Water supply work
Copper pipe repairs
Copper is the backbone of Sydney's older water plumbing, and it fails in recognisable ways: pinholes where decades of internal erosion thinned the wall, splits where water hammer found a weak point, and joints let down by old soldering. A proper repair cuts back to sound metal and rebuilds the section, it never bandages decay.
Scope
What this covers
Cutting out split or pinholed lengths back to clean material
New joints made by silver brazing or press-fit connection
Replacing work-hardened bends and repeatedly repaired segments
Re-clipping pipework so movement stops stressing the repair
Timing
When it's needed
A green-stained wall, drummy plaster along a pipe run, repeated pinholes in one line, or a bang inside a wall followed by a hiss. Several failures along the same run usually argue for resectioning instead of a third spot fix.
Never step into standing water in a room where the power is still on, and stay from under any ceiling sagging with the weight of water. If the supply cannot be isolated and water is approaching the switchboard, keep everyone clear and treat the situation as an electrical emergency first and a plumbing problem second.

What shapes the scope
Length of pipe that must come out to reach sound material
Access: in-wall and in-slab runs versus exposed pipework
Whether hammer arrestors or pressure limiting should be added
Condition of the surrounding lines most likely to fail next
Repairing water supply pipework in NSW is licensed plumbing work regulated through NSW Fair Trading under the Home Building Act. Whoever repairs a burst must hold a current plumbing licence, ask to see it, and certifiable work should come with a compliance certificate on completion.
