Completion
It gives us a useful starting point, not a diagnosis. Tell Stately which basin activates the heater, what happens at the shower and whether anything has recently changed. Stately covers Mission Bay. Arrange an assessment rather than replacing the heater or shower fittings on the strength of that symptom alone.
Separate failure to start from cold delivery
First, describe what you already notice during normal use. Does the heater show that it has started, but the shower remains cold? Or does the heater stay inactive until the basin runs? Those are different observations. Mention any displayed fault message and whether the shower ever warms up.
A continuous flow heater responds to water passing through it. A basin activating it tells us something about that particular draw, but not whether every part is working correctly. We compare the shower behaviour with the basin behaviour and identify the heater model before choosing the next checks.
Follow the shower water path
The shower head, hose and mixer all belong in the assessment. A restriction or a change in the amount of hot water drawn can affect whether the heater starts. Tell us if the problem began after a new shower head, mixer replacement or bathroom work.
We check the available flow and how the mixer draws hot water, then compare that with the appliance requirements. The investigation may point towards a plumbing restriction, mixer servicing or an appliance fault. Repairing the relevant component is more useful than fitting a larger heater before the cause is established.

Check the appliance against the symptom
Have the appliance make, model and any previous service paperwork available. Confirm the gas supply at the address rather than inferring it from the suburb. Tell us whether the basin water stays hot or alternates between hot and cold, because starting and continuing to heat are separate observations.
A licensed gasfitter checks the appliance operation against its instructions and investigates any relevant fault indication. The basin result helps direct that work; it cannot prove the heater needs no attention. Any appliance repair or replacement should follow the findings, with replacement suitability checked against the actual shower demand.
Book an assessment, not a workaround
Include whether other showers are affected and whether the problem is constant or intermittent. If you have already noticed that opening the basin makes the shower warm, report it. That is useful evidence, not a solution that should become part of your daily shower routine.
Gas work must be done by a licensed gasfitter. Check the PGDB register, and do not open the appliance or adjust gas components yourself. If you smell gas, avoid flames and electrical switches, leave the area and call your gas supplier or emergency services from outside. Treat that separately from the shower fault.
Confirm the shower works at handover
After the agreed repair, we check the original symptom at the shower and compare it with the basin result. The handover should explain what was found, what was repaired or installed and how the heater now responds. Keep the appliance details and service record together for future enquiries.
For service or repair, we leave the applicable paperwork for the actual work. WorkSafe requires a Gas Safety Certificate for connected gas work and a Certificate of Compliance for general or high risk gasfitting. Ask which documents apply to the completed job, and keep them with the handover information. Keep the certification paperwork with your appliance records.
Gas fitter: questions from Mission Bay
Does hot water at the basin rule out a heater fault?
No. It shows the heater operates under that draw. The shower creates a different demand, so both the water path and appliance operation need checking.
Should I buy another shower head first?
Wait for the assessment. Give us the current shower head details and explain any recent change. A replacement needs to suit the shower and heater arrangement.
What should I record for an intermittent problem?
Note which outlet was running, whether the heater started and any displayed fault message. Describe observations from normal use rather than dismantling fittings to investigate.

Thomas was professional, fast and efficient. He explained things clearly, and honestly. We were about to leave for the South Island for the weekend, Thomas made sure the job was completed in good order before we left. He also checked-in with us periodically to ensure there were no further issues.
