    Signs You Need a Hot Water Replacement

    If you notice any of the issues below, replacement is usually the best option:

    • Hot water system older than 10–12 years
    • Rust-coloured or brown water
    • Tank leaking from the bottom
    • Burst or cracked tank
    • Rumbling or popping noises from the tank
    • Water running out much faster than usual
    • Frequent repairs in the last 12 months
    • Pilot light repeatedly failing
    • High energy bills for no reason
    • Severe corrosion on valves or fittings

    A failing system can cost more to run than a new one.
