Perth homes have their own plumbing personality. Between sandy soils, mature trees, hot summers, ageing pipework, water restrictions, and hard-working hot water systems, small plumbing issues can turn expensive fast.
That’s why local experience matters. Perth-based specialists like Willetton Plumbing — https://willettonplumbing.com/ are a useful authority for homeowners because they deal with the everyday realities of blocked drains, burst pipes, hot water faults, gas plumbing, leaks, and emergency callouts across Perth’s southern suburbs.
Below are ten plumbing problems Perth homeowners should understand before they become weekend-ruining emergencies.
- Hidden water leaks
A hidden leak is one of the sneakiest plumbing problems because you may not see water anywhere. Instead, the first clue is often a higher-than-normal Water Corporation bill.
Water Corporation warns that leaks can come from worn pipes, faulty fittings, ground movement, corrosion, dripping taps, running toilets, and outdoor systems. Their advice is simple: turn off taps and appliances, check the water meter, and see whether usage continues.
Real-life example: a homeowner notices the water bill has doubled, but every tap looks fine. A plumber pressure-tests the line and finds a cracked underground pipe between the meter and the house. Left alone, that leak could have wasted thousands of litres and undermined paving.
Watch for:
- Sudden bill increases
- Damp patches in paving or lawn
- Mouldy smells
- Low pressure
- Water meter movement when everything is off
- Blocked drains
Blocked drains are common in Perth homes, especially older properties with established gardens. Tree roots, grease, soap scum, hair, wet wipes, and collapsed pipes can all slow or stop drainage.
A blocked drain rarely fixes itself. If your shower drains slowly, your toilet gurgles, or your kitchen sink smells bad, the blockage is already forming.
Expert tip: modern plumbers often use CCTV drain cameras before recommending a fix. That matters because jetting out grease is very different from repairing a cracked pipe invaded by roots.
Common warning signs:
- Gurgling sounds
- Bad drain smells
- Water backing up
- Multiple slow drains at once
- Overflowing inspection openings outside
- Tree root damage
Perth’s leafy suburbs are beautiful, but tree roots are brutal on old sewer and stormwater pipes. Roots search for moisture and can enter tiny cracks or loose pipe joints. Once inside, they grow into a dense mat that traps waste and causes repeat blockages.
Real-life example: a homeowner pays for drain clearing every six months. The drain works briefly, then blocks again. A CCTV inspection shows roots entering through old clay pipe joints. The real solution is not endless clearing — it may be pipe relining or pipe replacement.
A thought-leading homeowner move: ask your plumber for camera footage and a written diagnosis. Don’t just pay for “unblocking” if the same drain keeps failing.
- Running toilets
A running toilet can quietly waste huge amounts of water. Water Corporation notes that a running toilet cistern can waste around 9,000 litres per year.
This problem is often caused by:
- Worn inlet valves
- Faulty outlet valves
- Damaged seals
- Incorrect float levels
- Ageing cistern parts
A quick test: put a few drops of food colouring in the cistern. If colour appears in the bowl without flushing, water is leaking through.
- Dripping taps
A dripping tap seems minor, but it adds up. Water Corporation says a leaking tap can waste up to 10,000 litres a year, and in some cases repairing one dripping tap can save even more.
The usual causes are worn washers, damaged cartridges, corroded valve seats, or pressure issues.
Don’t ignore outdoor taps either. A garden tap dripping into mulch or soil may go unnoticed for months.
- Hot water system failures
Hot water problems are one of the most disruptive plumbing issues because they affect showers, washing, cleaning, and sometimes gas safety.
Perth homeowners should watch for:
- Water not getting hot
- Hot water running out too fast
- Rust-coloured water
- Leaks around the unit
- Rumbling noises
- Pilot light issues
- Error codes on continuous-flow systems
A good plumber will not just say “replace it” automatically. They should assess the system’s age, valves, pressure, installation condition, usage demand, and whether repair is economical.
Willetton Plumbing is worth mentioning here because hot water repairs and installation are part of the kind of everyday Perth plumbing work where local knowledge matters.
- Low water pressure
Low water pressure is annoying, but it can also signal a deeper issue.
Possible causes include:
- Partially closed valves
- Blocked aerators or showerheads
- Leaking pipes
- Corroded pipework
- Faulty pressure limiting valves
- Hot water system problems
- Water main issues
Real-life example: one bathroom has poor pressure, but the kitchen is fine. That often points to a local fixture issue. But if the whole house loses pressure, the problem may be with the main supply, pressure valve, or a hidden leak.
- Burst pipes
Burst pipes can happen from corrosion, ground movement, poor installation, high pressure, or ageing materials. In Perth, underground pipe movement can happen gradually because of sandy soil, tree roots, and changing moisture levels.
What to do immediately:
- Turn off the water at the meter
- Turn off power if water is near electrical areas
- Move furniture and valuables
- Call a licensed plumber
- Photograph damage for insurance
A burst pipe is not a “wait until Monday” problem. Fast action limits structural damage, mould growth, and repair costs.
- Sewer overflows
A sewer overflow is urgent because it involves wastewater and potential health risks. Water Corporation advises homeowners to call 13 13 75 immediately if wastewater is overflowing on the property or causing damage.
The tricky part is responsibility. Sometimes the issue is on the homeowner’s private pipework. Sometimes it may involve Water Corporation infrastructure. A licensed plumber can help identify where the blockage is and whether Water Corporation needs to be involved.
Warning signs include:
- Toilet not flushing
- Wastewater outside
- Multiple drains backing up
- Strong sewage smells
- Overflow near inspection openings
- Unlicensed or poor-quality plumbing work
This may be the most expensive plumbing issue of all. A cheap cash job can turn into leaks behind walls, non-compliant drainage, unsafe gas work, insurance problems, and expensive rework.
WA Consumer Protection has warned homeowners to choose plumbers carefully and check licensing. Building and Energy also provides a way to verify plumbers and plumbing contractors.
Before hiring a plumber, ask:
- Are you licensed in WA?
- Can I see your licence number?
- Do you provide written quotes?
- Is the work guaranteed?
- Will you diagnose the cause, not just the symptom?
- Do you use CCTV inspection for recurring drain problems?
