Post-Filter Performance Testing in Orange County, CA
Installed filters should prove they’re working—at your flow rates, with your water. Our post-filter performance testing verifies treatment results at the tap with pre/post sampling, on-site readings, and targeted lab tests—then tunes flow/contact time and sets a clear media change-out cadence.

What Is Post-Filter Performance Testing?
A targeted check that measures influent vs. effluent at your filtration/treatment device to confirm it’s removing what it should—at real-world flows.
Field tests may include free/total/combined chlorine (chloramine), TDS, hardness, iron/manganese, pH, temperature, flow rate, and pressure drop. Optional lab testing confirms lead/copper, VOCs, PFAS, or bacteria (post-UV).
Why Choose White Glove Plumbing
Compliance & safety first: Correct sampling technique, fresh reagents, and chain-of-custody for lab panels.
Defensible documentation: Side-by-side pre/post numbers with locations, time, temp, and photos.
Beyond the numbers: We optimize flow/contact time, fix channeling/bypass, and right-size equipment.
One accountable team: We can replace media/cartridges, service RO/UV/softeners, and verify performance after changes.
Immediate Actions (What to Do Now)
List devices (carbon, catalytic carbon, RO, softener, UV) and install dates.
Pick sample points (influent, post-filter, point-of-use).
Pause cartridge changes right before testing if possible.
Note symptoms (odor, taste, spotting, low flow).
Call our 24/7 dispatcher—we’ll schedule on-site testing and any lab work.
Common Situations We Handle
Carbon “not working” complaints (odor/taste persists)
RO TDS not dropping or storage tank underperforming
Softener not softening after recent resin or brine issues
UV disinfection needing proof of efficacy downstream
Property managers needing documented verification after installs
Survey & Goal Set
Identify devices, media age, target contaminants, and sample locations (pre/post and point-of-use).
Test Plan & Setup
Calibrate meters, prep DPD reagents/titrants, install temporary pressure/flow gauges, and log baseline conditions.
Pre/Post Field Tests
Record free/total chlorine, combined chlorine (chloramine), TDS, hardness, iron/manganese (spot), pH, temperature, GPM, and ΔP across the device.
Targeted Lab Verification (As Needed)
Pull chain-of-custody samples for lead/copper, VOCs, PFAS, bacteria (post-UV) or others tied to your goals.
Analyze & Optimize
Compare removal vs. claims; adjust flow/contact time, correct bypass/channeling, set RO tank pressure, or service resin/media as indicated.
Document & Re-Test Plan
Deliver a side-by-side report, set change-out cadence, and schedule verification re-testing after any corrective work.
What’s Included
Pre/post sampling at selected devices/taps
Field readings (chlorine species, TDS, hardness, pH, temp, flow, pressure drop)
Optional lab panels (lead/copper, VOCs, PFAS, bacteria)
Performance analysis vs. targets and device specs
Optimization actions (settings, service recommendations)
Results packet/PDF with photos and maintenance schedule
Costs & Timelines (What to Expect)
Typical duration: 45–120 minutes on site; add time for lab panels.
Cost drivers: Number of devices/taps, lab scope (metals/PFAS/bacteria), access, and follow-up verification.
Clear estimate: Separate line items for testing, lab fees, service/parts, and re-tests—no surprises.
Insurance & Compliance Support
PM/HOA packets: Tap/device maps, pre/post tables, and lab certificates.
Inspector-friendly: Post-UV/bacteria proof, chlorine/chloramine performance, and RO TDS reduction documented.
Records kept: Baselines saved for annual comparisons and warranty claims.
Risks of Waiting (Why Act Now)
Media exhaustion and breakthrough without warning
Taste/odor complaints and tenant callbacks
Undersized carbon for chloramine leading to elastomer wear
Appliance damage from uncorrected hardness or iron
Methods, Materials & Quality Standards
DPD colorimetric tests (free/total chlorine), titration/photometry for hardness/iron as needed
Calibrated meters for TDS, pH, temperature; inline or handheld flow & pressure readings
Best practices: Pre/post comparisons at actual usage flows, confirm bed contact time, check for bypass/channeling, and verify RO tank pressure & membrane ratio
Documentation: Time/temperature/flow logged with photos and labeled fixtures
Frequently Asked Questions
How low should RO TDS be?
Depends on feed water and membrane; we look for % rejection and practical performance, not “zero.”
Will a softener make TDS drop?
No—softeners exchange hardness; TDS stays similar. We verify grains reduction, not TDS.
Can carbon handle chloramine?
Yes—catalytic carbon with proper bed contact time. We size, test, and document it.
How often should I re-test?
At media change-outs, after taste/odor complaints, or annually for PMs/HOAs.
Is this a potability test?
Not by itself. We can add bacteria/metals/PFAS labs when needed.
