Kitchen water problems we fix
An under-sink filter in Oak Brook 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.
Hard well water
Hard well water scales faucets and fixtures. A softener ahead of the filter protects the system and your appliances.
Worried about lead
Older plumbing and service lines can add lead. We install systems certified for lead reduction under NSF/ANSI 53 or 58.
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.
Refrigerator filter not enough
Fridge filters are small and often expensive. An under-sink system can feed both your sink tap and your fridge.
Pitcher filter is too slow
Pitchers hold a few cups and the cartridge clogs fast. Under the sink you get a full-flow filtered tap that is always ready.
Chlorine taste and smell
If your water tastes like chlorine, an activated carbon filter makes it taste clean for drinking and coffee.
PFAS and other contaminants
Many people now ask about PFAS. Look for systems certified to reduce PFOA/PFOS; reverse osmosis covers the widest range.

Under-Sink Water Filtration questions from Oak Brook homeowners
Is Lake Michigan water already safe?
Treated Lake Michigan water meets federal standards, but taste, chloramine and household plumbing can still be reasons to filter at the tap.
Do I need a softener with a well?
On most wells, yes — hardness and iron clog filters quickly. Treating them first keeps the drinking system working.
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 — we drill stone counters with a diamond core bit, or use an existing sprayer or soap hole.
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.
Do I need a Oak Brook-registered contractor for kitchen water filtration?
Oak Brook does not require contractor registration; no village-specific requirements for residential alterations. We take care of that before work starts.
Does kitchen water filtration need a Oak Brook building permit, and who files it?
Permits go through Development Services (Building), phone (630) 368-5101. When your scope needs one, we prepare the application and schedule the inspections.
Does Oak Brook require a licensed plumber for kitchen water filtration?
Current Illinois plumbing license (055 and 058) or current City of Chicago license; other municipalities' business licenses not acceptable. Our plumbing connections are made by licensed plumbers.
Oak Brook water: how does it affect kitchen water filtration?
Oak Brook's water source: Purchased Lake Michigan water via DuPage Water Commission (Chicago Jardine plant); deep wells are emergency backup only; reported hardness is Lake Michigan water via DuPage Water Commission; regional hardness about 8 grains per gallon (137 mg/L as CaCO3). That decides which filter stages make sense.
Do I need a permit for kitchen water filtration in Oak Brook?
It depends on the scope. Oak Brook's rule in short: Village publishes a Residential Permit Requirement Listing; its Residential Alteration category requires contract/scope of work, architectural plans and plat of survey. We handle the permit when one is needed with Development Services (Building).
