Replacing a kitchen tap in Carlingford? Check the lead-free marking before you buy
A replacement kitchen tap needs more than the right colour and a connection that fits. Before buying lead-free tapware for your Carlingford home, check the product’s certification, its suitability for your water supply and whether the installation can be completed without changing the surrounding pipework. That quick check can save a return trip to the shop. A bargain mixer is less appealing when the plumber arrives and discovers missing parts, unsuitable connections or a model that cannot be verified.
Key takeaways
- Verify the exact product, not just a lead-free claim in the advertisement.
- Photograph the existing installation before choosing a replacement.
- Clarify access, isolation valves and quote exclusions before booking.

What changed for drinking-water products?
NSW Government advice updated on 28 October 2026 confirms that the installation transition for applicable copper-alloy drinking-water products continues until 30 April 2028. From 1 May 2028, applicable products installed in NSW must meet the lead-free requirements. During the transition, qualifying products must still have a current WaterMark licence and remain on the product database. Read the current NSW lead-free plumbing requirements.
This is a purchasing and installation check. It is not evidence that your existing tap has contaminated your water or needs immediate removal. Ask the installer to confirm the requirements applying to the proposed replacement.
Three things to send your plumber before ordering
1. The exact product details
Send the manufacturer, model number and product listing, rather than a screenshot showing only the price. Certification relates to the product, not simply the shop selling it. If the listing is vague, ask the supplier for the supporting documentation before paying.
2. Photos above and below the sink
One photo should show the tap and sink holes. Another should show the accessible connections underneath. Move cleaning products out of the way, but leave pipes and valves alone. A deep sink, narrow cupboard or fixed shelf can affect access even when the new mixer looks identical from above.
3. What you want fixed
Tell us whether the tap drips, swivels loosely, delivers poor flow or has damaged hoses. These are different problems. Replacing a mixer will not necessarily fix a restriction elsewhere in the supply, so it helps to explain what happens at other taps as well.
What should the installation quote cover?
Ask whether the price includes removing the old tap, fitting the replacement, reconnecting the supply and checking for leaks. Clarify who supplies the tap and what happens if an existing isolation valve will not shut properly.
A good quote also identifies exclusions. Altering a stone benchtop, changing the sink or repairing water-damaged cabinetry may involve separate work. Getting those boundaries clear beforehand makes the booking much less of a guessing game.

Keep the paperwork with the product
Save the invoice, model details and installation record in one place. They are useful if a cartridge needs replacing later or you need to identify the installed product. Avoid relying on the packaging staying in the garage for years.
We would rather check a proposed tap before it arrives than have you discover a compatibility problem halfway through the job. Send the model details with your enquiry and explain whether you need supply and installation or installation only.
Check the installation date as well as the label
For a kitchen tap purchase, distinguish the product's certification from the rules applying on the installation date. NSW's updated advice permits qualifying transitional products until 30 April 2028, with applicable lead-free installation requirements from 1 May 2028. Confirm the exact model's current WaterMark listing before buying, particularly for work planned well ahead.

Frequently asked questions
Does lead-free mean my old tap must come out?
Not automatically. The product transition does not diagnose the condition of your existing installation. Ask about your particular tap and proposed work.
Can I supply my own mixer?
Ask before purchasing. Send the exact model so compatibility, certification and the scope of installation can be checked.
Is WaterMark the same as a water-efficiency rating?
No. WaterMark concerns applicable product certification; a WELS rating describes water efficiency. Check both where required for the particular tap.
What is the current NSW lead-free installation deadline?
NSW's October 2026 advice sets 1 May 2028 for applicable lead-free installation requirements. Transitional products must retain a current WaterMark licence and database listing.
Does the tap need to match the existing sink holes?
Yes. Hole size, spacing, spout reach and clearance all affect fit. Send the model and sink details before ordering.
Can a pull-out mixer fit any cupboard?
Not always. The hose and weight need unobstructed movement beneath the sink; shelves and stored items can interfere.
Why check the isolation valves before fitting the tap?
A valve that does not shut properly can change the installation scope. Ask how water isolation and any necessary valve work will be handled.
Will a new mixer stop a leak beneath the sink?
Only if the leak comes from the mixer or its connections. Waste pipes and nearby appliance connections need separate assessment.
What happens if the supplied tap does not fit?
Agree on compatibility checks and responsibility before booking. Alterations, another visit or a different product may be needed.
Which documents should I keep?
Keep the model number, supplier invoice, certification details and installation record together so future parts and warranty enquiries are easier.
Conclusion
Check the exact tap model before buying, then confirm that its certification, connections and installation scope suit your kitchen. That is a more useful starting point than colour or price alone.
