What Happens During a Free Water Test?
If you’ve never scheduled a free water test before, it’s normal to wonder what’s involved. Is it quick? Will someone try to sell me something? What exactly do they test for?
This article walks you through the process step by step so you know what to expect—from the moment your technician arrives to the moment you receive your results.
- What Happens During the Appointment
Your water test appointment typically takes 30 to 60 minutes, depending on the size of your home and any questions you may have. We aim to keep the process smooth, informative, and pressure-free.
When your technician arrives, they’ll:
- Briefly discuss any concerns you’ve noticed (taste, odor, staining, etc.)
- Collect a water sample from a kitchen faucet or other fixture
- Perform on-site testing for key water quality indicators
- Conduct a visual assessment of your plumbing system, including pipe material, pressure tanks, existing filters or softeners, and available space for treatment equipment
This plumbing evaluation helps us identify any existing issues and ensures that any system we recommend is designed to work seamlessly with your home.
⏱️ Most tests take between 30 and 60 minutes and include time to review your results and answer any questions.
- What We Test For On-Site
During a free water test, we check for several common water quality issues that affect your home’s plumbing, water-using appliances, and daily comfort. These on-site tests provide fast, actionable insights using professional-grade tools.
| Parameter | What It Tells Us |
| Hardness | Measures calcium and magnesium levels that cause scale and soap issues |
| pH | Indicates if the water is acidic or alkaline, which can lead to pipe corrosion |
| Iron | Often responsible for rust-colored stains in sinks, tubs, and laundry |
| Total Dissolved Solids (TDS) | Shows overall mineral and contaminant concentration |
| Chlorine/Chloramine (if needed) | Tested when municipal water is used or customers report dry skin, hair issues, or strong taste/smell |
| Hydrogen Sulfide (rotten egg smell) (if needed) | Tested when there’s odor present, often in private well systems |
Tests are completed using handheld meters and reagents, giving you immediate results for most parameters.
- When Lab Testing Is Recommended
In some situations, we recommend sending water samples to a certified lab for a more detailed analysis. This is especially helpful when:
- You’re buying or selling a home and need certified documentation
- You use a private well and haven’t tested it in the past year
- There are potential health concerns (e.g., lead, bacteria, nitrates, PFAS)
- You’re planning to install a reverse osmosis or whole-home filtration system and need a precise water profile
Lab testing can identify contaminants that aren’t detectable through on-site methods and provides a comprehensive report you can rely on for both health and system design decisions.
💵 There is a fee for lab testing, which varies based on what’s being tested. We provide all pricing upfront, with no surprise charges—so you can make a fully informed choice.
- Reviewing the Results and Next Steps
After testing, your technician will walk you through the results in plain language. You’ll learn:
- Whether your water meets recommended quality standards
- What’s causing any staining, odor, or performance issues
- Which treatment options—if any—are appropriate for your needs
There’s no pressure to buy. If treatment makes sense, we’ll provide clear recommendations and system design options tailored to your home’s layout, plumbing, and budget.
- Real-World Example: Fast Answers, Clear Options
A family in Pottstown contacted us about a sulfur smell in their water. Our technician arrived the next day and confirmed hydrogen sulfide was present. We discussed options, and they decided to install a simple carbon pre-filter and aeration system. The smell disappeared immediately—and the kids stopped complaining at shower time.
Final Thoughts: It’s Free, It’s Fast, and It’s Worth It
You don’t have to guess what’s in your water—or wait until it causes damage. A free water test gives you real answers, often on the spot, with professional insight and a straightforward path forward.
Whether you’re dealing with taste, smell, staining, or just want peace of mind, we’re here to help.
