Pre-Holiday Plumbing Checklist: 7 Checks Before You Go Away

Getting ready for a holiday usually means packing bags, sorting travel plans and making sure the house is locked up. Plumbing rarely makes the list, but a small problem can cause plenty of damage when nobody is home to notice it.

Whether you’re leaving for a long weekend or heading away for several weeks, a little preparation can help you leave with fewer worries. This pre-holiday plumbing checklist is a practical place to start.

Why Your Plumbing Needs Attention Before You Go Away

An unattended home gives a plumbing fault more time to cause damage. A leak you would normally hear or notice underfoot can continue while nobody is there to act.

For example, imagine a laundry hose failing the morning after you leave for a week. Without someone checking the property, water could spread well beyond the laundry before it is discovered. Completing your plumbing checks before holidays gives you time to address warning signs and helps prevent water damage while away.

Find and Test Your Main Water Stop Valve

Locate your property’s main water stop valve and check that it operates before you need it urgently. In many mains-connected homes, it is near the water meter, but shared supplies and acreage properties can have different arrangements.

Gently close the valve, then briefly open a cold tap to check that the flow stops after residual water drains. Reopen the valve slowly when finished. If it is seized, leaking or fails to stop the supply, have a plumber assess it rather than forcing it.

Whether you should turn off water before holidays depends on what needs a continuous supply. Check requirements for irrigation, livestock troughs, fire protection and water-dependent equipment first, including your hot water unit. Where a full shutdown is unsuitable, ask about isolating individual fixtures or appliances.

Check Flexible Hoses and Visible Pipework

Look under sinks, behind toilets and around the laundry for deteriorating water connections. A burst flexi hose can release water into cupboards and adjoining rooms, so damaged hoses deserve attention before the house is left empty.

Use a torch to check accessible hoses and fittings for these warning signs:

• Rust, frayed braiding or bulging along flexible hoses.
• Sharp bends, twisting or connections under tension.
• Moisture, staining or swollen cabinetry around fittings.
• Drips or corrosion on exposed pipework.

A hose can still have problems without obvious external damage. Arrange professional assessment of anything questionable and turn off washing machine and dishwasher supply taps where accessible and suitable for the appliance. Avoid pulling heavy appliances out simply to reach a hidden connection.

Do a Quick Water Meter Leak Test

A water meter leak test can reveal unexplained water use when everything appears switched off. Do this while the mains supply is on, before your final departure shutdown.

Follow these steps when nobody needs water:

1. Turn off all taps and pause water-using appliances, irrigation and automatic top-up systems.
2. Photograph or write down the full meter reading, including the smaller digits or dials.
3. Leave the meter valve open and avoid using water for at least one hour, including flushing toilets.
4. Compare the reading with your starting figure.

Movement or an increased reading suggests water is still passing through the meter. Check for overlooked automatic use, then arrange a plumber if the change remains unexplained. The test does not locate the fault or rule out every intermittent leak.

Set Your Hot Water System for Time Away

Check your unit’s manual before changing its settings or isolating the water supply. Hot water system holiday mode is available on some models, but there is no single shutdown procedure suitable for every electric, gas, solar or heat pump unit.

If a holiday setting is provided, follow the manufacturer’s instructions for activating it and restarting normal operation. Avoid simply lowering a storage thermostat or switching off controls without checking the manual. Some systems need power for protective functions even when nobody is using hot water.

If you are unsure how your hot water system should be left, ask a licensed plumber before departure. Have leaks, unusual noises or unreliable heating checked while there is still time to arrange repairs.

Clear Gutters, Downpipes and Stormwater Drains Before Storm Season

Clear drainage paths before leaving, particularly when your trip overlaps the Gold Coast storm season. Turning off the mains supply cannot stop rainwater entering through overflowing gutters or backing up around the house.

Remove accessible leaves and debris from ground-level drain grates and arrange gutter and downpipe cleaning where needed. Leave roof access and difficult ladder work to someone suitably equipped. Keeping gutters and downpipes clear allows rainwater to drain away more freely.

Consider how the property performed during the last heavy rain. Overflowing gutters, pooling near doorways or water lingering over stormwater drains warrant investigation. Clearing a grate will not resolve a blockage further along the pipe, so arrange assessment if the problem keeps returning.

Fix Dripping Taps and Running Toilets

Repair ongoing drips and running cisterns before departure, even if they seem minor. They waste water whenever the supply remains on and can also explain movement during your meter test. Listen for toilets refilling between flushes and check whether water continues trickling into the bowl after the cistern has filled. Inspect indoor and outdoor taps after use, including garden taps connected to hoses.

Schedule plumbing maintenance early enough to check the repair afterwards. Closing a tap harder each time is not a lasting solution and can make worn fittings more difficult to operate.

Extra Checks for Acreage Properties: Tanks, Pumps, Septic and Irrigation

Acreage properties need a shutdown plan that accounts for each separate water source and system. Closing a mains valve may leave tank-fed plumbing pressurised, while switching off all power could interrupt essential wastewater treatment.

Walk through the property and check the following:



• Rainwater tanks: Look for leaking outlets and clear accessible inlet screens and overflow openings.
• Pressure pumps: Investigate unexplained cycling when no water is being used. Confirm shutdown instructions with the pump supplier or plumber.
• Septic and treatment systems: Check for alarms, unusual odours or wet ground around disposal areas. Ask your service technician about holiday operation and keep powered treatment equipment running as instructed.
• Irrigation: Run a cycle to spot broken fittings, leaking valves or water spraying towards buildings. Adjust scheduling for your absence without interrupting essential animal water supplies.

Conventional septic tanks and powered treatment plants operate differently. Follow the instructions for your actual installation rather than applying a general holiday shutdown rule.

Book a Plumbing Check Before You Head Away

The most useful pre-holiday plumbing checklist ends with action: repair suspect fittings, confirm which supplies can be isolated and leave clear instructions for whoever checks the property. Start early enough to allow for diagnosis, parts and a follow-up check.
