Testing supply, heating & waste systems separately
Commercial water or mechanical faults are investigated around the affected service. Accessible pumps, valves, joints & distribution pipework are inspected before suitable isolation, pressure, flow, moisture or thermal checks are selected.
A falling reading on a sealed heating system may be caused by an accessible component, a discharge point or concealed heating pipework. The visible parts of the system are checked before isolation, pressure testing or specialist location methods are considered.

What happens during a leak investigation in Harlow
Confirm the symptom
We establish where water has been noticed or whether the boiler or sealed heating circuit is losing pressure, when the problem occurs & which fixtures or systems are operating at the time.
Map the affected area
Accessible components are inspected & moisture meter readings are used to map the spread. A thermal camera may identify temperature patterns, but thermal imaging is not treated as proof on its own.
Separate possible sources
Cold water supplies, hot water services, sealed heating circuits, fixtures, wastes, drainage & condensate routes are considered separately. We assess heating pressure loss separately from changes in mains pressure or flow, & check hot water pipework for leakage or performance faults.
Test the relevant system
Depending on the evidence, checks may include meter monitoring, staged isolation, pressure testing of suitable supply pipework or a sealed heating circuit, controlled fixture use, dye testing or CCTV inspection. Drainage checks focus on discharge, flow & accessible connections.
Narrow the source area
Acoustic listening equipment, tracer gas & borescope inspection may be introduced where the pipework & conditions suit those methods. No single instrument reading is relied upon without supporting evidence.
Explain the findings
The results are compared & explained, including any limitations. Targeted access is recommended only where the evidence supports a particular route or source area, & repair or access work is quoted separately.
Relevant services
From locating the cause to planning the repair
Specialist leak detectionFor commercial water loss, WOW begins with a visual inspection, symptom history, moisture mapping & thermal imaging. Each possible water source is then checked separately through isolation, pressure or controlled use. Acoustic equipment, tracer gas, dye, CCTV or a borescope is selected according to the system, & results are compared before access or repair is recommended.Drainage investigationDye, flow or CCTV checks may be selected when leakage or odour occurs during discharge rather than under water pressure.Heating & hot waterHeating circuits may be isolated or monitored when pressure drops without an obvious discharge point.

Questions answered
Harlow leak detection FAQs
How would WOW investigate commercial water loss in Harlow?
Accessible pumps, valves, joints & distribution pipework are inspected first. Where the system can be safely isolated, suitable pressure, flow, moisture or thermal checks are selected for that service before repair or targeted access is recommended.
How long does a leak detection survey usually take?
Some leaks can be located within a few hours; others may take several days of investigation, depending on the system, how often the leak occurs & the time needed to isolate & test sections. We explain the approach & agree the charging arrangement before proceeding. View Terms & Conditions
How much does leak detection cost in Harlow?
Hourly leak detection is £100/hr + VAT from 8am to 5pm, £125/hr + VAT from 5pm to 9pm & £150/hr + VAT after 9pm. Alternatively, a complete leak detection survey is £450 + VAT from 8am to 5pm, £550 + VAT from 5pm to 9pm & £650 + VAT after 9pm. Pressure testing, tracer gas analysis, moisture meter testing, thermal imaging, acoustic detection, dye testing & borescope inspection are included in the fixed price leak detection survey where appropriate. CCTV surveys of drainage pipes, power flushing & moling are charged separately. The price is agreed before work begins. Repair or access work outside the survey is quoted separately.
What happens if WOW cannot find the leak?
WOW's No Find, No Fee policy applies where a genuine active leak is within the agreed fixed price or hourly investigation but its source cannot be identified during that investigation. Terms apply. Rising damp, condensation, building defects & other non leak causes are excluded because the specialist testing has still been completed. Where evidence is limited or the fault is intermittent, the findings & the most appropriate next step will be explained without claiming an unsupported location.
Will floors, walls or ceilings need to be opened?
Not automatically. The objective is to narrow the source before opening a surface. If the combined test results support a particular pipe route, fitting or source area, targeted access may be recommended for confirmation & repair. Excavation, access work, repairs, materials, waste removal & reinstatement are not included in the survey price & are quoted separately before work proceeds.
What happens before targeted access is recommended?
WOW compares the visible damage with the route of nearby supply, heating, hot water, waste & drainage services. The relevant system is then isolated, monitored or operated using suitable diagnostic equipment. Targeted access is recommended only when the combined evidence supports a particular pipe route, connection or source area; opening up may still be required for final confirmation & repair.
