How faults are narrowed down

Start with the affected system

Unexpected meter movement can support a supply leak investigation, but outlets, appliances, storage & accessible controls must be considered before the reading is attributed to concealed pipework.

The reported timing & system behaviour are considered together so that a suspected cause is not presented as confirmed without supporting evidence.

Known outlets & water using appliances are checked or isolated before meter behaviour is assessed. Supported supply loss can then be narrowed using suitable isolation, pressure, acoustic or tracer gas methods.

Specialist leak detection process

What happens during a leak investigation in Bexley

1

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.

2

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.

3

Separate possible sources

Cold water supplies, hot water services, sealed heating circuits, fixtures, wastes, drainage & condensate routes are considered separately. Pressure loss refers only to the sealed heating circuit; hot water services are checked for leakage or performance faults.

4

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. Ordinary drainage is tested during discharge, not as a pressurised service.

5

Narrow the source area

Acoustic listening equipment, tracer gas & boroscope inspection may be introduced where the pipework & conditions suit those methods. No single instrument reading is relied upon without supporting evidence.

6

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.

Questions answered

Bexley leak detection FAQs

How would WOW investigate unexpected meter movement when outlets are closed in Bexley?

All known outlets & water using appliances are first checked or isolated before the meter is monitored. If continuing water use is supported, accessible isolation points, pressure testing, acoustic listening or tracer gas may be used to narrow the affected supply route.

How long does a leak detection survey usually take?

Please allow approximately 2–3 hours on site for a complete leak detection survey, including up to 2 hours of pressure testing where appropriate. The time varies with the number of systems requiring checks, available isolation points & whether the fault occurs during the visit. Very slow or intermittent losses may require monitoring, staged isolation or a further agreed test before a reliable location can be confirmed.

How much does leak detection cost in Bexley?

A complete leak detection survey is £500 + VAT from 8am–5pm, £600 + VAT from 5pm–9pm & £700 + VAT after 9pm. Tracer gas is included where required. 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 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.

How does WOW decide which leak detection test to use?

The reported symptom is first matched to the system that could produce it. Suitable supply pipework & sealed heating circuits may require isolation or pressure testing; only a sealed heating circuit is described as losing system pressure. Hot water services are checked for leakage or performance faults, while wastes & drainage are operated & observed during discharge. Thermal imaging, moisture mapping, acoustic listening, tracer gas, dye testing, CCTV or a boroscope are then selected only where they can provide relevant evidence.
