Reliable System Care
Installing or servicing a hot water system in Cessnock involves more than swapping out a tank or turning a valve. Subat Plumbing Services takes the time to understand each property’s water usage, layout and plumbing setup to recommend systems that align with household or business needs. From selecting a suitable capacity to ensuring pipework compatibility, each step is approached with care and attention to detail.
For repairs, the process starts with a system inspection. Common issues include thermostat failure, valve leaks, or build-up inside the tank affecting water quality and flow. The team uses reliable diagnostic tools to pinpoint the fault and suggest repair or replacement options accordingly. Safety is prioritised throughout, particularly when dealing with electrical components or gas connections. Once work is completed, the plumber ensures all functions are restored and checks for compliance with relevant plumbing standards.

Maintenance and follow-up advice are also available, helping Cessnock locals keep their system in good working order.
What size hot water system do I need?
The right system size depends on household size, water usage habits and energy preferences. For example, a small household may be fine with a 125L electric system, while a larger family could require 250L or more. Instantaneous systems are popular for space-saving and continuous supply, but need to be sized by flow rate and usage points. A licensed plumber can assess your setup and recommend a unit based on demand, peak usage periods, and available power or gas supply.
How often should a hot water system be serviced?
Hot water systems should be serviced every few years, depending on the system type and usage levels. Regular servicing helps to flush out sediment, check valves, inspect for corrosion, and confirm that the thermostat and heating elements are working correctly. Some components, like anode rods in storage tanks, may need replacement after a few years. Regular maintenance helps extend the lifespan of the system and maintain energy efficiency.
What are signs my hot water system needs repair?
Common signs include fluctuating water temperatures, low hot water pressure, unusual noises (like rumbling or banging), water discolouration, or visible leaks near the unit. Inconsistent hot water can point to thermostat failure or sediment buildup, while leaks might indicate valve issues or tank damage. It's best to have the system inspected by a plumber as soon as these symptoms appear to prevent further deterioration.
