Plumbing Myths That Could Be Costing You Money

Plumbing Myths That Could Be Costing You Money

In today’s DIY-obsessed world, it’s easy to fall into the trap of plumbing “hacks” and tips that sound helpful — but actually create bigger problems in the long run. As plumbers, we see the aftermath of these myths every day across Sydney — from gurgling kitchen sinks in Liverpool to completely blocked drains in Hornsby caused by years of bad advice.

If you’re a homeowner, property manager, or landlord, these are the plumbing myths that could be quietly draining your wallet.

🔥 1. “Flushable wipes are safe — they say so on the packet”

This is hands down one of the most common myths we come across. Despite what the packaging says, most flushable wipes do not break down the way toilet paper does. They often cling to imperfections inside pipes and quickly attract other debris like hair and grease.

In high-density suburbs like Bankstown, we regularly clear out sewer lines packed with wipes that have compacted together into large, solid blockages. It’s an expensive and avoidable mess.

💡 Truth: Only human waste and toilet paper should be flushed. “Flushable” wipes should go in the bin — especially if your property has older pipes, clay lines, or tree roots nearby.

🐢 2. “A slow drain will eventually fix itself”

A lot of people ignore a drain that’s draining slowly — until it becomes a full blockage. A slow drain is your plumbing’s version of an early warning light. Whether it’s in the shower, kitchen, or toilet, it’s telling you there’s a partial blockage forming — and it’s only going to get worse.

In homes throughout Castle Hill and the Northern Beaches, tree roots and grease are common culprits for slow drains that eventually lead to flooding or overflow.

💡 Truth: If a drain is slow, don’t ignore it. That trickle can turn into a total blockage, often at the worst time — like during a Sunday family BBQ or right before an inspection.

🧽 3. “Hot water and detergent break down grease”

We hear this one a lot. While hot water may move grease down the pipe, it doesn’t make it disappear. Once the grease cools, it hardens and sticks to the inner lining of your pipes — especially in cooler months or properties with long horizontal pipe runs.

Over time, that grease builds up and traps everything else: food scraps, coffee grinds, pasta, and even hair. This forms a dense blockage, often deep in the line where plungers and store-bought solutions won’t work.

In kitchens across Liverpool and Bankstown, this is a major reason for frequent blocked sinks.

💡 Truth: Always dispose of grease in the bin. Wipe pans with paper towel before washing, and never rinse oil or fat down the sink — hot water or not.

🧪 4. “Chemical drain cleaners are an easy solution”

Those bright bottles at the supermarket may promise to fix your clogged sink, but they come at a cost — and not just to your wallet. Chemical drain cleaners:

• Eat away at older PVC or metal pipes

• Can damage rubber seals inside traps

• Kill helpful bacteria in septic systems

• Often don’t fully clear the blockage anyway

In older homes around Hornsby, where clay pipes are common, we’ve seen major pipe degradation and leaks caused by repeated chemical use.

💡 Truth: These products are best avoided. If plunging doesn’t work, it’s time to call a licensed plumber for a proper clean-out or jet blast.

🚿 5. “If there’s no leak, everything is fine”

Not all plumbing issues are visible. A silent toilet leak can waste hundreds of litres of water per day. A hidden pipe crack under a slab can go undetected for months — until water damage or mould appears. We’ve even seen blocked stormwater lines in Northern Beaches yards, where nothing seemed wrong until it rained heavily and the property flooded.

💡 Truth: Unexplained increases in water bills, musty smells, or wet grass on dry days are all warning signs. Regular inspections — especially before and after winter — can catch silent problems before they become disasters.

🧰 6. “All plumbers are the same — just get the cheapest one”

Choosing the cheapest option often ends in callbacks, rushed jobs, or bandaid fixes. A proper drain inspection, pipe repair or installation needs experience, proper tools, and the time to do it right. Otherwise, you’re just delaying (and inflating) the next repair bill.

We often get called out in places like Castle Hill, Liverpool, and Hornsby to fix problems that could’ve been avoided — or that were made worse — by dodgy tradies or short-sighted quick fixes.

💡 Truth: Invest in a licensed plumber who offers honest advice, clear pricing, and a warranty on their work. It saves you money (and headaches) in the long run.

🔎 Bonus Myth: “Plumbers just want to upsell you on unnecessary work”

At Get Unblocked, we hear this concern often — and we get it. Some operators do take advantage of non-technical homeowners. But here’s the reality: when we recommend pipe relining, a CCTV drain inspection, or replacing a cracked pipe, it’s because we’ve seen the damage that ignoring it causes.

We aim to educate and prevent, not upsell. If we can clear your drain with a jetter instead of digging up the yard, we’ll do that. If we see an issue coming, we’ll give you options — not pressure.
