Signs your lines need inspection
Brown or discoloured water coming from spray heads is often the first sign. Reduced spray distance on some heads but not others points to a partial blockage in the connecting line. Standing water near a line run (but not at a head) can indicate a cracked pipe or a fitting that has separated underground.
How the inspection works
The technician traces the line run from the distribution box to each spray head, checking pressure and flow at each junction. Blockages are cleared with a pressurised flush. If a section of pipe has collapsed or separated, it is excavated and replaced. The cleared system is tested head by head to confirm even distribution.
Keeping your lines clear
The best prevention is regular maintenance of the treatment tank itself. When the tank is not pumped on schedule, solids carry over into the effluent lines and accumulate. A filter at the tank outlet catches most of this carryover, but it needs cleaning at every pump-out. Trees planted near line runs are a common source of root intrusion and should be watched.
