Cleaner, safer water for every Watertown home

CleanTap Water Solutions is a licensed Massachusetts company and certified BritaPRO installer serving homeowners throughout Watertown and ZIP 02472. From Watertown Square and East Watertown to the streets around Coolidge Square and the newer developments near Arsenal Yards, we begin every job the same way: with a free in-home water test so we know exactly what is at your tap before we recommend anything. With more than 60 years of combined experience and crews running from our Braintree and Mansfield bases, we understand Watertown’s dense mix of older two- and three-family houses and newer condos, and how their plumbing shapes the water you drink.

Watertown does not draw from local wells. The community buys wholesale water from the MWRA, sourced from the Quabbin and Wachusett Reservoirs, and the Watertown DPW Water Division distributes it through town. That treated surface water is relatively soft and disinfected with chloramine, so hardness is rarely the problem here. The bigger local concern is what the water flows through: older homes may still have lead service lines or lead solder, a recognized issue across the MWRA region. Point-of-use and whole-home filtration add a real layer of protection, giving your household cleaner drinking water while you evaluate and address older pipe.

We install and service the full range of home water systems: whole-home filtration to improve taste and reduce contaminants, under-sink reverse osmosis for clean drinking and cooking water, and treatment aimed at reducing concerns like lead where testing shows a need. Because Watertown’s MWRA water is already soft, many homes benefit more from targeted filtration than from softening, which is exactly why we test first. With $0-down financing available, protecting your family’s water is easier than most owners expect, and filtered water at the tap beats buying case after case of bottled water.

Everything starts with a free in-home water test. Our own experienced water specialists, with 60+ years of combined experience and certified BritaPRO installation, test what’s actually coming out of your taps, hand you a clear report, and only then recommend a system. You get upfront, fixed pricing, clean installation, and equipment matched to your water, not a one-size-fits-all package.

Whether you need a whole-home filter, a water softener for hard-water scale, a reverse-osmosis drinking-water system, or targeted PFAS and lead reduction, we handle it, with $0-down financing available. One trusted local number for water filtration, plumbing, and heating & cooling across your whole home.

Local knowledge

Watertown Water Quality: MWRA Supply, Older Pipes

Watertown does not draw from local wells. The town buys wholesale water from the MWRA, sourced from the Quabbin and Wachusett Reservoirs, and the Watertown DPW Water Division distributes it through town. This treated surface water is relatively soft and disinfected with chloramine, so the real water-quality question in Watertown is not where the water comes from but what it travels through on the way to your tap. Much of the housing is dense and older, with single-family homes alongside many two- and three-family houses near Watertown Square, East Watertown, and Coolidge Square, and older buildings may still have lead service lines or lead solder, a recognized issue across the MWRA region.

That is where CleanTap helps. We start with a free in-home water test at your Watertown property, then give you a clear, plain-English report of what we found and what it means for your household. If your home predates 1940, especially a triple-decker or multifamily, it is worth checking your service line and interior piping, and filtration can add real peace of mind. From there we recommend a right-sized system built for your home and water, from point-of-use protection to whole-home filtration. We always test before we recommend, so you get the right solution and nothing you do not need. Call (781) 630-5449.

Does your water need help?

Signs it’s time to test & treat your water

Your water can look fine and still carry hardness, contaminants, or things that damage your home. Here’s what to watch for.

Test your water soon

  • You’re on a private well and haven’t tested lately
  • Your water smells like chlorine, sulfur, or “off”
  • Orange, brown, or blue-green staining on fixtures
  • Your town or well may have PFAS or lead concerns
  • Cloudy or gritty water, or sediment in aerators
  • You buy bottled water because you don’t trust the tap

A filter or softener will help if

  • Spotty glasses, crusty faucets, and soap that won’t lather
  • Dry skin and hair, or stiff, dingy laundry
  • Water heaters and appliances wearing out early
  • Chlorine or metallic taste you’d rather not drink
  • You want cleaner drinking water without the bottles
  • You want peace of mind about PFAS, lead, and hardness

Water problems we solve

Common Watertown water problems, fixed at the source

If any of these sound familiar, a free water test will pinpoint the cause and the right fix, no guesswork.

Hard Water & Scale

Spotted glassware, crusty fixtures, dry skin, and appliances that wear out early? A softener fixes hard water at the source.

Bad Taste & Odor

Chlorine taste, a musty smell, or that rotten-egg odor? Filtration removes what makes your water unpleasant to drink.

PFAS & Contaminants

Worried about PFAS, lead, or what’s in your report? We match the right media or RO system to the contaminants in your water.

Rust & Staining

Orange or brown staining on fixtures and laundry usually means iron or manganese, common on wells, and very treatable.

Cloudy or Sediment Water

Cloudy, gritty, or sediment-filled water clogs aerators and appliances. Whole-home filtration clears it up.

Well Water Concerns

On a private well? We test for hardness, iron, manganese, bacteria risk, and more, then build the right treatment train.

“I called on a Sunday, my boiler was overfilling itself. Sean was patient and informative on the phone, then Luiz came out on a Sunday, fixed my leak, and got my heat up and running within the hour. Both were patient, helpful, and transparent about everything. I highly recommend their service!”

“They were fantastic. Very responsive and came out the next day. The plumber, Luiz, was very knowledgeable and efficient in getting the leak fixed. Did not feel upcharged, very straightforward. Highly recommend. Much better than other plumbers after interviewing multiple. They were the best.”

Questions

Watertown water filtration, answered

Is Watertown’s tap water safe to drink?

