    There is no worse end to a holiday than opening your front door to the sound of running water. A few minutes before you leave can save you a flooded, ruined home. Here is the checklist.

    1. Close the main stopcock

    The single most effective step. With the main water off, a burst pipe or failed flexi-hose cannot flood an empty house for days. Know where your stopcock is and turn it off. (If a backup tank or irrigation must keep running, isolate just the house plumbing.)

    2. Switch off the geyser

    For trips of a few days or more, switch the geyser off at the DB board — it saves power and removes the risk of a fault running unattended. Flip it back on a couple of hours before you return, or schedule it with a GeyserWise controller.

    3. Check flexi-hoses and connections

    Glance under basins and behind the toilet for any drips, rust or bulging flexi-hoses before you go. A weeping connection now is a flood later.

    4. Protect against surges

    Load-shedding surges damage appliances in empty homes — make sure surge protection is in place and unplug sensitive electronics.

    5. Keep security powered

    Make sure gate and alarm backup batteries are healthy so security survives load-shedding while you are away.

    6. Leave an emergency contact

    Make sure a neighbour or family member can access the property — and has our number. Save it before you travel. Safe travels.

    Frequently Asked Questions

    Yes — closing the main stopcock before a long trip is the single best way to prevent a burst pipe or failed flexi-hose from flooding an empty house for days. If you have a backup water tank or irrigation that must keep running, isolate only the house plumbing instead.
