Common Questions
What's the difference between whole-home filtration and reverse osmosis?
Whole-home filtration treats all the water coming into your house: showers, laundry, every faucet. Reverse osmosis is a smaller system, usually under the kitchen sink, that gives you extra-clean water for drinking and cooking. Our complete system includes both.
How do I know if I need a water softener?
White spots on dishes and glass, crusty buildup on faucets and showerheads, dry skin, and a water heater that doesn't last are all signs of hard water. A softener takes care of all of it.
Do you work on both well water and city water?
Yes. City water systems are $2,950 installed. Well water usually needs extra treatment for iron, sulfur and sediment, so those start at $3,750. We check your water first so you get the right setup.
What does carbon filtration do?
Carbon pulls out the chlorine and chloramine the city adds to the water, along with the chemical taste and smell that come with them.
Is the price you give me the final price?
Yes. The price you hear is the price you pay. No upsells and no surprise fees on install day.
How long does installation take?
Most homes are done in one day.
How do I pick the right system?
You don't have to figure it out yourself. Tell us whether you're on city or well water and what you're noticing, and we'll recommend what fits your home and budget.
