Leak Detection in Māngere Bridge
Intermittent meter movement with no clear pattern needs careful interpretation. You might see the indicator turn, stop, then move again when nobody appears to be using water.

Job done and tidied
We finish the work and leave the site clean.
That needs checking, but the movement alone cannot tell us where water is going. Stately covers Māngere Bridge, and we approach this by comparing meter readings with actual household use, then narrowing down the supply in stages. Your observations help us choose useful checks rather than chase a single brief movement.
Record what happens between movements
Start with a short record of when the meter moves, how long each burst lasts and whether the numbered reading changes. Take a clear photo before and after an observation period. Note anything running indoors or outdoors, including appliances that might draw water partway through a cycle.
Ask everyone at home to tell you when they use water during that period. Listen for a toilet briefly refilling or a tap dripping, but keep covers and fittings intact. A burst that follows a known use gives us a different starting point from movement while everything has been deliberately left idle.
Check the meter against household use
Onsite, we first review those observations and establish which supply the meter serves. We compare its behaviour during a controlled quiet period with its response to a known draw of water. This helps distinguish recorded consumption from an indicator movement that needs more context.
We then check accessible fixtures and water-using appliances for intermittent operation. A toilet valve could admit water occasionally, for example, even if it is quiet when we arrive. If the meter remains still throughout the visit, we explain that limitation and agree on a repeat observation period rather than declare the pipework sound.

Narrow the search through isolation
Where suitable valves are available, we isolate parts of the plumbing and watch how the meter responds. The sequence matters: changing several things together can hide which branch affected the result. We also check whether an isolation valve has actually stopped flow before relying on that test.
Please keep the meter and accessible shutoffs clear, and tell us about any areas we cannot enter. We explain interruptions before turning water off. If a valve will not operate safely, or pipework has no useful isolation points, further access or additional testing may be needed before we can narrow the search.
Explain what the findings support
If movement stops when one branch is isolated and returns when it is restored, that points the investigation towards that branch. It still needs checking at the fixture or pipe level. Depending on access and the suspected location, pressure checks or listening tests may help refine where to investigate next.
An intermittent fault can stay quiet during testing, so we separate confirmed observations from likely explanations. Before any opening is proposed, we explain the suspected area, the reason for accessing it and what remains uncertain. Finding the cause may require lifting a cover, opening a surface or exposing pipework.
Agree on repairs and follow-up checks
Repair decisions follow the evidence. A confirmed fixture fault calls for work at that fixture; a confirmed leak on the supply between the meter and house may call for water main repairs. We explain the proposed scope, required access and any remaining uncertainty before agreeing on the work.
After repairs, we repeat relevant checks and compare the meter behaviour with the earlier observations. Because the original movement was intermittent, a quiet few minutes may not be enough. Your handover should identify what was checked, what was repaired, any access needing reinstatement and how long to monitor for further unexplained movement.
Leak detection: questions from Māngere Bridge
Can I run a longer meter check myself?
Watercare recommends using no water for four hours or more, recording readings before and after, and leaving the meter tap on. Choose a period when everyone can avoid water use, including automatic appliances.
What if the movement stops before you arrive?
Keep your photos and notes. A quiet meter gives us a snapshot, not an explanation for earlier movement. We can check accessible fixtures and plan further monitoring.
Should I book if I have only seen one burst?
First note the reading and check whether anyone used water. If unexplained bursts recur or the recorded volume increases during a quiet period, contact Stately with those observations.

I had the team come out to install a gas hot water system for me recently and it was an absolute pleasure to have these guys come out and do some work for me. The response time from me requesting the work, to the work being completed, was the best I have ever had! They showed up on time, the communication was great, they are super efficient and they did a top quality job! Couldn't ask for anything more. Highly recommend these guys!
