Compare water use with activity in the home
Look at actual meter readings as well as bills. Increased occupancy, laundry loads or a faulty toilet can change consumption. A higher bill alone does not establish that an underground pipe is leaking.
Keep a short record
Write down what changed and when, without entering any resident personal information.
- Dates and photographs of visible damp
- Meter readings and the times they were taken
- Pressure changes on the affected heating system
- Rooms or services affected
- Recent plumbing work or attempted repairs
Take the pattern to the first call
Tell ADI whether the problem is continuous, follows rainfall or appears when a particular bathroom is used. The team can then discuss the appropriate investigation and any preparation needed.
