Your hot water system is one of the hardest-working appliances in your home. It heats, stores, and delivers water on demand — all while handling pressure, mineral build-up, and daily wear.
If you want it to last well beyond its warranty, regular maintenance is non-negotiable. Here’s how Bayside homeowners can keep their systems performing efficiently and avoid costly mid-winter breakdowns.
1. Replace the Sacrificial Anode Rod
Inside your tank is a small but crucial component — the anode rod. Its job is to attract corrosion and protect the steel walls of your system. Once it’s worn down, the tank itself starts rusting from the inside out.
Most rods need replacing every 3–5 years, depending on your water quality and usage. Skipping this step is the fastest way to shorten your system’s life.
2. Test the Temperature and Pressure Relief (TPR) Valve
The TPR valve is your hot water system’s safety release — it stops the tank from over-pressurising and exploding under heat stress.
Every six months, carefully lift the test lever. If water doesn’t flow (or keeps dripping after you release it), the valve may be faulty and needs replacing immediately.
A quick valve test today can prevent thousands in property damage later.
3. Inspect for Leaks and Corrosion Early
Even a small drip near the base of your system is a red flag. It often indicates early internal rust or failed seals. Don’t ignore it — catching a leak early can mean a simple repair instead of a full replacement.
Check regularly around fittings, joints, and the top cover for signs of moisture or corrosion.
4. Keep the Temperature Set Correctly
Water that’s too hot wears out internal components faster and costs more to heat. For most households, the ideal thermostat setting is 60–65°C — hot enough to prevent bacteria, but cool enough to protect your system.
If your water fluctuates or goes cold often, your thermostat or heating element might be failing. Our team can test both in minutes.
5. Schedule Regular Professional Servicing
A licensed plumber should inspect your system at least once a year to:
- Test and replace worn valves and seals
- Check the thermostat and heating element
- Confirm pressure and temperature compliance
Just like a car service, this proactive care prevents small issues from turning into expensive emergencies — and keeps your system efficient year-round.
6. Upgrade Before It Breaks
Even with great maintenance, most systems have a working life of 8–12 years (electric) or 10–15 years (gas). If yours is approaching that age, it’s smarter to plan a replacement before it fails.
A modern gas, electric, or heat pump system can deliver faster heating, lower energy use, and better warranty protection.
The Bayside Factor
Bayside’s coastal air and slightly mineralised water increase corrosion risk. Homes in Brighton, Sandringham, and Beaumaris are especially prone to rusted fittings and early valve wear.
That’s why annual inspections matter more here than almost anywhere else in Melbourne.
Ezy-Plumb services all major brands — Rheem, Rinnai, Dux, Bosch, and Thermann — using certified parts and local expertise to protect your system’s lifespan.
