The wider Keperra plumbing catalogue covers every room of the house, and the kitchen and laundry guide gives the full picture of that part of the property. A new mixer while the bench is open is on the tap replacement page.
Wastes, Traps and Valves Under the Bench
Under the bench, our plumbers join the sink to the house: a hot and a cold line with valves, the tap, a basket waste, a trap and a waste pipe. Every connection gets a leak test before we finish.
What each piece of the kitchen sink plumbing does:
Isolation valves
one per supply line stops flow to the bowl alone, so taps elsewhere in the house keep running during the job.
Basket waste
the fitting sealed into the bowl's drain opening, carrying water down into the waste line.
Trap
the bent section that stays full of water, keeping sewer smells out of the kitchen.
Supply connections
the lines running from the valves to the tap tails. Old braided hoses there are worth swapping while the cupboard is empty, and the flexi hose replacement page explains why.
Leak test
water on, every joint watched, nothing signed off until each one stays dry.
Leaks Under the Sink and Around the Tap
Leaks under a kitchen sink come from five places: the trap or a waste joint, the basket waste seal, a supply join, the tap base and the rim seal.
Each spot has its own tell:
- A weeping trap joint drips from the lowest bend in the waste run.
- A failed basket waste seal shows as water seeping around the strainer into the cupboard below.
- A loose tap base sends water down the bench rather than into the bowl.
- A supply connection weeps from the moment the valves are opened.
- A broken rim seal lets washing-up water creep under the bench edge.
Watch for a cupboard floor gone spongy, a smell you can't place or a tide mark on the carcass. Any of those points to a slow drip even when nothing's visibly running.
Who May Fit a Kitchen Sink in Queensland
In Queensland, sink connections belong to a licensed plumber. Installing a fresh bowl, or shifting the old one, is notifiable work: council approval isn't needed, and the plumber lodges a Form 4 with the QBCC. The lodgement falls due within ten business days of finishing, and you receive a copy for your records.
Swapping like for like in the original position counts as minor work: a QBCC licensee does it, with no permit and no paperwork to file. Queensland tenancy law requires the owner's or manager's written sign-off on a Form 23 before a renter attaches a fixture, and a request shouldn't be refused without good reason.
Apartment owners should check with us first, because some unit jobs are trickier and need council approval. Adding a fixture to a building on a combined drain is permit work as well, and the council application goes in before the job starts.
Drop-In and Undermount Sinks Compared
A drop-in sink rests on its rim over the bench cut-out; an undermount sink is fixed below the benchtop, so the cut edge is on show and needs precision and a silicone seal.
Clips or support brackets bear the undermount's weight, which is why stone and solid tops suit that style. A drop-in hides a rough cut, suits laminate and lifts straight out at replacement time. Neither style changes the plumbing beneath: supply, waste and trap read the same either way.
Like for Like or a New Position
Five things shape the figure: whether the bowl stays in place, whether new supply or waste points are needed, the room under the bench, the benchtop material and the tapware.
A straight swap with everything staying put sits at the simple end of the range. Moving the bowl brings new pipe runs and a Form 4 on completion. The price is agreed in writing before any work starts, once we've inspected the job, and nothing begins without your go-ahead.
What Local Kitchens Usually Need
Area-level approvals ran to just 11 dwellings in 2021-22, so a sink job here is nearly always a replacement in a standing kitchen rather than a fit-out in a new build. That keeps most jobs in the minor-work lane: no permit, nothing to lodge.
A postwar cottage off Dallas Parade can hide a cramped cupboard with pipe runs from an earlier decade, and tight bench space adds time to a swap. A bowl that won't drain is a blockage rather than a sink fault, and the blocked drains page has that side of things.

Kitchen Sink Questions From Keperra Homes
Call (07) 3523 7121Can I put in a kitchen sink myself in Queensland?
No, you can't. Sink connections are licensed work, and the QBCC's short unregulated list for home owners covers small items like a tap washer or jumper valve, not a sink.
How do I check a plumber's licence before booking in Keperra?
Search the QBCC register online before you book. It confirms the licence is current, and it also shows any Form 4 lodged for the property after notifiable work.
Is a drop-in or undermount sink easier to fit in Keperra?
Yes, the drop-in. Its lip rests over the bench and hides a rough cut, which suits laminate tops. An undermount hangs under the bench on clips or brackets, so the opening has to be exact and the edge sealed with silicone.
Why is water pooling in my Keperra kitchen cupboard?
Usually one of the joints or seals under the bench: the trap, the basket waste, the tap base, a supply join or the rim seal. A cupboard floor gone soft, or a smell you can't place, usually means a slow drip running unseen.
Does my dishwasher drain through the kitchen sink?
Yes, in most homes. The machine's hose drains through a spigot on the sink waste, so any replacement waste carries one if a machine's connected. Our dishwasher installation page has the connection detail.
