Spring is the best time for Sydney homeowners to inspect their plumbing before summer storms, higher water use and holiday entertaining place extra demand on the system.
This practical spring plumbing checklist covers stormwater drains, blocked drains, hidden leaks, hot water systems, water pressure, flexible hoses and water filters. Identifying problems early can help prevent water damage, plumbing emergencies and expensive repairs.
Quick spring plumbing checklist
Before summer, check your:
- Stormwater drains, grates, gutters and downpipes
- Kitchen, bathroom and laundry drains
- Sinks, toilets and exposed pipework
- Outdoor taps, hoses and irrigation connections
- Water meter and areas around the property for hidden leaks
- Hot water system
- Water pressure
- Flexible braided hoses
- Water filtration cartridges
If you notice a leak, recurring blockage, unusual plumbing noise or change in water pressure, arrange an inspection with a licensed plumber.
1. Clear leaves and debris from stormwater drains
Sydney’s spring rain can quickly expose blocked stormwater drainage. Leaves, soil, mulch and garden debris may collect around outdoor drains, stormwater grates and drainage pits. If water cannot flow away efficiently, it may pool around the property, overflow into garages or enter low-lying areas.
Clear visible debris from:
- Outdoor stormwater grates
- Drainage channels
- Driveway drains
- Balcony and courtyard drains
- Gutters and downpipes
- Stormwater pits
After clearing the surface, pour a small amount of water toward the drain. The water should flow away freely without pooling. Slow drainage may indicate a deeper stormwater blockage, damaged pipe or tree-root intrusion.
Do not remove heavy drain covers or enter stormwater pits yourself. If a drain remains blocked, contact a professional plumber for a safe inspection and stormwater drain cleaning.
2. Pay attention to slow or gurgling drains
A drain does not need to be completely blocked to indicate a developing plumbing problem.
Look for:
- Water draining more slowly than usual
- Gurgling toilets, sinks or floor drains
- Unpleasant smells from drains
- Water rising in another fixture when a toilet is flushed
- Repeated blockages in the same drain
- Water backing up during showers or laundry use
Common causes include grease, soap, hair, foreign objects, tree roots, damaged pipes and obstructions further along the drainage system.
A chemical drain cleaner may provide temporary relief but can damage some pipework and will not resolve structural problems. If a blockage keeps returning, a plumber can use a CCTV drain camera to identify the cause and recommend the correct repair.
3. Inspect sinks, toilets and visible pipework for leaks
Small plumbing leaks often remain hidden inside cupboards or behind fixtures. Over time, they can cause mould, swollen cabinetry, damaged flooring and unpleasant odours.
Check underneath kitchen, bathroom and laundry sinks for:
- Dampness or standing water
- Water stains
- Swollen or discoloured cabinetry
- Mould or musty smells
- Corrosion around pipes and fittings
- Loose connections
Also inspect around the base of each toilet. Movement, moisture, staining or discolouration may indicate a failed toilet seal or another leak.
If you find moisture, dry the area and check it again later. Persistent dampness should be assessed by a licensed plumber before it causes further damage.
4. Test outdoor taps, hoses and irrigation connections
Outdoor plumbing can deteriorate without being noticed, particularly when garden taps are not used regularly during winter.
Turn each outdoor tap on and check for:
- Leaks around the handle or connection
- Dripping after the tap is turned off
- Reduced water pressure
- Corroded fittings
- Loose or damaged pipework
Inspect garden hoses, hose reels, irrigation valves and connections as well. A slow outdoor leak can waste water and create damp areas around walls, paving, retaining structures and garden beds.
5. Check for signs of a hidden water leak
Some leaks occur inside walls, beneath floors or underground and may not be immediately visible.
Warning signs of a concealed water leak include:
- An unexplained increase in water bills
- The sound of running water when all fixtures are off
- Damp patches on walls, ceilings or floors
- Peeling paint or swollen skirting boards
- Mould that repeatedly returns
- Unusually wet or green areas in the garden
- Cracks, sinking soil or unexplained water pooling
- A water meter that continues moving when no water is being used
To perform a basic water-meter check, turn off all taps and water-using appliances, wait several minutes and observe the meter. If it continues recording water use, contact a plumber for professional leak detection.
