From Old Sink Out to Leak Test
A sink connection runs from the two supply lines and their isolation valves, through the tap, down through the basket waste, the trap and the waste pipe, and finishes with a leak test.
Supply lines
hot and cold lines feed the tap, and an isolation valve on each line lets you shut the water at the sink alone.
Basket waste
the fitting that seals the drain hole in the bowl and carries water out.
Trap
the bent pipe below holds a water seal, which stops sewer gas rising back through the waste.
Leak test
every connection gets run and checked with the cupboard open before we call the job done.
Where a dishwasher drains through the sink waste, the hose joins at a spigot, so a replacement waste needs one if a machine is plumbed in. Our dishwasher installation page covers the machine side of that work.

Who May Fit a Kitchen Sink in Queensland
A licensed plumber must connect a kitchen sink in Queensland, whether the job is a new bowl, a moved bowl or a like-for-like replacement. The QBCC lists fixing and replacing sinks as regulated work, and sinks sit outside its short unregulated list.
The rules split the work into two categories:
Notifiable work
installing a new sink, or moving one, in a building that already exists. No council permit applies, and the plumber reports the job to the QBCC on a Form 4 within 10 business days of finishing.
Minor work
replacing an existing sink in the same position. A QBCC licensee still does it, with no permit and nothing to lodge.
The owner keeps a copy of the Form 4 with the paperwork, and a register search through the commission confirms both the licence and any form lodged at the address.

Drop-In and Undermount Sinks Compared
A drop-in sink rests on its rim over the cut-out, while an undermount sits beneath the benchtop and needs an exact, sealed cut-out. That single difference drives most of the fitting work.
Drop-in
the rim covers the edges of the hole, so a rough cut stays hidden. This style suits laminate benchtops and goes in faster.
Undermount
clips or support brackets carry the bowl's weight from below, and the cut-out edge stays on show, so the edge wants a precise finish sealed with silicone.
Replacing a kitchen sink often means matching the old style, because a drop-in bowl will not cover a cut-out that was made for an undermount, and the reverse leaves a gap.

Like for Like or a New Position
Where the bowl goes sets the price, along with any new supply or waste points, the room to work under the bench, the benchtop itself, and the tap and fittings you choose. Once we have seen the job, the figure lands in a fixed quote, so nothing gets added later.
The housing stock shapes those factors here. Census figures put units and apartments well ahead of detached houses in this suburb, and area-level approvals added only 24 dwellings across five years, so most kitchens sit inside stock that is decades old.
Timber houses around Haig Road that kept their original plumbing often run galvanised branches beneath the floorboards. That steel rusts from the inside, so flow at a new mixer can disappoint until the branch is renewed. We check that before we quote, not after.
Tapware, wastes and connectors fitted in Australia also need WaterMark certification, so we work with products that carry the mark and sit on the product database. If the mixer is due for a change at the same time, our tap replacement page sets out the options. The braided hoses under a sink get their own attention on our flexi hose replacement page.

Trap, Waste and Seal Problems
Leaks under a kitchen sink usually start at one of five points. The trap or a waste joint, the basket waste seal, the tap base, a supply join, or the rim seal against the benchtop. A soft cupboard floor, a musty smell or a water mark underneath points to a slow leak even when nothing drips on the day we look.
Each fault has its own fix, and most are one-visit repairs:
- A weeping trap or waste joint needs the nut reseated or the washer renewed.
- A leaking basket waste seal means the bowl comes out or the waste gets refitted.
- A tap base leak traces to the body or the connections above the bench.
- A failed supply join is a quick renewal, and the isolation valves make it safe.
- A broken sink-to-benchtop seal gets cleaned back and redone.
Blockages are a different job with a different page: our blocked drains service handles them. For everything above the floor, the kitchen and laundry plumbing page lists the full range.

Kitchen Sink Questions From Auchenflower
Call (07) 3523 6417Can I install a kitchen sink myself in Auchenflower?
No, the plumbing connections are licensed work. The QBCC keeps only a short unregulated list, covering jobs like a tap washer or jumper valve, and sinks sit outside it. A licensed plumber runs the whole connection and tests it for leaks.
What is a Form 4 for a new kitchen sink?
A Form 4 is the notice your plumber lodges with the QBCC within 10 business days of finishing notifiable work, such as installing or relocating a sink. You receive a copy of the form for your records. A straight swap in the same position is minor work and needs no Form 4.
How do I check my plumber is licensed?
Search the QBCC's online registers. They show whether a plumber holds a current licence, and you can also see whether a Form 4 has been lodged for your address. The check takes minutes and settles it before work starts.
Why is water leaking under my kitchen sink?
Five points cause most of these leaks: the trap or a waste joint, the basket waste seal, the tap base, a supply join, and the rim seal against the benchtop. A soft cupboard floor or a musty smell points to a slow leak even without a visible drip.
Who arranges a kitchen sink replacement in an Auchenflower rental?
The owner or property manager holds the duty to keep the place in good repair, so a tenant reports the fault and the owner arranges the work. A tenant who wants the sink upgraded needs written approval on a Form 23 first, and that request cannot be refused without good reason.
