Professional Water Testing in Orange County
Know your water before choosing a treatment system.
We use professional Hach and Hanna Instruments test equipment to measure key water-quality parameters on site. Hardness and total chlorine readings help us design, size, and verify custom water softening and filtration systems—not recommend equipment based on assumptions.
Measured. Documented.
Engineered.
Water Hardness
Calcium and magnesium hardness · grains per gallon (gpg)
Total Chlorine
Digital colorimetric measurement · mg/L (ppm)
Test first. Specify second. Verify after installation. A useful water assessment connects measurable conditions to a treatment decision—not simply to a sales pitch.
The instruments behind our recommendations
We use established testing methods to establish baseline water conditions and check treatment performance. The instrument is only one part of the process: sample location, reagents, timing, and interpretation matter too.
Hach hardness titration
We measure total water hardness using Hach drop-count titration. The chemical endpoint indicates hardness associated primarily with calcium and magnesium. We report the result in grains per gallon (gpg), which directly informs softener selection, capacity settings, and regeneration programming.
Hanna HI711 Total Chlorine Checker HC
The Hanna Instruments HI711 is a handheld colorimeter used to measure total chlorine in water. The reading provides a documented disinfectant baseline and helps evaluate chlorine reduction across a properly designed catalytic carbon stage.
Technical distinction: The HI711 measures total chlorine, not free chlorine alone. A separate free-chlorine measurement is required to estimate combined chlorine by difference; a total-chlorine reading by itself does not identify chloramine concentration.
Two measurements. Important design decisions.
Water that looks clear can still be very hard or carry a disinfectant residual. Measured results help us choose treatment technologies for the problem actually present.
Correct softener sizing
Hardness and estimated water consumption inform usable exchange capacity, salt settings, regeneration frequency, and valve programming. A guess can lead to inefficient settings or inconsistent results.
Filtration selection
Total chlorine readings help establish baseline disinfectant levels. Source-water chemistry, peak flow, contact time, and treatment goals influence selection of catalytic carbon and other equipment.
Performance verification
Testing untreated and treated sample points lets us compare conditions after startup. Hardness and total chlorine checks can help confirm that the installed system is performing as intended.
From the first water sample to the final system settings
A water assessment is most useful when we also understand where the sample comes from and how the home’s plumbing system is arranged.
Inspect & sample
We review the incoming-water arrangement and select an appropriate sample point, typically on the untreated supply when accessible. Existing filters, softeners, bypasses, and irrigation connections can affect where we test.
Measure & interpret
We test relevant parameters using the selected field methods, document results and units, and explain what those results do—and do not—tell us about your water.
Design & verify
We match equipment to water chemistry, peak flow, plumbing layout, and treatment goals. After installation, repeat tests at an appropriate treated-water point can verify key treatment outcomes.
We turn test results into a treatment specification.
The water report is the beginning—not the end—of system design. We combine field measurements with operating flow, available pressure, service access, drain provisions, and household or commercial demand.
Water quality & treatment plan
We document actual readings during the assessment and use them to guide the proposed system and commissioning checks.
Results are measured at the property and documented with the appropriate units.
Field water testing versus laboratory analysis
Our routine on-site assessment is designed to answer specific water-treatment questions. It is not a substitute for comprehensive laboratory testing when drinking-water safety, regulatory compliance, or uncommon contaminants are a concern.
What field measurements can tell us
Hardness establishes a useful basis for water-softener sizing and programming. Total chlorine helps us assess disinfectant residual and compare levels before and after appropriate treatment. Additional parameters can be evaluated when the project requires different methods or testing arrangements.
When a certified laboratory is necessary
Testing for lead, arsenic, PFAS, many pesticides, microbial contamination, and other specific health-related or regulated constituents generally requires appropriate laboratory methods. A basic hardness/chlorine assessment cannot establish whether water is safe to drink.
Orange County context: Water conditions can differ by utility, source blend, neighborhood, and time. We test the actual supply at the property rather than assigning one fixed hardness or chlorine value to an entire city.
Water testing questions, answered
Practical answers about Orange County water testing, hardness, chlorine, equipment, and water-treatment design.
What water tests does Pro Filtration perform?
Our core on-site assessment includes total hardness testing with Hach drop-count titration and total chlorine testing with a Hanna Instruments HI711 Checker HC. The scope can vary with the water source and project needs.
How do you test water hardness?
We use a Hach hardness titration method to measure total hardness, principally calcium and magnesium. Results are commonly expressed in grains per gallon (gpg), helping determine softener sizing and regeneration settings.
What does the Hanna HI711 measure?
The Hanna HI711 Checker HC measures total chlorine using a colorimetric method. Total chlorine includes free and combined chlorine. A separate appropriate test is needed to measure free chlorine independently.
Can a total chlorine test tell whether my water contains chloramine?
Not by itself. Total chlorine includes free and combined chlorine, but a total-chlorine reading alone does not quantify chloramines. Additional testing and information from the water supplier may be needed.
Why test water before installing a softener?
Actual hardness helps establish appropriate softener capacity and control-valve programming. Plumbing conditions and water consumption also matter. Testing reduces reliance on broad citywide averages.
Can you test water after installing filtration?
Yes. Comparing appropriate untreated and treated sample points can help verify hardness reduction and selected disinfectant-removal performance after system startup, using the corresponding test method.
Is an on-site water test the same as a lab-certified drinking-water test?
No. Field tests answer selected treatment questions. Health-related contaminants such as lead, arsenic, PFAS, and microorganisms require suitable analytical methods, often through an accredited laboratory.
Does water hardness vary across Orange County?
Yes. Water sources and distribution systems can vary among communities and over time. Testing a property’s actual incoming water gives a more useful design baseline than relying on a single number for a city.
