What's included

Real water improvements, not gimmicks.

Water filtration is one of those areas where homeowners get oversold every day. We test your water, identify the actual problem (hardness, iron, chlorine, sediment, taste), and recommend a system sized to the real chemistry. If you don't need a system, we'll tell you that too.

On testing, there are two things we do. We check hardness, iron, pH, and chlorine on-site while we're at the house. And we can collect a water sample and send it out through our supplier to a testing company for a full water-chemistry panel — the results come back to you along with recommendations. That panel is water chemistry; it is not a PFAS, fluoride, or lead test. If those are what you're after, the guides below lay out where to get them.

For town-water homes in Holliston, Framingham, Natick, and Ashland the most common needs are a basic carbon whole-house filter (for chlorine and taste) and a small softener (for moderate hardness). For well-water homes in Sherborn, Dover, Wayland, and Upton, we frequently install combined softener-and-iron-filter systems sized to the bore's chemistry, plus an under-sink RO unit for drinking water.

Every install includes proper sizing and a bypass valve so you can service the unit without shutting down the house. We also offer ongoing service plans so you don't have to think about it.

Common signs you need water treatment

Systems we install — whole house (point of entry)

Plumbed in at the main, so every tap in the house is treated — showers, laundry, hose bibs, and all.

Systems we install — under the kitchen sink (point of use)

One tap, treated thoroughly. This is where drinking and cooking water gets handled.

Those two lists are separate on purpose. Whole-house equipment treats the house; reverse osmosis treats the one tap it is plumbed to. We do not install whole-house reverse osmosis — an RO membrane produces water slowly and sends some to drain, which suits a drinking faucet rather than a whole home's flow demand. That is also why contaminants like PFAS, fluoride, and lead get addressed at the kitchen tap rather than at the main.

Our process

Test, specify, install.

Step 01

Water test

We check hardness, iron, pH, and chlorine on-site, and can send a sample out through our supplier for a full water-chemistry panel with recommendations.

Step 02

System spec

We size the right combination — whole-house softener and filters at the main, under-sink RO for drinking water.

Step 03

Plumbed-in install

Whole-house gear ties into your main with bypass and unions, drain and electrical set, unit programmed. RO goes in under the kitchen sink.

Step 04

Service plan

Optional service plan covers salt, filter changes, and annual sanitization. No surprises.

FAQ

Filtration FAQ.

Do I really need a water softener in Metrowest?
It depends on your water source. Town water (Holliston, Framingham, Natick) is generally moderate. Wells in Sherborn, Dover, and Wayland often test much harder, with iron or manganese as common problems. We test on-site and recommend honestly.
What's the difference between a softener and a whole-house filter?
A softener removes calcium and magnesium (the minerals that cause scale). A whole-house filter typically targets sediment, chlorine, taste, or specific contaminants like iron. Many Metrowest homes need both.
Where does an RO system get installed?
Under the kitchen sink with a dedicated drinking-water faucet on the countertop. We can also tie an RO system into a fridge water line for filtered ice and dispensed water.
How often does a softener need salt?
Most family-of-four softeners use 30–50 pounds per month, depending on hardness and usage. We size the unit so you're not refilling weekly.
Can you handle iron staining in well water?
Yes. Iron and manganese stains in laundry, fixtures, and toilets are common in Sherborn, Dover, and rural Wayland wells. We test, then specify a unit (often a softener with iron removal or a dedicated iron filter) sized to the actual water chemistry.
