CID Pro Tips / Geysers

My geyser is leaking. What should I do first?

By CID Home Repairs and Services · Published

Start here

Keep clear of hot water, wet electrical fittings and a sagging ceiling. If the distribution board is dry and safely reachable, switch off the clearly identified geyser circuit. Isolate the water supply only if you know how to do so safely, then arrange professional assistance.

When to get professional help

Do not touch a wet distribution board or attempt valve, thermostat or element repairs. If there is immediate electrical or structural danger, move to safety and contact emergency services.

What have you noticed?

These clues help explain the problem. They do not confirm its cause.

What you seeWhat to report
Some discharge while water heatsA relief outlet can release expansion water.
A constant or heavy flowThe system needs professional inspection.
Water from the tank area or ceilingTreat this as an urgent leak, not a normal drip.

What you can do now

  1. Keep people out from under wet or bulging ceilings. Do not climb into the roof to inspect a leaking geyser.
  2. Leave every safety and relief outlet open. Never cap, plug or tie off a pipe to stop a discharge.
  3. From a safe position, note where water is visible and tell the plumber whether the power and water have been isolated.

Details that help us arrange the repair

  • Where the water is appearing and whether the flow is constant.
  • Any ceiling damage, hot water or nearby electrical fittings.
  • The geyser type and age if already known; do not climb up to find them.

If you rent or live in a managed building, notify the owner or property manager and agree the arrangements before authorising work. Take photos only where it is safe; you can share them when CID follows up.

What affects the repair cost?

A valve problem and a leaking tank are different repairs. Ask for the fault diagnosis, repair-versus-replacement options and the scope of any water-damage work.

Questions before you book

Should I block the overflow pipe?

No. A relief outlet is a safety feature. Blocking it can create a dangerous pressure situation.

Can I keep the geyser switched on?

With a suspected leak, keep it isolated until a qualified professional confirms it is safe to operate. Do not approach wet electrical controls.
