Water, sewer & backflow
Central Coast Council supplies water and sewer here, and backflow test reports are lodged with Council. What the annual backflow test involves
We check each Gwandalan property for a natural gas connection or LPG cylinders before quoting gas hot water or cooktop installs, rather than assuming either.
Josh holds the gas licence as well as the plumbing licence, so the gas connection and the compliance certificate are part of the same job.
Nearby job: LPG cylinders in Mannering Park
We repair, replace and install gas, electric, heat pump and continuous-flow hot water units in Gwandalan, and take the old unit away. No-hot-water jobs are attended around the clock.
We clear blocked sinks, toilets and sewers in Gwandalan with the jetter or the drain machine, and put a camera down a drain that keeps blocking.
On the Central Coast the owner looks after the sewer pipes up to and including the point of connection, which takes in the boundary shaft and overflow gully. If the boundary shaft is flooded or a neighbour has the same problem, it may be Council’s, so call Central Coast Council on 02 4306 7900 before booking a plumber.

Customer feedback
We had our hot water system blow out while we were away for the weekend and came home to an absolute mess on a Sunday afternoon ! We contacted Donza Plumbing and within 24 hours Josh had us up an running again with a brand new install. His professionalism is commendable and we highly recommended Donza plumbing. Thanks Josh!
Thanks to the amazing Josh who came to our rescue on a dark rainy Sunday night. Sorted the problem and averted a flood.
