Water, sewer & backflow
Hunter Water supplies water and sewer here, and backflow test reports are lodged with Hunter Water. What the annual backflow test involves
Balcolyn sits on a Lake Macquarie peninsula east of Morisset, so each address gets a check for natural gas or LPG before we quote gas hot water or cooktop work.
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.
We repair, replace and install gas, electric, heat pump and continuous-flow hot water units in Balcolyn, and take the old unit away. No-hot-water jobs are attended around the clock.
Common in Balcolyn
We clear blocked sinks, toilets and sewers in Balcolyn with the jetter or the drain machine, and put a camera down a drain that keeps blocking.
In Hunter Water’s area the owner looks after the sewer pipes up to where they join Hunter Water’s system, including the boundary trap and inspection shaft. If the inspection shaft is full or overflowing, the blockage may be in Hunter Water’s main, so call Hunter Water on 1300 657 000 (24/7) first.

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.