Early leak detection can help reduce water waste and limit damage to walls, flooring, cabinetry and landscaping.
6. Inspect your hot water system
A hot water system should be checked regularly, particularly if it is older or approaching the end of its expected service life.
Look for:
- Rust or corrosion
- Water pooling around the unit
- Leaking valves or connections
- Banging, popping or rumbling sounds
- Hot water running out sooner than usual
- Fluctuating water temperature
- Discoloured hot water
- Higher-than-usual energy costs
Do not remove covers, adjust internal components or attempt to repair a gas, electric or heat-pump hot water system yourself. These systems may involve electricity, gas, pressure and very hot water.
A qualified plumber can inspect the system, identify safety concerns and advise whether repair, servicing or replacement is appropriate.
7. Check your home’s water pressure
Water pressure that is too low can make showers and taps difficult to use. Excessive pressure can place unnecessary strain on pipes, valves, appliances, flexible hoses and fixtures.
Signs of a water-pressure problem include:
- Weak flow from several fixtures
- Banging pipes
- Taps that are difficult to control
- Frequent leaks from hoses or fittings
- Water spraying forcefully from taps
- Pressure that changes significantly when another fixture is used
Do not judge pressure from one tap alone. If pressure has changed throughout the home, a plumber can test it accurately and investigate possible causes such as a faulty pressure-reducing valve, blocked pipework or a problem with the water supply.
8. Inspect flexible hoses
Flexible braided hoses are commonly installed beneath sinks, basins and toilets. If one bursts, it can release a large amount of water in a short time.
Check each hose for:
- Rust spots
- Fraying or bulging
- Kinks
- Moisture around the connections
- Signs of deterioration
Do not store cleaning products tightly against the hoses, as they can place pressure on the fittings or conceal a developing leak. Replace any hose that appears damaged or deteriorated.
9. Replace overdue water-filter cartridges
If your home has an under-sink or whole-house water filtration system, check when the cartridges were last replaced.
Overdue filters may:
- Reduce water flow
- Affect taste or odour
- Become less effective at filtering contaminants
- Place unnecessary pressure on the system
Replacement intervals depend on the filter type, water quality, household size and water usage. Follow the manufacturer’s instructions or arrange a water-filtration service if you are unsure which cartridge is required.
10. Resolve small plumbing problems before summer
Spring is an ideal time to complete plumbing maintenance before summer storms, school holidays and increased entertaining place extra pressure on your home’s plumbing.
Do not ignore:
- A dripping tap
- A slow or gurgling drain
- A leaking toilet
- Low or excessive water pressure
- A noisy hot water system
- A moving water meter
- Dampness beneath a sink
- A blocked stormwater drain
Addressing these warning signs early may help prevent emergency plumbing call-outs, water damage and higher repair costs.Need help checking your home’s plumbing?
When should you call a plumber?
Contact a licensed plumber if:

What should I check in my plumbing before summer?
Check stormwater drains, gutters, downpipes, sinks, toilets, outdoor taps, flexible hoses, hot water systems, water pressure and water filters. Also check your water meter for signs of a concealed leak.
How do I know if my stormwater drain is blocked?
Water that pools around a grate, drains slowly, overflows during rain or produces unpleasant smells may indicate a blocked stormwater drain. Leaves and debris should be cleared from the surface, but persistent problems require professional inspection.
Why is my drain gurgling?
Gurgling may indicate restricted airflow, a partial blockage, a blocked vent or a problem further along the drainage system. If the sound is recurring or accompanied by slow drainage, arrange a drain inspection.
How can I check for a hidden water leak?
Turn off all taps and water-using appliances, then observe your water meter. If it continues moving, your property may have a leak. Damp patches, mould, unexplained water bills and wet garden areas are also warning signs.
How often should flexible hoses be replaced?
Flexible hoses should be inspected regularly and replaced if they show rust, corrosion, bulging, fraying, cracking or leaking. A plumber can advise on replacement based on the hose’s condition and age.
When should a hot water system be serviced?
Hot water systems should be inspected when they show signs of leaking, corrosion, unusual noises, inconsistent temperature or reduced performance. Older systems may also benefit from a professional assessment before failure occurs.
