Charlestown at a glance, for plumbing
Pressure management since March 2026
Hunter Water gradually reduced water pressure in parts of Charlestown in March 2026. Its program targets areas where pressure is very high, because that can burst mains and damage household plumbing.
Named by three sewage plants
Hunter Water names Charlestown on the service lists of three treatment works: Burwood Beach, Edgeworth and Belmont. Whichever plant your street drains to, the main is Hunter Water's.
Hallam and Tiral streets
Both are on Lake Macquarie City Council's 2025-2026 list of drainage improvement works, paid for by its stormwater management charge.
Owner-occupied, mostly
The 2021 Census counted 76.0% separate houses in the suburb, 14.9% semis, terraces or townhouses and 8.9% flats. 34.6% of homes were owned outright, 37.4% with a mortgage and 26.2% rented, below the NSW figure of 32.6%.
What the pressure change means at home
Hunter Water lowered the pressure slowly, over a six-week period, and says most households won't notice. It expects washing machines, dishwashers and hot water systems to keep working normally.
Two groups were asked to get in touch: homes with a dialysis machine, and properties with fire hydrants, hose reels or sprinklers. If either applies to you and you haven't spoken to Hunter Water, do that before calling a plumber.
If a tap or shower seems weaker
- Check whether it's one fitting or the whole house. One weak shower often points to the fitting itself, not the mains.
- Look at the meter with every tap off. If the dial still moves, you may have a leak on your side. Our leak check tool walks you through it.
- Listen for banging when taps shut. That's water hammer, a separate fault worth naming when you book.
- Ask your neighbours. If the whole street changed at once, Hunter Water is the first call.
Your pipes start at the main
Hunter Water makes the owner responsible for the water pipes and fittings inside the property, starting where they join its main, and for any damage a failure causes. As a service it may look after the path tap and meter, but only within the first metre of pipe past your boundary. Beyond that, a leak under the lawn or the slab is yours to find and fix.
What we would do
Note when the change started and which fittings are affected before anyone visits. If the whole house dropped at once around March 2026, Hunter Water's pressure work is the likely reason, and it expects appliances to cope. One weak fitting, a meter that keeps turning, or new noises in the pipes are worth a plumber who specialises in pressure and leak work.
