A Rheem gas hot water system manufactured in 1996, still going Steady, Hot and Strong!

We recently attended a customer’s property in Chatswood, on the Lower North Shore, to service their external Rheem gas hot water heater. Once on-site, we noticed that this hard-working tank had been operating reliably since 1996! The fact that this water heater is still going strong after nearly three decades of continuous use speaks volumes about two things:

The customer’s diligence with regular servicing and maintenance
Rheem’s reputation for building durable, Australian-made products

A simple repair of this Rheem gas hot water tank

Upon inspection, we found the TPR (temperature pressure relief) valve was leaking excessively. This is a common issue as hot water tanks age, as the valve plays a critical role in safely releasing excess pressure from the tank.

We replaced the faulty TRP valve and carried out a full service on the unit to ensure it continues to operate safely and efficiently.

The longevity of this particular unit is also a testament to our customer, who has been proactive about servicing and maintaining their hot water heater over the years. Regular servicing and maintenance helps prevent minor issues from turning into catastrophic failures and extend the life of the system considerably.

Simple DIY checks to keep your hot water running smoothly

While professional servicing is essential, there are a few basic maintenance checks homeowners can do every couple of months to ensure their hot water tank is in top shape:

Check for leaks – Look for drips or signs of corrosion around the tank, pipes, or valves. Catching small leaks early can prevent bigger problems.
Test the pressure relief valve – Gently lift the lever to ensure it discharges water for a few seconds and moves freely. Replace it if it’s stiff or unresponsive.
Monitor water temperature – Notice if your hot water feels cooler than usual, runs out too quickly, or becomes excessively hot — these are signs something’s not right.
Watch for ants – Ants sometimes nest around the base of the heater, particularly in colder months, which can interfere with electrical parts.
Keep the base clear – Remove weeds, grass, and soil buildup around the bottom of the tank to prevent moisture damage and rust.

These small tasks won’t replace a professional service but can help keep your system running smoothly between appointments.
