Slow draining belongs on our blocked drains page rather than this one.
Wastes, Traps and Valves Under the Bench
A sink connection is five parts and a test: two supply lines with isolation valves, the tap, the basket waste, the trap and the waste pipe, all proven dry with a leak test.
Isolation valve
one per supply line, so you can shut the sink off alone without killing water elsewhere.
Basket waste
the fitting that plugs the drain hole in the bowl.
Trap
the bend holding a plug of water against sewer smells rising back up.
Supply connections
the hot and cold lines joining the tap.
Leak test
every joint run with the water on and checked against a dry towel.
Two extras matter here. Tapware, wastes and connectors fitted in Australia need WaterMark certification and a listing on the national product database.
Most dishwashers push their waste hose onto a spigot at the sink's waste fitting, so a replacement needs that spigot present. Dishwasher installation covers the rest of the machine's plumbing.
Kitchen Sink Work and the Form 4
Only a licensed plumber may connect a kitchen sink in Queensland. The QBCC's owner summary puts sink repairs and replacements among work reserved to a licensed plumber or drainer, and a sink does not appear on its short list of unregulated jobs.
Putting a new sink in, or shifting an old one, counts as notifiable work: no council permit applies, and we lodge a Form 4 with the QBCC inside 10 business days of wrapping up. The person who engaged us keeps a copy.
The QBCC's online registers let any owner check a licence, or see whether a Form 4 sits against an address. A like-for-like swap drops to minor work instead: a licensee still does it, but nothing gets lodged.
Drop-In and Undermount Sinks Compared
A drop-in sink rests on its rim over the cut-out, while an undermount fixes beneath the benchtop, so the cut edge shows and wants an exact, sealed opening.
Drop-in
the rim hides a rougher cut, laminate tops take it happily, and fitting is simpler.
Undermount
clips or support brackets carry the bowl's weight from below.
Cut-out
with an undermount the edge is on show, so the opening needs to be exact.
Silicone
a bead seals bowl to benchtop either way.
What Changes the Price of a Sink Job
Five things set the figure: where the new bowl sits, whether fresh water or waste points are needed, the room under the bench, the benchtop itself, and the tapware.
The figure lands in your written quote once one of our plumbers has seen the bench, and nothing starts before you approve it.
Same place
a straight swap keeps the old supplies and waste.
New points
shifting the bowl means new water and waste runs.
Access
tight cupboards slow everything down.
Benchtop
stone and laminate behave differently around the cut.
Tapware
a new mixer or waste set adds parts and time.
Swapping the mixer at the same time? Tap replacement covers the choice and the fit. Filter taps carry their own fitting rules, and water filter installation sets them out.
Second Kitchens on the Estate Streets
Suburban building rolled out here from the mid-1990s onward, so plenty of the houses fronting South Pine Road are now on their second bench, and a sink swap usually rides along with that work.
Under estate-age benches, the flexible braided connectors feeding the kitchen mixer are past their prime, and one that lets go inside a cupboard can drip for a whole morning unheard. We check them on every sink job, and flexi hose replacement covers the full swap.
Trap, Waste and Seal Problems
Leaks gather in five spots: a trap or waste joint, the waste seal inside the bowl, the mixer, a supply join, and the bead between bowl and bench.
Trap or waste joint
a slipped nut or tired washer we reseat.
Waste seal
the rubber plug in the bowl's drain hole gets renewed.
Mixer base
water tracking under the tap calls for a fresh O-ring.
Supply join
new thread and fibre stops the seep.
Bench bead
silicone renewed between bowl and benchtop.
Soft chipboard, a stale smell or staining on the cupboard floor under the bowl all mark a slow leak, even with no drip showing. Call us when any of those appear.

Kitchen Sink Questions
Call (07) 3524 7137How does a plumber fit a new kitchen sink?
We isolate the supply, remove the old bowl and mixer, then join both supply lines, the mixer, the waste fitting, a trap and the drain line, and finish with a leak test.
Can I install a kitchen sink myself in Queensland?
No, because the QBCC's owner summary reserves sink repairs and replacements for a licensed plumber or drainer. A sink never appears on its short list of unregulated jobs.
What is a Form 4 for a kitchen sink job?
A Form 4 is the notice a plumber lodges with the QBCC within 10 business days of finishing notifiable work. New and relocated sinks trigger one, and the person who engaged the work keeps a copy.
Who organises a sink replacement in a Warner rental?
The owner or manager carries the duty to keep rental premises in good repair, so they arrange the job. A tenant needs the owner's written approval on a Form 23 before any fixture goes on, and refusal needs proper grounds.
Does Unitywater or the council need to approve a new sink?
No. Unitywater runs the main, the meter and the sewer, and a sink job sits on the property side. A straight swap is minor work, a new or shifted sink is notifiable, and neither needs a council permit. Apartments and combined-drain homes can need one, so check with us.
