Family-owned plumbing, Central Coast to Newcastle.

Yes. Donza Plumbing is run by Josh, a licensed plumber and gas fitter, and the business carries $20 million public liability cover (Donza Plumbing Pty Ltd, ABN 51 697 209 153). The gas part matters: gas work is separately licensed in NSW, so we can legally handle gas appliances and hot water that plumbing-only operators cannot. Every job is left compliant to AS/NZS 3500 and, for gas, AS/NZS 5601.

In NSW, plumbing and gas fitting are licensed separately, and plenty of plumbers are not authorised to touch gas. Josh holds both, so for gas hot water, cooktops, heaters and leaks you get one licensed tradesperson who can do the whole job, certify it, and not subcontract the gas out. That is the work a plumbing-only operator has to turn away.

Under 8 years old with a failed valve or element, repair is usually worth it. Older than 10 years, or a leaking tank, and replacement is the honest answer. We quote both options and the running-cost difference, including whether a heat-pump rebate applies, so you can make the call on real numbers.

The plumbing side of it, end to end: drainage set-out and core-holes through slab, in-wall cistern and bath rough-ins, then back for the fit-off once tiling is done. We work in with your builder and tiler, and after enough bathrooms together, we can also bring trades we already trust. It is the work our Instagram is full of.

Most household blockages clear in a single visit with a jetter or drain machine. If a drain keeps blocking we run a CCTV camera through it so you know whether it is tree roots, a collapsed section or just buildup, and exactly what fixing it properly costs.

We're based in Mannering Park and cover Newcastle, the Central Coast, Lake Macquarie and the Hunter, still servicing Lake Munmorah and the lakes corridor. Summerland Point, Gwandalan, Budgewoi, Toukley, Woongarrah, Morisset, Swansea and the suburbs between. If you're just outside that and not sure, ask.

Yes. Burst pipes, overflowing sewers and no-hot-water jobs are quoted before we leave and attended around the clock. The after-hours rate is agreed on the phone, not after we turn up.

Yes. Accessibility bathrooms are part of the renovation work: set-outs for hobless showers, in-wall cisterns, grab-rail backing and floor wastes that meet the layout the OT and builder are working to. We quote the plumbing against those drawings before the room is stripped.
