Leak detection in Wallingford: is meter movement caused by an appliance?

List every automatic device

Record model, timer and normal cycle for connected equipment. Include toilets, irrigation and heating fill.

Do not disconnect appliances or safety systems to create a silent period. Use manufacturer instructions.

Photograph a defined interval

Identify the correct meter, capture start and finish times and record every use. Shared meters require coordination.

Movement shows flow through the meter, not whether an appliance used or leaked it.

Compare the event log

Mark appliance start, fill and drain times against the meter data. Note cycles with no unexplained flow and flow with no scheduled cycle.

This comparison can narrow the question before leak detection in Wallingford.

Verify after appliance or plumbing work

Repeat an equivalent cycle and quiet interval. Preserve the original settings and repair record.

If unexplained movement remains, investigate other fittings or the supply rather than resetting the same appliance repeatedly.

Keep settings stable during comparison

Photograph appliance timers and softener programming before the observation. A power cut, clock change or manual cycle can shift demand and make two nights appear inconsistent.

If a service engineer changes settings, record the new programme and reason. Future meter comparisons must use the revised schedule rather than treating changed automatic use as hidden leakage.

Choose an honest quiet period

Select a period when occupants can genuinely avoid water use and when automatic programmes are known. Record toilet flushes, drinking-water use and any heating top-up; do not rely on memory the next morning. The meter serial and display should be clear in both photographs.

If the property has a shared supply, one household cannot create a valid quiet interval alone. Confirm the arrangement before treating movement as leakage. Likewise, a boundary stop tap may not control every branch, especially an outside tap or older outbuilding.

The result should be framed narrowly: flow occurred or did not occur during a defined interval. It does not locate the source. Pair that fact with appliance timing and isolation boundaries so the next investigation is proportionate.

Questions to close the visit

Ask the investigator to record which automatic devices were active and which branches the chosen valve controlled. After any repair, compare both a scheduled appliance cycle and a genuine quiet interval. Together they show whether expected consumption remains distinct from the unexplained movement that prompted the visit.
