This page covers the sink itself: the supplies, the tap, the waste and the trap. It sits within our kitchen and laundry plumbing work, and it stops where the drains take over.
From Old Sink Out to Leak Test
Fitting a bowl means running two supplies up to the tap, one from the hot side and one from the cold. On the drain side, the outlet in the bowl feeds the trap and then the waste pipe, and the last step is a leak test. Each piece has a job:
Isolation valves
a small valve on each supply line shuts the water at the sink alone, so the rest of the house stays on.
The trap
it holds a plug of water in the waste that blocks sewer air from coming back through the drain.
The dishwasher spigot
where a machine drains through the sink waste, its hose pushes onto a spigot, so a replacement waste carries that fitting.
WaterMark
tapware, wastes and connectors all need certification and a listing on the product database.
Before we pack up, we run water through every new joint and check beneath the bench for weeps. The dishwasher installation page covers the machine's own water and waste connections.
What a Home Owner May Do Under the Sink
A licensed plumber has to make the connections under a Queensland kitchen sink. Putting in a new bowl, or shifting one, counts as notifiable work when the house is already built. No permit from council is needed, and we lodge a Form 4 with the QBCC inside 10 business days of finishing.
A like-for-like change in the one spot is minor work instead. A QBCC licensee still does it, but nothing gets lodged.
You keep a copy of the Form 4, and the QBCC's registers let you confirm both the licence and the lodged form online. The unregulated list is short: swapping a tap's jumper valve or washer is about the extent of it, and a sink never makes that list.
Apartment owners should raise it with us first, since some apartment jobs run heavier and require a council permit. Australian Bureau of Statistics area-level estimates put five-year population growth around 5.3 per cent, with 19 dwellings approved across 2021-22. Nearly every sink job we quote here goes into a home that was finished long ago.
Drop-In and Undermount Sinks Compared
A drop-in sink rests on its rim over the benchtop cut-out, whereas an undermount fixes underneath and needs a precise edge, sealed with silicone. The two suit different benches:
Drop-in
the rim hides a rough cut, so laminate benchtops are fair game and the fit runs simpler.
Undermount
brackets under the bench hold the bowl up, and the cut edge stays visible, so it has to be exact.
Either way
a silicone bead seals the join between sink and bench.
Like for Like or a New Position
Scope sets the price: same spot or a new position, any fresh water or waste point, the room under the bench, the benchtop itself, and the tap and fittings you choose. Once we've seen the job, the figure lands in a fixed quote, and it doesn't move after that.
The local angle matters here. Plenty of pre-war weatherboard homes around Ashgrove still carry galvanised steel supply lines inside the wall cavities, rusting from within. A sink change opens the cupboard and the wall behind it, which is the moment to find a corroded line before a pinhole soaks the lining boards.
Trap, Waste and Seal Problems
Most leaks under a kitchen sink come from five places:
- a joint on the trap or the waste
- the seal under the drain flange in the bowl
- the base of the tap itself
- a supply connection
- the rim seal where sink meets benchtop
A swollen cupboard floor, a musty odour or a water stain points to a slow leak, even when nothing drips on cue. The braided hoses feeding many sink mixers fail often too; our flexi hose replacement page covers them. A bowl that won't drain is a different fault, and it belongs with our blocked drains work.

Kitchen Sink Questions From Ashgrove Homes
Call (07) 3524 7137Can I install a kitchen sink myself in Ashgrove?
No, the connections under a kitchen sink are licensed work in Queensland. The QBCC's unregulated list only reaches small tap parts, such as a jumper valve or a washer, and a sink never appears on it.
How do I check my plumber is licensed?
The QBCC keeps online registers covering both licences and lodged Form 4s. Ask for the licence number when you book, then look it up and confirm the form is registered for your address.
Why is water leaking under my kitchen sink?
Usually one of five: a trap or waste joint, the drain-flange seal, the tap's base, a supply fitting, or the rim join at the benchtop. A swollen cupboard floor means a slow leak even with no drip in sight.
Who arranges a kitchen sink replacement in an Ashgrove rental?
The owner or manager must keep the place in good repair under Queensland tenancy law, so the replacement sits with them to arrange. A tenant needs written approval on a Form 23 before attaching a fixture or making a structural change.
Can a kitchen sink in Ashgrove be moved to a new spot?
Yes, shifting a sink within an existing building is notifiable work. A licensed plumber runs the fresh supply and waste lines and lodges a Form 4 with the QBCC within 10 business days.
