1. Under-sink connections
Look for moisture, corrosion or staining around flexible hoses and valves.
2. Water heater condition
Rust, noise or water around the base are worth having inspected.
3. Drain speed
Slow drains can indicate a developing blockage.
4. Water meter readings
A meter moving with all outlets closed may point to a hidden leak.
5. Ceiling and wall staining
Discolouration below wet areas should be investigated early.
