Leak detection in Iver: what if the meter chamber is dry but the garden stays wet?

Record the chamber without unsafe access

Photograph the chamber exterior, meter serial and complete display only where safely visible. Do not lift a heavy cover, reach into standing water or work beside traffic. Note that the chamber appeared dry at that time; do not translate the observation into “the supply is sound”.

If several meters are present, confirm the property identity through the supplier or records. A reading from the wrong meter can produce a convincing but useless no-use test. Shared supplies need coordinated demand information.

Map the wet ground independently

Photograph the garden patch from fixed landmarks and mark the first emergence, slope and changing edge. Add rainfall, irrigation and drain use. A low point can collect water from a defect some distance away, especially along a service trench.

Keep people and vehicles off sinking or softened areas. Do not probe, lift paving or excavate; gas, electricity, communications and drainage may share the route. Ground movement or fast flow needs prompt reporting and a safe exclusion area.

Use a defined meter interval

During a genuine no-use period, capture start and finish displays with exact times and list toilets, appliances, softeners and outside taps. Movement supports flow through the identified meter; it cannot locate the defect or distinguish intended automatic use without context.

The internal stop tap may help define whether flow sits before or after that valve, but only if it is familiar, accessible and easy to operate. Record uncontrolled branches and never use street controls as a home test.

Confirm the route before reinstatement

Provide plans, extension photographs and known entry points. Professional supply-pipe leak detection may combine route tracing, acoustic evidence and pressure or flow testing before an access point is chosen. Ask how the findings converge.

If a defect is exposed, photograph depth, material and nearby services, then update the route plan. Repeat the meter interval after repair. Saturated ground can remain wet, so post-repair flow evidence and slow surface recovery should be judged separately.

Ask the final report to distinguish the confirmed pipe route, the defect position and the point where water surfaced. Those three places may differ. Keeping them separate prevents future wet ground from being compared with an inaccurate straight line drawn between the meter and the old puddle.
