Irrigation.
This particular job a wet patch had appeared in the garden some 8m away from the irrigation box.
After digging in the area of the wet patch, nothing was obvious. The water was seeping in from one side of the excavation about 100mm below the surface. After removing the irrigation lines at the isolation point, it was obvious that the centre line was letting water through, a quick replacement of the valve and check in the excavation, it was clear that the problem was solved.
Some problems are not always obvious but thorough investigation leads to a solution. Meeting your plumbing needs.
