If there’s leak in your system, there will be a few signs you need to look out for:

1. High water bills (if metered).
2. Musty smelling rooms.
3. Stained walls, ceilings, and floors.
4. Check you water meter has stopped when you shut off the water, if it continues then a leak is present.
5. Wet/damp areas will be obvious inside (beneath sink/basins/bath/water cisterns etc) and outside your home, stained walls.
