Leak Detection in Mangawhai

A water tank level that falls without obvious use can leave you wondering whether the water is escaping from the tank or somewhere along the supply.

How it works

  1. Call or enquire

    Phone us or send the address and what you’re seeing.

  2. We assess

    A licensed Stately plumber looks at the job on site.

  3. Clear quote

    You get a plain explanation and a clear quote before work starts.

  4. Job done and tidied

    We finish the work and leave the site clean.

Start by noting the level, the time and whether the pump runs while every outlet is off. Stately covers Mangawhai, and we investigate the tank, accessible connections and connected pipework in a planned sequence. The aim is to narrow down where water is going before recommending access work or a repair.

Record the fall before changing anything

Use the same safe viewing point or installed level indicator for each reading. Record rainfall, any tank filling and ordinary household use between checks. A photograph of the indicator can help show the pattern, although a faulty or sticking gauge could also give a misleading impression of water loss.

Check whether irrigation, an animal trough or an automatic filling arrangement draws from the tank. Look for dripping outdoor taps and listen for toilets refilling. Keep tank lids secured, stay out of the tank and avoid climbing up to inspect it. Tell us about anything you cannot safely see.

Check the tank and pump first

Onsite, we compare your observations with the accessible tank fittings, outlet connection, overflow and pump arrangement. Dampness around a connection is useful evidence, but it needs checking against recent rain or spillage. We also look at whether the indicated level agrees with any other safe means of checking it.

A pump starting when no tap is open can point towards pressure loss on the supplied side. It is a clue rather than proof of an underground leak: pump controls or a nonreturn valve could need attention too. We check how the system behaves before deciding which branch to investigate.

Use isolation to narrow the search

Where suitable valves are accessible, we can separate the tank outlet, pump supply and downstream branches in a controlled sequence. Comparing level or pressure behaviour across those checks helps distinguish possible tank leakage from water escaping through connected pipework. Some systems need temporary test connections.

We explain any interruption to the water supply before isolating it. Do not force stiff valves or switch unfamiliar pump controls yourself. If the tank is approaching empty, let us know before testing; the pump may need to be stopped safely to protect it from running dry.

Confirm findings before choosing a repair

Once testing points to a particular area, we explain what supports that finding and what remains uncertain. Accessible fittings may allow direct confirmation. A concealed supply line could require targeted detection followed by opening a small area, with permission, to inspect the suspected fault.

The repair depends on what is exposed and its condition. A leaking tank fitting calls for a different approach from a damaged underground feed. Where the supply line needs work, water main repairs may be appropriate. We discuss the proposed repair and access requirements before proceeding.

Recheck the supply and hand over

After an agreed repair, we restore the relevant supply and repeat suitable checks. That can include watching pressure behaviour, checking the repaired connection and comparing tank readings over a quiet period. Rainfall or water use during that period needs recording so the comparison remains useful.

You receive a clear account of what was checked, what was found and any areas still needing investigation. We explain which valves or controls were changed and how the system was left. Keep monitoring the level afterwards, and report further unexplained drops rather than treating one steady reading as conclusive.

Leak detection: questions from Mangawhai

Should I turn the pump off?

If water is running away visibly or the tank is nearly empty, contact us for advice. Only use a familiar, safely accessible pump switch; do not open electrical covers.

Can a tank leak with no wet patch?

Yes. Water could escape beneath the tank or from concealed pipework without leaving an obvious surface patch. Isolation checks help narrow the possibilities before access is planned.

What should I have ready when I call?

Have your level readings, approximate times and notes about pump cycling ready. Tell us about recent rainfall, automatic water users and access to the tank and pump.
