Testing supply, heating & waste systems separately
Leakage from a waste, soil pipe or fixture connection normally appears while water is being discharged. The relevant fixture is operated & accessible joints are observed, with dye, flow testing or CCTV used where those methods suit the suspected route.
Visible water damage can be remote from its source because moisture may track along pipework, joists, insulation or service openings. Moisture mapping & thermal observations are compared with the nearby supply, heating, fixture & waste routes before the relevant system is tested.
What happens during a leak investigation in Leyton
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.

Leyton leak detection FAQs
How would WOW investigate escape of water from kitchens or bathrooms in Leyton?
The relevant fixture is operated under controlled conditions while accessible traps, seals, wastes & joints are observed. Dye or flow testing may be used to confirm the route, & CCTV is considered only where an inaccessible drainage section needs internal inspection.
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 Leyton?
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.
Can thermal imaging confirm the exact leak position on its own?
No. Thermal imaging shows temperature differences that may help trace a route or identify an area for further checks, but an anomaly is not proof of a leak. It is interpreted alongside moisture readings, system isolation, pressure or flow testing, fixture operation & other suitable methods before targeted access is considered.
