Kitchen Plumbing - Sink, Dishwasher & Renovation Rough-In

Kitchen plumbing is where small jobs go wrong fast. A poorly seated waste fitting under a stone benchtop, an unsupported flexi hose behind a dishwasher, or a non-compliant gas cooktop connection can cost tens of thousands in water damage or insurance loss. Tradetek Solutions does kitchen plumbing properly across Sydney, the Central Coast and Newcastle - first time, signed off.

Our most common kitchen jobs in 2026: kitchen mixer tap replacement from $189 supplied and fitted, undermount or top-mount sink swap from $345 including waste and trap, dishwasher install from $245 with a dedicated isolation tap, instant boiling/chilled filtered water taps (Zip HydroTap, Billi, Quooker) from $385, and waste disposal units (InSinkErator) from $445.

Renovation rough-in and fit-off pricing in Sydney starts at $1,650 for a like-for-like kitchen with no relocation. Moving the sink to an island bench or adding a second water supply runs $2,400-$4,200 depending on slab depth and access. We coordinate directly with your cabinetmaker and stone benchtop installer so the cut-outs match the fittings on the day of install.

Gas cooktop connections require a NSW-licensed gasfitter, an AS/NZS 5601-compliant flexible connector, and a Certificate of Compliance for Gas (CCG) lodged with NSW Fair Trading. We supply the certificate same-day at no extra cost - which your home insurer (IAG, AAMI, Suncorp) will ask for if a future claim involves the gas point. Cooktop connection from $245.

All fittings used are WaterMark-certified and meet WELS efficiency ratings for taps and dishwashers. Workmanship is backed by a 12-month warranty and $20M public liability. We service Sydney metro from Sutherland through the Inner West, Eastern Suburbs, North Shore, Hills District and out to Penrith - same-day for swap jobs, scheduled for renovation rough-ins.
