Groton Water Filtration Services

A Water Test Result Tells You What's There. A Filtration System Handles It.

If you’re like most homeowners on a private well in Groton, you already know your water has an issue before you call us. You’ve seen the rust-colored staining. You’ve smelled the sulfur. Or you had your well water tested and got a results sheet listing iron concentrations, bacteria counts, and dissolved solids, with no explanation of what any of it means for their household. 

That last situation is the one that surprises people. A test tells you what's in the water. It doesn't tell you which system addresses it, how it gets installed, or what you'll need to maintain it.

That's where our team comes in. At Fagundes Plumbing Heating AC, our Master-licensed plumbers assess your water source, review your test results with you in plain language, and recommend the filtration system that fits what your water contains. We install and service all major brands and system types, from whole-home carbon filtration to reverse osmosis (RO) drinking water systems to UV purification units for bacterial concerns. 

We've been doing this work across Massachusetts and New Hampshire since 2003, and the Groton area's well water comes up regularly enough in our work that we know exactly what we're looking at.

Water Filtration Systems We Install and Service

We work with all major brands and system configurations. What we install on your property depends on what your water contains and how your home is set up. 

The following are the systems we handle most often for Groton-area customers:

• Whole-home water filtration installation
• Reverse osmosis drinking water systems
• UV purification system installation
• Iron and manganese filtration
• Filter replacement and ongoing system maintenance
• Filtration system repairs

If you're not sure which of these applies to your situation, describe what you're seeing at the tap, and we'll steer you toward the right starting point.

What Groton Well Water Commonly Contains

Groton sits in Middlesex County, where a significant portion of residential properties draw from private wells rather than municipal supply. Well water quality in this part of Massachusetts varies by depth, geology, and how recently the well was tested.

Common water quality concerns in the Groton area include:

• Iron and manganese
• Hydrogen sulfide
• Coliform bacteria
• Sediment and turbidity
• Chlorine and disinfection byproducts

So what does this mean if your test came back with elevated readings? The answer depends on which contaminants are present and at what concentrations. Not every issue requires the same system, and installing the wrong one means spending money on equipment that doesn't address your actual water issues.

We Look at Your Water Before We Recommend a System

Let’s say a homeowner calls us after receiving a well water test showing 1.2 mg/L iron and a faint sulfur odor in the kitchen. The iron level is four times the EPA secondary standard. The sulfur is still coming through even after the water has sat in the glass. They've been told by a big-box store that a whole-home carbon filter will handle it.

That's not quite right.

Carbon filtration addresses chlorine, odors from organic compounds, and a range of other dissolved contaminants. But iron at that concentration requires an oxidizing filter or an iron-specific media filter designed to remove ferrous iron from the water before it reaches your pipes and fixtures. Installing a carbon filter in that situation would reduce some of the odor and miss the primary problem entirely.

Our process is built around avoiding that outcome. Before we recommend any system, our plumbers review your water test results, ask about what you're observing at the tap, assess your supply line and existing plumbing, and provide a clear explanation of the findings. Then we tell you what system fits your water and your home, with a written estimate before any work begins.

No pressure. No upsell. You understand the situation before you decide anything.

Frequently Asked Questions About Water Filtration

The following are the questions we hear most often from homeowners when they call us about water filtration. If yours isn't here, call us and ask it directly.

Do I Need a Water Test Before Installing a Filtration System?

Yes, and if you haven't had your well tested recently, that's the right place to start. A water test tells you exactly what your well contains and at what concentrations, which determines which filtration system will address your water. Installing equipment without test results means guessing, and the wrong system either underperforms or misses the primary issue entirely.

How Long Does a Whole-Home Water Filtration System Installation Take?

Most whole-home filtration installations are completed in a single day. The timeline depends on your existing plumbing configuration, where the system needs to be placed in the supply line, and whether any preparatory work is needed. We give you a clear picture of the scope before installation begins so you know what to expect on the day of the job.

Will a Whole-Home Filtration System Reduce My Water Pressure?

A properly sized system won't cause a noticeable pressure drop under normal household use. Pressure reduction happens when a system is undersized for the home's flow rate or when filter cartridges become clogged and need replacement. We size every system to your home's water demand and include the right pre-filtration to protect downstream components from loading up too quickly.

What Happens If My Well Water Tests Positive for Bacteria?

A positive coliform or E. coli result means your well water needs treatment before it's safe for drinking and cooking. The first step is shock chlorination of the well to eliminate the immediate contamination, followed by retesting to confirm the bacteria are gone. If contamination recurs or if your well is at ongoing risk due to its construction or location, a UV purification system provides continuous protection. Our plumbers assess the situation and walk you through the options.

Can You Service a System That Was Installed by Someone Else?

Yes. We service and repair water filtration systems from all major brands and configurations, regardless of who did the original installation. If you're not sure what system you have or when it was last serviced, we can inspect it, identify the equipment, check its condition, and tell you what it needs.

Your Water Affects Everything It Touches in Your Home

Your fixtures. Your appliances. Your water heater. Everything downstream of your supply line is affected by whatever your water contains. Iron that goes unfiltered keeps staining. Bacteria that go untreated stay in the water. A system that isn't maintained eventually stops doing its job.

Fagundes Plumbing Heating AC has been licensed to do this work in Massachusetts since 2003.
