Mixing Valve Commissioning & Recirc Balancing in Orange County, CA
Mixed-hot systems drift without proper setup: valves out of tune, pumps too fast, and branches starved. We perform mixing valve commissioning & recirculation balancing so your building delivers safe, steady ~120°F water while minimizing wait time and energy use.
✓ Safer outlets: scald risk reduced
✓ Proof of work: readings and report
✓ Steady temps: dialed-in mixed setpoint
✓ Balanced loop: even hot water to all branches

What Is Mixing Valve Commissioning & Recirc Balancing?
A focused service to set the master mixing valve (or group valves) to a safe, stable delivery temperature and balance the recirculation loop so hot water arrives quickly and evenly.
We measure supply/return temps, adjust balancing valves and pump speed/controls, confirm check valves and bypass devices, and document results.
Why Choose White Glove Plumbing
Compliance & safety first: Distribution temps set for scald safety with anti-scald strategy at outlets.
Defensible documentation: Before/after temps, return line readings, pump settings, and valve positions.
Beyond a quick tweak: We flush strainers, verify checks/thermostatic bypasses, and correct pump control logic.
One accountable team: If hardware is failing, we can replace valves/pumps, add recirc controls, or service your heater same visit.
Immediate Actions (What to Do Now)
Note problem fixtures (too hot, goes cold, or long waits).
Share system details: tank/tankless/heat pump, pump model, mixing valve brand/size.
Tell us typical schedules (peak shower times, kitchen rush).
Clear access at the heater, mixing valve, and key risers.
Call our 24/7 dispatcher—we’ll test, set, and balance your loop.
Common Situations We Handle
Scalding bursts or lukewarm drift at showers/sinks
Hot then cold “yo-yo” caused by unbalanced returns
Dead-end branches or long waits at far fixtures
Overpumping that pulls cold into the mix valve
New installs needing first-time commissioning
After a heater upgrade (tankless/heat pump) changing loop behavior
Survey & Baseline
Identify valve/pump models, loop layout, and controls; record cold inlet, hot supply, mixed supply, and return temps at key points.
Clean & Verify Hardware
Clean strainers; confirm check valves, balance valves, and thermostatic bypasses are present and operable; verify sensor/aquastat placement.
Set the Mixing Valve
Adjust to target ~120°F distribution (or your spec); lock the setting; verify stability under low and peak flows.
Balance the Recirc
Throttle branch balancing valves, set pump speed or VFD, and tune aquastat/timer/demand controls to maintain return temps without overrun.
Stress Test & Fine-Tune
Run simultaneous fixtures; confirm no cold slugs, acceptable recovery, and quiet operation; re-check checks to stop crossover.
Document & Handover
Provide before/after logs, valve positions, pump settings, and a simple operator guide with recommended maintenance cadence.
What’s Included
System assessment with baseline temperature/flow notes
Strainer cleaning & hardware verification (checks/bypasses/balancers)
Mixing valve setpoint adjustment and lockout
Recirc balance (branch valves, pump speed/VFD, aquastat/timer)
Stress testing across representative fixtures/zones
Documentation packet (readings, settings, recommendations)
Costs & Timelines (What to Expect)
Scalding bursts or lukewarm drift at showers/sinks
Hot then cold “yo-yo” caused by unbalanced returns
Dead-end branches or long waits at far fixtures
Overpumping that pulls cold into the mix valve
New installs needing first-time commissioning
After a heater upgrade (tankless/heat pump) changing loop behavior
Insurance & Compliance Support
Inspector/PM-ready records: Distribution setpoint, return temps, and control settings.
Policy alignment: Scald-safety practices and local code temperature guidance; COIs for HOAs/PMs.
Future-proofing: Recommendations for point-of-use anti-scald where required.
Risks of Waiting (Why Act Now)
Scald risk at taps and showers
Bacterial growth risk from poorly controlled temperatures
Energy waste from overpumping and heat loss
Tenant/guest complaints and service calls
Methods, Materials & Quality Standards
Instrumentation: Calibrated thermometers and clamp probes on hot/mixed/return lines.
Practices: Stable ~120°F distribution unless otherwise specified; verify checks to prevent crossflow; balance for fast but efficient delivery.
Controls: Optimize pump timers/aquastats/demand; label final valve positions and settings.
Upgrades (as needed): Low-lead mixing valves, ECM pumps/VFD, thermostatic branch bypasses, insulation on hot/return lines.
Frequently Asked Questions
Will you change point-of-use valves?
We focus on the master mix and loop balance; we’ll recommend thermostatic faucets where needed.
What temp do you set?
Typically ~120°F distribution for safety/efficiency; we can tailor per facility policy.
Do I need new hardware?
Not always. Many issues are balance/control related. If parts are failing, we’ll quote replacements.
Can this help tankless systems?
Yes—proper recirc mode and balance prevent short-cycling and “cold sandwich” effects.
How long will it stay balanced?
With clean strainers and stable use patterns, 12+ months is common; we suggest annual checks.
