Kitchen water problems we fix
Better-tasting water at your kitchen sink: we help Warrenville homeowners choose between carbon filters and reverse osmosis, then install the system, the faucet and the drain connection.
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.
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.
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
If you're unsure about your pipes, a lead-certified filter adds a layer of protection while you check.
PFAS and other contaminants
Many people now ask about PFAS. Look for systems certified to reduce PFOA/PFOS; reverse osmosis covers the widest range.
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.
What we hook up and check
- Water checkWe review your utility's water report and look at your pipes before recommending a system.
- Under-sink installationThe filter housing mounted under the sink with a shut-off valve and leak-free fittings.
- Drain connection for RORO systems need a drain connection — installed correctly to prevent backflow.
- Refrigerator lineOptional line to the fridge so ice and water come from the same filter.
- Filter change planReminders and easy cartridge swaps so the filter keeps working.
- Whole-house optionsIf testing shows hardness or sediment, we can add a whole-house filter or softener alongside the kitchen system.
Options to choose from
Reverse osmosisBroadest reduction of contaminants, including lead, PFAS and dissolved minerals. Needs a drain connection.
Tankless ROCompact RO systems without a storage tank — they fit tight sink cabinets.
Under-sink carbon filterA one- or two-stage carbon system for great-tasting water.
NSF/ANSI certificationsCheck the certification against what you want removed — not just the marketing claim.

Under-Sink Water Filtration questions from Warrenville homeowners
Do I need a softener with a well?
Often yes — hard water and iron shorten filter life. A softener or pre-filter in front protects the drinking system.
Does RO waste water?
Every RO system rinses its membrane to the drain. Current high-efficiency units send far less water down the drain than older designs.
Will a filter lower my water pressure?
No — the filtered faucet is separate from your main faucet.
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.
How often do filters need changing?
Carbon cartridges usually every 6–12 months; RO membranes every 2–3 years, depending on use and water.

Permits go through Community Development Department, Building Division, phone 630-393-9050. When your scope needs one, we prepare the application and schedule the inspections.
