Leak detection in Thatcham: running water is heard beneath a concrete floor

Describe the sound under controlled everyday conditions

Choose a quiet time and note which taps, appliances, toilets and heating systems are idle. Record the room, time and whether the sound is continuous, pulsing or linked to a boiler or pump. A short audio clip can preserve character, although phone recordings cannot measure leak intensity or depth.

Compare several safe listening positions without pressing tools into the floor. Mark them on a sketch. Do not drill, chase or lift finishes to follow noise, because services may be embedded and concrete can transmit sound far from its source.

Look for a second line of evidence

Check for meter movement under supplier guidance, unexplained consumption, falling heating pressure, a warmer or cooler patch, damp edges and changes to adjacent skirting. Each clue applies to a different system possibility. A sound with no moisture still warrants investigation when it is persistent and new.

Note recent plumbing, heating or renovation work and whether the sound changes when normal systems cycle. Do not operate communal or unlabelled valves as an experiment. Safe isolation tests should have a defined boundary and be carried out by someone who understands the installation.

Let evidence choose the access point

Non-destructive leak detection in Thatcham may use acoustic information alongside pressure, thermal or moisture evidence. No method should be treated as a magic pointer; the investigator interprets several results and states the limits before proposing access.

Keep the area clear if flooring lifts, water emerges or electricity may be affected. Provide the sound log, plan and system history. Opening a concrete floor is disruptive, so the sensible objective is not to chase the loudest noise but to build enough consistent evidence for a targeted decision.

Ask the investigator to explain which observations support the proposed access area and which uncertainties remain. Keep a copy of readings and marked plans. If later repair work reveals a different route, that record still shows why the earlier decision was reasonable and prevents unsupported certainty in the handover. Photograph the opened area before it is closed. Record the actual pipe route found.