Watertown buys its water wholesale from the MWRA, sourced from the Quabbin and Wachusett Reservoirs, and it is treated, disinfected with chloramine, and monitored under state and federal rules. The bigger local concern is not the source but what the water flows through, since older homes may still have lead service lines or lead solder, a recognized issue across the MWRA region. The only way to know what is reaching your specific tap is to test it. CleanTap offers a free in-home water test and explains exactly what we find before recommending anything.

How does the free in-home water test work?

It is easy and comes with no cost or obligation. A CleanTap technician visits your Watertown home at a convenient time and tests the water right at your taps, so we see what is actually reaching your faucets rather than guessing. We then walk you through a plain-English report of the results and what they mean for your household. If filtration makes sense, we recommend a right-sized system with honest pricing and $0-down financing options. If your water looks good, we will tell you that too. Call (781) 630-5449 to book your visit.

I own an older home near Watertown Square. Should I worry about lead?

It is worth checking. Much of Watertown’s housing is old and dense, with many two- and three-family houses near Watertown Square, East Watertown, and Coolidge Square, and older buildings may still have lead service lines or lead solder, a recognized issue across the MWRA region. The water arriving from the MWRA is well treated, but lead can enter as it passes through aging pipe. CleanTap can help you evaluate your service line and interior piping and install point-of-use or whole-home filtration aimed at reducing lead. We start with a free in-home water test so any solution fits your home.

What water filtration systems do you install?

As a certified BritaPRO installer, CleanTap installs whole-home filtration to improve taste and reduce contaminants throughout the house, under-sink reverse osmosis for clean drinking and cooking water at the kitchen, and treatment aimed at reducing concerns like lead where testing shows a need. Because Watertown’s MWRA water is already soft, many homes benefit more from targeted filtration than from softening. Every recommendation follows a free in-home water test, and $0-down financing keeps it affordable. Call (781) 630-5449 to get started.

Is my tap water in Massachusetts safe to drink?

Most Massachusetts public water meets federal standards, but “meets standards” doesn’t mean pure, chlorine/chloramine, disinfection byproducts, hardness, and in some areas PFAS or lead from older service lines can still affect taste, safety, and your appliances. Private wells aren’t tested by any utility at all. The only way to know what’s in your water is to test it, which is exactly why we offer a free in-home water test and a clear report.

How does the free in-home water test work?

We come to your home, test your water on the spot for the things that matter, hardness, chlorine, pH, iron, TDS and more, and walk you through a clear report of what we find. There’s no cost, no obligation, and no pressure. If treatment makes sense we’ll recommend the right system for your water and budget; if it doesn’t, we’ll tell you that too. Call (781) 630-5449 to book.

What’s the difference between a water softener and a filter?

A softener removes the calcium and magnesium that make water “hard”, the cause of scale, spotting, and appliance wear. A filter removes things like chlorine, sediment, taste, odor, PFAS, or lead. Many homes benefit from both, which is why we test first and design a system, softener, whole-home filter, drinking-water RO, or a combination, around your actual water rather than a one-size-fits-all package.

Can you remove PFAS and lead from my water?

Yes. PFAS and lead are best addressed with the right technology, typically reverse osmosis and/or specialized filtration media at the point of use or whole-home. We test your water, review your town’s data, and match a system proven to reduce those contaminants. If you’re on an older service line or in an area with PFAS detections, this is worth doing.

Do you install reverse-osmosis drinking water systems?

Yes. Under-sink reverse osmosis is one of the most effective ways to get clean, great-tasting water for drinking and cooking, removing a wide range of dissolved contaminants. We can pair a kitchen RO system with a whole-home softener or filter so you get treated water at every tap and the highest-purity water where you drink it.

How much does a water filtration or softening system cost?

As a general guide in Massachusetts, under-sink RO systems typically run about $300–$800 installed, water softeners about $1,500–$3,500, whole-home carbon/sediment filtration about $1,500–$4,000, and advanced whole-home PFAS/RO systems roughly $4,000–$10,000. The right system depends on your water and home, so we test first and give you an upfront, fixed quote. $0-down financing is available.

Do you work with Brita?

Yes, CleanTap is a certified BritaPRO installer, and we install BritaPRO whole-home systems along with other leading filtration and softening equipment. Because we’re not tied to a single box, we recommend what actually fits your water and your home after we test it, not whatever we happen to stock.

Is filtered water cheaper than bottled water?

Almost always, yes. A household that buys bottled water often spends more over a few years than a good filtration system costs, and you skip the plastic, the lugging, and the storage. Whole-home and RO systems give you clean water at every tap for a fraction of the per-gallon cost of bottled, which is a big reason our customers make the switch.

I’m on a private well, can you help?

Definitely. Private wells commonly have hardness, iron, manganese, sulfur odor, sediment, and sometimes bacteria or other concerns, and no utility monitors them for you. We test your well water, explain what we find, and design a treatment train, softening, filtration, disinfection as needed, to make it clean, clear, and safe at every tap.

Will a filtration system need maintenance?

Most systems just need periodic filter or media changes and occasional checks, which we make easy. We’ll tell you the schedule for your specific system up front, and we’re a local call away when it’s time. Good maintenance keeps your water quality high and protects your investment.

Do you offer financing on water systems?

Yes. We offer flexible, $0-down financing on qualifying filtration and softening systems, so clean water fits your budget without a big up-front cost. We’ll go over the options with your quote after the free water test.

What areas do you serve?

Greater Boston, the South Shore, Metro-South, and Eastern Massachusetts, including Boston, Quincy, Braintree, Weymouth, Dedham, Norwood, Mansfield, Foxboro, Franklin, and Plymouth. Not sure if you’re in range? Call (781) 630-5449 and we’ll let you know and book your free water test.
