FAQs: Water Heater Repair or Replace
Typical lifespans: gas tank ~10 years, electric tank ~12 years, and tankless 15–20+ with regular descaling. Hard water and skipped maintenance shorten life.
Active leak/corrosion, or at/past typical lifespan with recurring issues → replace. Otherwise, repair often makes sense.
Turn the gas/electric supply off and close the cold-water shut-off to the tank. An active tank leak usually means replace now. For urgent help, use Emergency Plumbing
Yes. It factors common tankless issues (scale, error codes, ignition problems) and typical lifespans. Many tankless issues are repairable with descaling or sensor/service.
Check the data label. Most brands encode the manufacture date in the serial number. If unsure, upload a photo when you Book Online and we’ll confirm.
Electric elements/thermostats, gas control valves/igniters, anode rod replacement (for rust-coloured hot water), T&P valve, and sediment flush/descaling for rumbling or slow recovery.
Rust-coloured hot water often means the anode rod is depleted (repairable if the tank isn’t too old). A sulphur/“rotten egg” odour usually points to bacteria reacting with the anode—flushing, disinfecting, or changing anode type can help.
Stick to a simple plan: annual flush (tank) or annual descale (tankless), test the T&P valve, inspect/replace the anode rod every few years, and keep temps around 49 °C (120 °F) for safety/efficiency. These basics reduce sediment, corrosion, and unnecessary energy use—often adding years of reliable service.
