Hard well water
Scale on fixtures and orange stains point to hardness and iron. We treat those first so the drinking filter lasts.

Kitchen water problems we fix
We install under-sink water filters and reverse osmosis systems in Lake Zurich kitchens — a dedicated filtered-water faucet, a certified system matched to your water and a drain connection done right.
Worried about lead
If you're unsure about your pipes, a lead-certified filter adds a layer of protection while you check.
Don't want to drill the counter
Some systems connect to your existing faucet or use the sprayer hole, so no new hole is needed.
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
Under-sink filtration gives you a steady flow instead of refilling a pitcher all day.
Buying bottled water
Stop hauling water bottles — a filtered faucet gives you clean water on demand.
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.
Refrigerator filter not enough
One under-sink system can supply the sink tap and the fridge, so you change one set of cartridges instead of two.
What the install includes
- Water checkA look at your water source and plumbing so the system matches what is actually in your water.
- 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.
- 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.
- Whole-house optionsPoint-of-use filtration at the sink, plus whole-house treatment when your water needs it.
What to pick before the install
Remineralization stageAdds back minerals after RO for a better taste.
Under-sink carbon filterImproves taste and odor; many models are certified for lead. Compact and simple.

DetailBefore and after: a 1980s two-story in Lake Zurich
This one is a 1980s two-story in Lake Zurich. What we started with: solid-surface integrated sink. What bothered the owners most: tap water that didn't taste right. After: 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. Work included system selection, dedicated faucet, plus refrigerator line.

The site: a two-story colonial from the 1990s in Palatine. What we started with: white double sink. What bothered the owners most: tap water that didn't taste right. The result: a satin brass filtered-water faucet next to the main faucet and a tankless reverse osmosis unit with a small remineralization cartridge under the sink. The job covered system selection, dedicated faucet, plus whole-house options.

A 1980s two-story near Green Knolls, a typical kitchen for Buffalo Grove. The kitchen as it was: white double sink. The reason for the call: tap water that didn't taste right. After: slim filtered-water faucet next to the main faucet. On site this meant water check, system selection, plus drain connection for RO.

Under-Sink Water Filtration questions from Lake Zurich 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.
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.
Reverse osmosis or carbon filter?
If taste is the issue, carbon. For the broadest protection, RO.
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.
Whole-house filter or under-sink?
It depends on the problem: taste and contaminants — under-sink; scale and sediment — whole-house.
Is Lake Zurich water hard, and does it matter for kitchen water filtration?
Lake Zurich's water source: Deep underground aquifers (wells), chlorinated; ion-exchange treatment; reported hardness is 6-8 grains per gallon (reduced from 14-18 grains per gallon by ion-exchange systems installed 2003-2009). That decides which filter stages make sense.
Does Lake Zurich have lead service lines?
Village publishes a Water Service Line Material Inventory and 2025 Lead Tap Sampling Data (documents not read; counts not captured). A filter certified for lead reduction is a sensible step until your line is confirmed or replaced.
Do I need a Lake Zurich-registered contractor for kitchen water filtration?
All contractors and subcontractors must register with the Village before work: form, $120 annual fee (Illinois-licensed plumbers exempt), signed $10,000 surety bond. Village pages show differing fee amounts ($110/$120/$125). We take care of that before work starts.
Does Lake Zurich require a licensed plumber for kitchen water filtration?
Plumbing contractors submit state registrations (055 & 058) and a letter of intent with each permit application. Our plumbing connections are made by licensed plumbers.
Lake Zurich building permit for kitchen water filtration: where do I apply?
