Leaking geyser: what to do first

A leaking geyser can damage ceilings, electrical fittings and surrounding building materials. The priority is to reduce immediate risk — not to diagnose or repair the geyser yourself.

Understand it. Make it safe. Get it fixed.

POSolve gives practical first steps and a clear point to stop and call a professional.

1. Check for immediate danger

Leave the area and get help immediately

If water is reaching electrical fittings, there is smoke, sparking, a burning smell, a collapsing ceiling, or anyone is in immediate danger, keep people away. In South Africa, call 112 from a mobile for an emergency.

2. Safe first steps

  1. Keep people away from wet ceilings, light fittings and electrical points.
  2. If the electrical distribution board is dry, safely accessible and you know which breaker supplies the geyser, switch that circuit off. Do not approach a wet or unsafe board.
  3. If you can safely identify the geyser water-isolation valve without climbing into a roof space or approaching the leak, close it.
  4. Place containers or towels only where it is safe to do so. Do not stand beneath a sagging or water-filled ceiling.

3. Do not do this

  • Do not open the geyser or remove covers.
  • Do not work on wiring, thermostats, elements or pressure valves yourself unless you are appropriately qualified.
  • Do not enter a wet roof space or climb onto a roof to inspect the leak.
  • Do not puncture a bulging ceiling to release water.

4. When professional help is needed

A leaking geyser normally needs professional inspection. A technician may need to determine whether the issue is the geyser tank, a valve, pipework, overflow, tray or another component. If the leak has affected ceilings or electrical systems, additional trades may also be required.
