Leaking tap: repair it or replace it?
Repair is worth discussing when the tap body is serviceable and the correct replacement part is available. Replacement becomes a stronger option when the fitting itself is damaged, suitable parts cannot be sourced or you want a different setup. Start by locating the leak and identifying the tap, rather than buying a replacement on appearance alone. Ask about tap and mixer repairs with the details.

The short answer
- Identify the fitting and the leak location.
- Check genuine parts and product compatibility.
- Keep permitted tap work separate from pipework.
Locate the water before choosing parts
A tap and mixer repair enquiry should explain whether the drip comes from the outlet with the control closed, around a handle, at the base or beneath the bench. Include a photograph of the complete fitting and the area below it. Those locations give the person investigating a better starting point than a request to replace whichever component you have heard commonly wears out.
Note when the leak occurs: with the fitting closed, only while running or after water has been splashed around the base. Dry accessible surfaces and record what you have already observed; you do not need to dismantle the fitting to prepare an enquiry. If there are brand markings, photograph them along with any model details in your purchase records. Avoid selecting a cartridge merely because its shape looks familiar online.
Ask the repairer to identify the failed component and explain the condition of the surrounding fitting. The repair decision should address both the immediate leak and whether the rest of the tap is suitable to retain. Request a clear distinction between a confirmed defect and a component that still needs inspection. That makes it easier to understand why a repair or replacement is being proposed.
If the water source is unclear beneath a sink, use the water-leak checking guide to organise the description before the visit. Keep photographs of the surrounding cupboard and nearby connections, not just the tap above the bench. Explain any recent work in the area. The aim is to locate the source before a new fitting is ordered and the original symptom remains unresolved.
Understand the homeowner repair allowance accurately
The Plumbers, Gasfitters and Drainlayers Board says homeowners can replace or repair taps, ball cocks and plugs, and install appliances such as dishwashers and washing machines. Its consumer advice also sets a boundary: homeowners cannot undertake work fixing or unfixing supply pipes, traps, wastes and the other pipework and fixtures it lists. The tap allowance is specific; it is not general permission to alter the plumbing around it.
For a tap job, check the actual tasks rather than treating the word replacement as a complete description of what is allowed. If the work reaches supply-pipe alterations, waste connections or another excluded activity, engage an appropriately licensed plumber for that work. Ask the Board for clarification when the boundary is unclear. A retailer’s description of a fitting as easy to install is not the same as legal authorisation for every connection involved.
Permitted work also needs a suitable method. Methven’s basin-mixer installation instructions begin with turning off the water supply and include checking connections for leaks afterwards. Use the instructions for your actual product and stop if you cannot carry out the required preparation confidently. An allowance to repair a tap does not make an unfamiliar fitting, seized component or unclear isolation arrangement a sensible first project.
You can choose professional help even for work inside the homeowner allowance. Ask the plumber to explain the diagnosis, show the proposed component and check the fitting after repair. For restricted plumbing work, the Board recommends checking the current practising licence. Keep the scope clear so you know whether the visit covers the tap itself, a connection problem or additional work discovered during the inspection.
Compare a defined repair with a compatible replacement
For repair, ask whether the correct service part is available and how it will be identified. Provide the manufacturer and model information you have rather than ordering a near match yourself. Ask whether the quoted work includes investigation, the part and a check after reassembly. If inspection reveals damage beyond the initial component, agree that the repairer will discuss the revised scope before continuing. Older taps often use washers, while many modern mixers use ceramic cartridges. Ask the repairer which mechanism your fitting has and whether the correct part is available; do not buy a cartridge by shape alone. The tap’s model and manufacturer instructions determine the suitable repair.
For replacement, ask the installer to check the proposed fitting against the existing supply arrangement and mounting surface. Methven’s product instructions specify operating conditions and connection requirements for each fitting. A tap that fits the hole still needs to suit its intended installation. If the current hot-water arrangement is unclear, the low-pressure versus mains-pressure guide helps frame the compatibility questions to put to the plumber.
Keep functionality in the decision as well as appearance. Consider spout reach, handle access, nearby windows and whether the new fitting will work comfortably with the existing basin or sink. Photograph the surrounding space and explain what frustrates you about the current tap. Ask the installer to review the proposed product before you purchase it, particularly if you want to change the style or mounting arrangement.
Compare repair and replacement on the same basis. Ask what each option includes, what is excluded and how additional work would be authorised. Avoid comparing a loose part price with a complete installed replacement. The plumbing quote guide explains how attendance, investigation, materials and access can sit within a proposal. A useful comparison is a defined repair against a specified installed fitting, with the boundaries visible.
Finish with a checked fitting and useful records
Before the visit, clear the accessible cupboard so the repairer can see the area and protect your belongings. Keep the existing product paperwork nearby and explain any previous attempted repairs. If you have already bought a replacement, send its exact model before the appointment. Ask who is responsible for returning an unsuitable owner-supplied product and whether missing parts would require a separate visit.
At completion, ask what was replaced and how the repair was checked. Methven’s basin-mixer instructions require careful leak checks after the water is turned back on; use the corresponding instructions for the actual installed product. Ask the contractor to explain any outstanding concerns separately from the finished work. Retain the component or model details in your records so a future service enquiry begins with something more precise than a photograph.
Care should follow the finish and product instructions too. Methven advises warm soapy water and a soft damp cloth for the cited basin mixer, and warns against abrasive cleaners. Avoid escalating a cosmetic mark into a damaged finish with aggressive treatment. Keep the care sheet alongside the invoice, especially if the fitting has a finish or maintenance requirement that differs from the one it replaced.
When booking tap and mixer repairs, send the leak location, fitting photographs and model information together. Ask whether the first visit aims to diagnose, repair with an identified part or install an agreed replacement. A good decision leaves you knowing why the chosen option suited the fitting, what was checked and what records to keep. That is a firmer basis than replacing every dripping tap or repairing one indefinitely without reviewing its condition.
Common questions
Can a homeowner legally repair a tap in New Zealand?
PGDB permits replacing or repairing taps, ball cocks and plugs. Its exclusions still apply to supply pipes, wastes and other listed plumbing work. Clarify the actual tasks and use a licensed plumber for restricted work.
Do I need to replace the whole mixer for a drip?
Ask for the failed part to be identified first. Discuss whether the correct service part is available and whether the remaining fitting is suitable to retain before choosing a complete replacement.
Can I buy a new tap before the plumber visits?
Send the exact proposed model and existing installation photographs first. Ask the installer to check pressure compatibility, mounting and connections, and clarify responsibility if an owner-supplied fitting proves unsuitable.
What should the repair invoice record?
Ask for the fitting or component identity, work completed and any outstanding recommendations. Keep the invoice with the product instructions and earlier repair records so a repeat problem can be assessed in context.
