What to Do When a Pipe Bursts: A 5-Minute Emergency Plan
24 May 2026 · Plumbers On Duty
Quick answer (the first 5 minutes)
- Minute 1: Turn off the main water valve
- Minute 2: Turn off the geyser at the DB
- Minute 3: Open the lowest cold tap to drain pressure
- Minute 4: Mop up standing water, move valuables out of the area
- Minute 5: Call an emergency plumber and your insurance helpline
What you do in these 5 minutes determines whether this is a R3,000 fix or a R30,000 disaster.
Minute 1: Kill the water
The main shutoff is usually one of:
- Under the kitchen sink (back wall)
- In the garage near the geyser
- In a service hatch near the front door
- At the water meter at the boundary — round concrete cover, lift it, turn the valve clockwise
Turn it 90° clockwise (or full clockwise on a wheel). If you've never located yours, find it RIGHT NOW even if there's no leak — and label it.
Minute 2: Kill the geyser
Switch the geyser breaker OFF at the DB board. Here's why:
A burst pipe drains the geyser. If the geyser empties while the element is still powered, the element burns out in 30 seconds — that adds R1,200–R2,200 to your repair bill on top of the original burst.
Minute 3: Drain the pressure
Even after the main is off, the pipes hold pressure that keeps water dripping. Open these in order:
- The lowest cold tap (garden tap or downstairs basin)
- All hot taps in the house
- Flush a toilet
Pressure should drop within 1–2 minutes and the leak should slow to a dribble.
Minute 4: Damage control
- Move electronics, books, furniture and rugs away from any water
- Lift saturated carpets if you can — they'll mould within 24 hours otherwise
- Towels and buckets under any active drips
- If water is in the ceiling and the ceiling is bulging — drill a small hole at the lowest sagging point with a bucket underneath. A controlled drain saves a R20,000 ceiling collapse.
- Photograph everything for insurance — wide shots and close-ups
Minute 5: Call
Emergency plumber
Look for one with the "Emergency available" badge. After-hours call-out is R900–R1,800. Ask:
- "What's your ETA?"
- "What's the call-out fee?"
- "What's the hourly rate after the first hour?"
- "Do you carry stock for copper / PEX / 22mm repairs?"
Get the answers on WhatsApp before they leave.
Your insurance helpline
Most household policies cover sudden burst-pipe damage. Call the 24-hour helpline now to:
- Open a claim reference
- Get authorisation if they have preferred plumbers
- Confirm what evidence they need (invoice with cause, photos, etc.)
What NOT to do
- Don't try to switch on lights or appliances in a water-affected room until everything's checked
- Don't tape over a major leak and walk away — pressure builds, the tape blows, you have a flooded house when you return
- Don't accept a verbal-only quote from the plumber — always written
- Don't throw away damaged items until the insurance assessor has seen them
What it will cost
- Plumber's emergency repair: R1,500–R3,500
- Ceiling repair if it collapsed: R8,000–R25,000
- Carpet replacement: R200–R600 per m²
- Electrical re-inspection if water reached the wiring: R1,500–R3,000
A burst pipe caught in 5 minutes typically costs R3,000–R5,000 total. The same pipe left for an hour while you were out costs R30,000+.
