.
Lead service line not yet replaced
While Downers Grove replaces lead service lines, we install lead-certified filtration for drinking and cooking water.
Cloudy ice and spotted glasses
Hard-water spots on glassware and cloudy ice cubes improve with reverse osmosis at the sink.
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.
Chlorine taste and smell
Tap water that smells like a swimming pool is common with treated municipal water. A carbon stage removes chlorine taste and odor.
Worried about lead
Older plumbing and service lines can add lead. We install systems certified for lead reduction under NSF/ANSI 53 or 58.
Refrigerator filter not enough
We can connect the filter to your fridge's ice maker and water dispenser too.
What the install includes
- Water checkA look at your water source and plumbing so the system matches what is actually in your water.
- 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.
- Whole-house optionsIf testing shows hardness or sediment, we can add a whole-house filter or softener alongside the kitchen system.
Models, parts and fittings
NSF/ANSI certificationsCheck the certification against what you want removed — not just the marketing claim.

The result: a polished chrome filtered-water faucet next to the main faucet and a two-canister carbon filter system with a shut-off valve under the sink. On site this meant drain connection for RO, refrigerator line, plus whole-house options.

Under-Sink Water Filtration questions from Downers Grove homeowners
Is Lake Michigan water already safe?
It meets federal drinking-water standards when it leaves the plant. A kitchen filter deals with taste, chloramine and what your own pipes add.
How do I find out if I have a lead service line?
Your town's service line inventory shows the material; we can also look at the pipe where it enters the house.
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.
How often do filters need changing?
Plan on new carbon cartridges once or twice a year and an RO membrane every few years — sooner with heavy use.
Does RO waste water?
Yes, some water goes to drain. Newer efficient systems reduce that ratio a lot.
Downers Grove building permit for kitchen water filtration: where do I apply?
Permits go through Community Development Department, Building Division (https://cvportal.downers.us), phone 630-434-5515. When your scope needs one, we prepare the application and schedule the inspections.
Does Downers Grove have lead service lines?
2026 inventory: 17,063 total service lines; 1,285 lead. A filter certified for lead reduction is a sensible step until your line is confirmed or replaced.
Downers Grove water: how does it affect kitchen water filtration?
Downers Grove's water source: Lake Michigan water purchased from the City of Chicago via the DuPage Water Commission. That decides which filter stages make sense.
