Commercial Water Loss Surveys in Alhambra, CA
In a commercial building, unexplained water loss hides in scale: many fixtures, long pipe runs, irrigation, cooling and multiple tenants. A commercial water loss survey works systematically — reviewing consumption patterns, isolating the building into zones, testing each zone, and documenting findings so owners and facility managers can act on evidence rather than guesses.

Signs you may need this service
- Utility bills rising without an occupancy or process change
- Night-time meter flow that never reaches zero
- Wet areas, staining or pressure complaints in parts of the building
- A water audit target the property is failing to meet
- Disputes about which unit or zone is responsible for excess use
Individual symptoms do not always prove a leak — they justify a proper investigation, which is what this service provides.
What this service investigates
Whole-building distribution: incoming service, zone and riser isolation, fixture groups, irrigation and mechanical systems, prioritised by consumption data and access.
Who it is for
- Facility managers facing unexplained consumption increases
- HOAs and multi-unit owners with shared water systems
- Commercial owners preparing a water audit or efficiency programme
How the process works
1
Review available consumption and billing history to size the loss and spot patterns.
2
Divide the property into testable zones using existing valves and meters where available.
3
Isolate and test zones (including out-of-hours flow checks where agreed) to find which zone loses water.
4
Pinpoint within the problem zone, then deliver a written summary of findings and recommended next steps.
Equipment & methods
Meter and data-logger flow review where available, zone isolation and pressure testing, acoustic surveys of accessible pipework, and thermal/moisture checks of affected areas.
What affects the diagnosis
Access, valve condition and operating hours constrain what can be isolated and when; some testing is best done out of hours and is scheduled accordingly. A survey identifies water loss and its location — repairs, and any tenant billing questions, remain separate scopes.
What you receive
A documented summary: the size of the loss, the zone and location responsible, the evidence behind each conclusion, and prioritised recommendations.

Commercial Water Loss Surveys FAQs
What is an office building water audit versus this survey?
An audit reviews overall water use and efficiency. A water loss survey is narrower and more forensic: it hunts the unexplained loss itself, zone by zone, until the responsible section is identified. The two complement each other.
Will the survey disrupt tenants or operations?
Zone isolation is planned around the building's use, and disruptive steps are scheduled for agreed windows, including out of hours where needed. Most evidence-gathering (meter review, acoustic checks) is non-disruptive.
Can you tell which unit is using the water?
Where zone or sub-meter isolation is possible, loss can usually be attributed to a zone or unit group. The limits of the building's valving are explained before testing begins.
Do we get documentation for owners or insurers?
Yes. Findings are summarised in writing with the evidence for each conclusion — see also Structural Moisture Mapping where water has already damaged materials.

Pipeline Pressure Testing
Isolating a line and monitoring its pressure confirms whether it leaks, and which section — hot or cold, inside or outside — is responsible.
Acoustic Leak Detection
Electronic listening equipment picks up the sound of pressurised water escaping a pipe, so the leak can be pinpointed through floors and walls.
Think you have a hidden leak?
The sooner a leak is confirmed and located, the less water is wasted and the less damage spreads. Call now, or send a short request and describe what you are seeing.
