Water Filtration & Reverse Osmosis in Lake in the Hills, IL

• Cloudy ice cubes that taste like the freezer

  Dissolved minerals cloud ice and carry flavor. Clear, neutral ice is one of the most immediately noticeable changes after an RO install.

• A chlorine or pool smell at the tap

  Municipal disinfection is doing its job, but the residual is easy to remove at the point of use with carbon and unpleasant to drink if you are sensitive to it.

• Coffee and tea that taste flat or metallic

  High dissolved solids flatten flavor and leave scale in the carafe. Anyone serious about coffee notices RO water immediately.

• You are buying bottled water

  If a case a week is a line item in your grocery budget, an under-sink RO unit pays for itself faster than almost any plumbing upgrade we install.

• White scale inside kettles and humidifiers

  Small appliances that boil or evaporate water concentrate minerals fast. RO water eliminates the descaling routine entirely.

• You want it for a specific reason

  Aquariums, espresso machines, infant formula, or a household member on a restricted diet. Each has a different ideal setup and we size accordingly.

1. 1. Figure out what you are actually solving

   Taste, odor, scale in appliances, or a specific contaminant concern. Chasing the wrong one means buying the wrong system, and there is no point filtering something that is not there.

2. 2. Test and read the report

   We test at the tap and, for municipal supply, walk you through the Village's published water quality report. Together those tell us whether carbon is enough or whether RO is the right answer.

3. 3. Pick point-of-use or whole-home

   RO is point-of-use — you do not want to run the whole house through a membrane. Carbon filtration can be whole-home and is the right tool for chlorine taste and odor throughout.

4. 4. Install cleanly

   RO unit mounts inside the sink base with a dedicated faucet at the deck, a drain saddle or air-gap fitting to the tailpiece, and a line run to the refrigerator ice maker if you want it.

5. 5. Flush and verify

   New membranes need flushing before the water is worth drinking. We flush, then test total dissolved solids at the new faucet and show you the before-and-after reading.

6. 6. Set the filter calendar

   Pre and post filters are typically annual; the membrane runs several years. We label the unit with dates so nobody is guessing in two years.

Point-of-use versus whole-home

An under-sink RO unit is a modest, contained install. A whole-home carbon system is larger, ties into the main, and costs meaningfully more.

Stage count on the RO unit

Three-stage units cover the basics. Four and five-stage units add finer sediment filtration and remineralization for taste. More stages means slightly more filter cost annually.

Refrigerator and ice maker line

Running RO water to the fridge is one of the most-appreciated add-ons and requires a line run through cabinetry, sometimes across a room.

Faucet choice

The dedicated RO faucet is visible on your counter. Basic chrome is included; a finish that matches your kitchen costs a bit more.

Existing plumbing under the sink

A crowded sink base with a disposal, a filtered pitcher line and a dishwasher branch takes longer to work in cleanly than an empty cabinet.

Softener interaction

RO works better and its membrane lasts longer on softened feed water. If you already have a softener, say so — it changes what we recommend.

Filter replacements are inexpensive and we will happily show you how to do them yourself. We would rather you keep the system working than sell you a service plan you do not need.
