Discover the most common plumbing myths in Perth and learn expert tips to save time, money, and stress.
Plumbing problems can be confusing, especially with so many myths floating around online or passed between neighbours. Believing the wrong advice can cause costly repairs, water waste, or even serious property damage.
In this article, we’ll bust the top five plumbing myths Perth homeowners should stop believing — and share what really works, straight from local plumbing experts.
1. You Can Pour Anything Down the Drain
Many people assume that sinks and drains can handle anything — from grease and coffee grounds to cleaning chemicals. In reality, these substances can:
- Cause stubborn blockages in your pipes
- Damage your plumbing system over time
- Contaminate Perth’s local water supply
Fact: Only flush wastewater, toilet paper, and biodegradable materials. Dispose of grease, oils, and food scraps properly using compost bins or your rubbish bin instead.
Pro Tip: Regular blocked drain clearing services help prevent future clogs and keep your plumbing flowing freely.
2. Dripping Taps Are Harmless

A slow drip might not seem urgent, but over time it can:
- Waste thousands of litres of water each year
- Increase your water bill
- Lead to corrosion in fittings and fixtures
Fact: Even a small leak can cause big problems if ignored. Fix drips quickly to prevent damage and reduce waste.
Pro Tip: A professional leak detection service from a licensed Perth plumber can find and repair hidden leaks before they escalate.
3. DIY Repairs Are Always Cheaper
DIY tutorials make plumbing look simple — until something goes wrong. Incorrect repairs can:
- Cause pipe bursts, leaks, or water damage
- Shorten the lifespan of hot water systems and appliances
- Void warranties on plumbing fixtures or gas fittings
Fact: DIY plumbing may seem cheaper, but a single mistake can cost thousands in repairs.
Pro Tip: Calling a qualified emergency plumber in Perth ensures your repair is safe, compliant, and long-lasting.
4. All Water Heaters Are the Same
Not all hot water systems deliver the same performance. The right choice affects comfort, energy efficiency, and running costs.
Here’s the truth:
- Tankless (instant) systems provide efficient, on-demand hot water
- Traditional storage heaters are reliable and affordable
- Perth’s water quality and climate influence system performance
Fact: Choosing the right system for your household can save money and extend your heater’s lifespan.
Pro Tip: Professional hot water system installation and maintenance services ensure your system runs safely and efficiently all year round.
5. Low Water Pressure Is Normal in Older Homes

Many older homes in Fremantle, Mount Lawley, and other Perth suburbs experience low water pressure — but that doesn’t mean it’s normal. Persistent low pressure could signal:
- Blocked or corroded pipes
- Faulty fixtures or valves
- Issues with your property’s main water line
Fact: Low water pressure is often a sign of an underlying issue, not just age.
Pro Tip: Timely general plumbing services can restore proper flow and prevent ongoing pressure problems.
