Plumbing problems have a way of showing up at the worst possible times. One minute, everything’s fine. The next, there’s water pooling under the sink, the toilet won’t flush, or you’re ankle-deep in a slow-draining shower. Some issues are minor and easy to fix, while others can quickly spiral into costly disasters if ignored. The good news? A little knowledge can go a long way in preventing major headaches. Here are ten common plumbing issues, what causes them, and what you can do about them.
1. Dripping Taps – The Sound of Wasted Money
A constant drip isn’t just annoying—it’s also a huge waste of water. Even a slow-dripping tap can waste litres of water every day, driving up your water bill. In most cases, the culprit is a worn-out washer, O-ring, or cartridge inside the tap. Replacing these small parts is usually an easy DIY fix, but if the problem persists, it might be a sign of high water pressure or corrosion inside the tap, so get in touch with one of the best plumbers Adelaide has to offer and they’ll fix the problem for you.
2. Slow or Clogged Drains – A Sign of Trouble
A sluggish drain might seem like a minor inconvenience, but it’s usually a warning that something is building up inside the pipes. In the kitchen, grease and food particles are often the problem. In the bathroom, hair and soap scum are the usual culprits. Regularly using a drain guard can help prevent clogs, but if the water is taking ages to drain, try using a plunger or a drain snake. Avoid chemical drain cleaners, as they can damage pipes over time.
3. Running Toilets – A Silent Water Waster
A running toilet can waste hundreds of litres of water a day without you even realising it. If you hear constant running water long after flushing, the most likely cause is a faulty flapper valve, which controls the flow of water from the tank to the bowl. Replacing it is cheap and easy, but if the problem continues, it could be an issue with the fill valve or float. Ignoring a running toilet won’t just cost you on your water bill—it can also put extra strain on your plumbing system.
4. Low Water Pressure – More Than Just a Weak Shower
If your taps or showerhead seem to be producing a weak trickle instead of a steady stream, you’re dealing with low water pressure. In older homes, this is often caused by a buildup of sediment or mineral deposits in the pipes or fixtures. Try cleaning the aerators on your taps and showerheads with vinegar to remove any blockages. If the issue is affecting multiple taps, it could be a sign of a hidden leak or a problem with the main water supply.
5. Leaky Pipes – A Problem That Won’t Fix Itself
Leaks can start small, but they rarely stay that way. Whether it’s a visible leak under the sink or a hidden one behind the walls, even a tiny drip can lead to serious water damage and mould growth over time. If you spot damp patches, water stains, or a musty smell, it’s time to investigate. Tightening connections or replacing worn-out seals might help, but persistent leaks should always be checked by a professional to avoid bigger problems down the track.
6. Blocked Toilets – A Common (and Avoidable) Headache
A toilet that won’t flush properly is usually caused by a blockage in the drain. Most of the time, a plunger will do the trick. If that doesn’t work, a drain snake can help break up tougher clogs. The best way to avoid a blocked toilet? Be mindful of what gets flushed. Only toilet paper should go down—no wipes, cotton buds, or other non-flushable items. Even products labelled ‘flushable’ can cause problems over time.
7. Water Heater Issues – No One Likes a Cold Shower
There’s nothing worse than stepping into the shower and being blasted with icy water. If your water heater isn’t producing enough hot water (or any at all), the problem could be a faulty thermostat, a buildup of sediment in the tank, or a broken heating element. Regularly flushing your water heater can help extend its lifespan by preventing sediment buildup. If the issue persists, it’s best to get a plumber to take a look before it fails completely.
8. Burst Pipes – An Emergency You Don’t Want to Ignore
A burst pipe is one of the most serious plumbing emergencies you can face. It can cause major flooding and damage to your home in minutes. Pipes often burst due to freezing temperatures, corrosion, or excessive water pressure. If a pipe bursts, immediately shut off the main water supply and call a plumber. Insulating exposed pipes and checking for signs of wear and tear can help prevent this from happening in the first place.
9. Sewer Line Backups – A Messy, Smelly Problem
If multiple drains in your home are backing up, or you notice a foul smell coming from your drains, you could be dealing with a sewer line blockage. This is often caused by tree roots growing into the pipes or a buildup of grease and debris. Unlike a simple clogged drain, this isn’t something you can fix with a plunger. A plumber will need to inspect the line and clear the blockage to prevent sewage from backing up into your home.
10. Noisy Pipes – More Than Just an Annoyance
Banging, rattling, or whistling pipes might not seem like a big deal, but they can indicate underlying plumbing issues. Loose pipes can vibrate when water flows through them, while high water pressure can cause pipes to shake and make loud banging noises (known as water hammer). Installing a pressure regulator or securing loose pipes can help stop the noise and prevent potential damage to your plumbing system.
Stay on Top of Plumbing Problems Before They Get Worse
Plumbing issues might not always seem urgent, but even small problems can escalate quickly if left untreated. Regular maintenance, being mindful of what goes down your drains, and fixing minor leaks early can help prevent major repairs down the line. Some problems are easy to handle yourself, while others require a professional touch. Either way, staying proactive can save you money, water, and a whole lot of hassle.
