Water Supply Fault Investigation

What the investigation covers

This service is designed to find the root cause quickly, minimise disruption, and leave you with a supply you can rely on.

• Checks on incoming mains supply and stop tap operation
• Investigation of low pressure, intermittent flow, or complete loss of water
• Tracing leaks, restrictions, failed valves, or defective fittings
• Isolation of affected sections to make repairs safely
• Repair or replacement of faulty components where appropriate
• Testing after work to confirm stable flow and pressure

When this service is most useful

Book a water supply fault investigation if you notice any of the following:

• Water stops and starts, especially at certain times of day
• Pressure suddenly drops across the property
• Only some outlets are affected, such as an upstairs bathroom
• You suspect a hidden leak, damp patch, or unexplained meter movement
• Recent plumbing work has led to poorer flow or noisy pipework

What to expect on the day

The visit starts with questions about what you have observed, then a structured set of checks to narrow down the fault. Where possible, the water supply is isolated in a controlled way to allow safe inspection and repair. You will be kept informed of findings, options, and next steps before any corrective work proceeds.

After the fault is resolved

Once repairs are complete, the system is tested to confirm performance and to make sure the issue is not recurring. If the investigation identifies a wider risk, such as ageing pipework or a pressure issue, you will get clear recommendations on practical next actions.
