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
Natural gas or LPG is confirmed at the property first in Chain Valley Bay, because the answer decides how we price 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.
Nearby job: LPG cylinders in Mannering Park
We repair, replace and install gas, electric, heat pump and continuous-flow hot water units in Chain Valley Bay, and take the old unit away. No-hot-water jobs are attended around the clock.
Jobs to plan for in Chain Valley Bay
We clear blocked sinks, toilets and sewers in Chain Valley Bay 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.

Jobs to book
Local context
Chain Valley Bay is a Central Coast Council suburb at the southern end of Lake Macquarie, next to Gwandalan and Summerland Point. You may see it written as Chain Valley Bay North or Chain Valley Bay South, but NSW Government mapping and the Census both show one suburb, and this page covers all of it. The 2021 Census counted 1,405 private dwellings: 90.1% of occupied dwellings were separate houses and 9.0% were semi-detached, row, terrace or townhouse dwellings. The Chain Valley Bay section of Lake Macquarie State Conservation Area keeps 272 hectares of bushland behind 600 metres of foreshore. Almost all of the suburb is inside the Swansea North Entrance Mine Subsidence District, where Subsidence Advisory NSW approval is needed before building or extending a home, so the plumbing for an extension is best planned alongside that approval.
Customer feedback
Thanks Josh for the installation of my new hot water system. A neat and extremely professional job. I appreciated your communication, reliability and punctuality. Gladly send more work your way.
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!
