FAQ

Common Questions, Answered Honestly

Is the water test really free?

Yes. 100% free, in your home, with results in minutes. If your water's fine, we'll tell you and leave. It usually isn't — Rhode Island has moderately hard water statewide plus active PFAS concerns.

What's the deal with PFAS in Rhode Island?

RI set a limit of 20 parts per trillion for six PFAS chemicals in 2024, and some towns have had "do not drink" orders. You can't taste or see PFAS — a test is the only way to know. We carry filtration rated to reduce it.

Do I need a softener AND reverse osmosis?

They do different jobs. A softener fixes the water for your whole house and appliances. RO fixes the water you actually drink and cook with. Most homes want both — one protects the house, one protects the family.

How often do filters get replaced?

Typically every 6–12 months depending on the system. With our membership, we track it and handle it for you, so your system never stops protecting you.

Do you offer financing?

Yes — every system can be financed with approved credit. We'll walk you through the payment options during your free water test.

Do you serve private wells?

Yes — well owners are a big part of who we help. Nobody tests your well water but you, and that's exactly where problems hide.
