The central city is the area inside the Four Avenues and mixes the commercial core with residential pockets such as Inner City East, Inner City West, the Avon Loop and Victoria. It was heavily damaged in the September 2010 earthquake and devastated in February 2011, and most of the city's high-rise buildings and many heritage buildings were demolished afterwards. The 2012 recovery plan set aside the East Frame for new residential development, and the council aims for 30,000 people living within the Four Avenues. We start every leak detection job in Christchurch Central with a simple meter and pressure test, then use listening gear and a thermal camera to pinpoint the leak so only a small area needs opening.
Finding leaks in rebuilt central city apartments
Most people living inside the Four Avenues are in buildings that went up after the 2011 demolitions, and leak detection here is mostly about multi-storey plumbing. Water from a failed fitting in one apartment can travel along a floor slab or down a service duct and appear two floors lower, or in a corridor, so the stain rarely marks the source. We start by isolating the affected unit's hot and cold supply and checking whether its meter or sub-meter moves, then work up and across to neighbouring units and the shared risers.
Modern buildings help in one way: the plumbing is newer and usually documented, so the as-built plans tell us where pipes run before we listen. Thermal imaging is useful on hot water lines in concrete, and pressure testing a single line confirms which one has failed without opening walls on a guess. Access is the slow part. Body corporates, building managers and other owners often need notice, and commercial tenants on lower floors may have trading hours to work around.
Where a home in a pocket such as the Avon Loop sits on its own section, the supply pipe from the boundary is the owner's to maintain and the familiar checks under the floor and along the buried line apply. With about 23 freezing nights a year, frost splits are less common here than in the outer suburbs, but pipes in unheated carparks and service areas can still be exposed.
Local tip: If water appears in your central city apartment, photograph it and tell the building manager before calling us, so access to the units above can be arranged for the same visit.
Leak Detection in Christchurch Central: Local Factors
On land that moved in 2010 and 2011, supply pipes can be stretched or cracked, and repaired sections can leak at the joins. We test the line and find the weak spot.

Leak Detection Christchurch Central FAQs
Will you need access to other apartments to find the leak in mine?
Often, yes. A leak showing in your unit can start in the one above or in a shared riser, so we ask the body corporate or building manager to arrange access to the units and service spaces we need to test.
Who is responsible for a leak at my Christchurch Central property?
In Christchurch City the council looks after the pipe up to your boundary and the toby box, and you look after the supply pipe from the boundary into the house. Selwyn and Waimakariri set their own rules, so we check them for your address.
Can you find leaks under concrete slabs?
Yes. We use pressure testing and listening gear to locate leaks under slabs.
