Why is my RCD tripping when the system heats?

Commonly a leaking element or heat-damaged wiring. We insulation-test, replace parts and verify safety device operation.

Constant discharge from the relief line—normal?

A brief drip during heating is normal. Continuous flow points to a faulty TPR or over-temperature fault—book a service.

Repair or replace my cylinder?

If the tank leaks or is 10+ years old with recurring faults, replacement is often more economical. Otherwise element/thermostat/valve repairs are cost-effective.

FAQ – Electric Hot Water (Southport)

Do you fix controlled-load/off-peak issues?

Yes. We test Tariff 31/33 circuits, contactors and time clocks, and repair wiring or elements causing after-hours failures.

My RCD trips only when the unit heats—what’s broken?

Usually a leaking element or heat-damaged wiring. We IR-test, replace the failed component and confirm RCD operation.

There’s constant flow from the relief line—normal?

A brief drip while heating is normal. Continuous flow points to a faulty TPR or an over-temperature fault. We test and replace as needed.

Can you replace the sacrificial anode?

Absolutely. New magnesium anodes extend cylinder life and reduce odour/colour issues. We also flush the tank if required.

Repair or replace—which way should I go?

If the tank leaks or the unit is 10+ years old with recurring faults, replacement is often cheaper long-term. Otherwise, targeted repairs (element/thermostat/valves) are cost-effective.
