What excavator is best for plumbing and sewer work?

Plumbing and sewer work requires precise trench excavation at specific depths and widths. For standard residential plumbing — water supply, hot water systems, irrigation — the 0.8T or 1T mini excavator is ideal. These machines dig precise trenches at the required depth without disturbing surrounding areas. For sewer connections — typically 1,000–2,000mm deep — the 1.7T excavator provides more digging depth (maximum 2,400mm) and greater digging force for harder soil conditions. For deep sewer mains or large-diameter pipes, the 3.5T excavator (maximum dig depth 3,800mm) is required. Plumbers across NSW regularly hire BuildHire's mini excavators for residential service trenching. Our machines can be fitted with narrow trenching buckets (200–300mm) for precise pipe trench excavation.
