DIY Disasters: How Sydney Homeowners Flood Their Own Homes

There is real satisfaction in solving problems around the house by yourself. A dripping tap, a slow draining sink or a worn showerhead might appear to be a simple weekend task. Online DIY videos even make many repairs look simple and easy to believe that a few tools are all you need.

The reality is however, very different. Plumbing installs in back of walls, ceilings and floors, and even a small mistake could lead to hidden leaks or a burst pipe. It may also lead to severe water damage. Repairing the damage can cost a lot more than it would have to cost to hire a professional plumber in the first place.

Some home and DIY plumbing repairs also pose safety concerns that could be a problem with insurance if they are not done to NSW standards.

This is not to say that there are no plumbing maintenance jobs that are safe to do yourself, the key is knowing which jobs to tackle and which to leave to a licensed plumber.

At Premium Sydney Plumbers, we’ve repaired many DIY jobs that went wrong. We’ve seen the same mistakes happen again and again. We hope these help you avoid costly repairs!

Why Does DIY Plumbing Go Wrong?

Most people believe that plumbing is all about tightening pipe fittings so they’re tight enough or replacing a pipe. The fact is that your plumbing is far more complex than it seems.

Many plumbing problems aren’t initially visible. A loose fitting inside a wall may leak for weeks and you might not notice the problem until stains appear.

Other common DIY plumbing failures are:

• Incorrect water pressure assessment
• Using the wrong pipe type or fittings
• Screwing fittings too tightly
• Following tutorials designed in a different country with different plumbing standards
• Using the wrong tool for the job
• Rushing a job and not shutting off the water

Not all plumbing systems are the same. Many older Sydney homes have a mix of copper, galvanised steel and plastic pipes. Joining the wrong materials can cause leaks or corrosion.

Gas fitting is very different from replacing a tap. It carries serious safety risks and should always be completed by a licensed professional.

Many homeowners accidentally cause more harm than good, with the cost of emergency call-out often much higher than the initial cost of having a qualified tradesperson.

Plumbing Jobs Sydney Homeowners Can Usually Do Safely

There are several common plumbing tasks which you can undertake yourself safely:

1. Replace a showerhead: Using the manufacturer’s instructions and a bit of thread tape is often quite straightforward.
2. Change a tap washer: Most taps start dripping because of worn-out washers, which can be replaced quite easily.
3. Unplug the cap to the shower drain: This is a normal way to maintain shower drains.
4. Clean kitchen drains: Flushing kitchen sinks regularly to get rid of food particles, grease, and soap helps prevent them from becoming clogged, and minimizes odors.
5. Check your water meter: To check for leaks you can do the water meter check to determine if any of the water is being used when all taps and appliances are turned off.

Use Tools Properly

When attempting repairs on your home’s pipes, most homeowners would probably grab the pipe wrench if something leaks or won’t connect properly. A pipe wrench is useful for many jobs. However, using too much force can crack fittings or damage threads. If you’re using force with something to try and move it or loosen it and it isn’t working then you’re likely making the problem worse.

Simple DIY maintenance can ensure efficient plumbing operations and can save you money in the long run. Stop if your project involves changing pipework. The same applies if you’re modifying water supply lines or working on hidden plumbing. These jobs should be left to a professional plumber.

Plumbing Jobs That Should Always Be Left to a Professional Plumber

Some plumbing jobs are safe to do yourself. Others are not. Many plumbing jobs in NSW must be completed by a licensed plumber. If you’re unsure, it is better to ask before you start.

There are serious health and safety issues associated with many plumbing jobs. They also require a licence in NSW. Unlicensed work may affect your home insurance. Only attempt jobs you know are safe.

When in doubt, consult an expert first, so you can avoid getting into a project that may end up costing more than expected.

Installing New Plumbing Fixtures

While it may sound simple to fit a new tap – there are plenty of videos that show how to install basic fixtures – they don’t show the problems such as leaks that hide behind walls or around pipes or damaged seals that can then cause ongoing issues. The job will also need to be carried out to the Australian plumbing codes.

Pipe Repairs Need Professional Expertise

There are some situations where pipes will inevitably leak or corrode, and will need repairing or replacing. A temporary patch job may suffice for the short term, but can fail in just a few days leading to water leaking through walls, floors and ceiling of your house.

Gas Work is Never a DIY Project

No amount of confidence or online research makes DIY gas fitting safe. Specialist knowledge, licensed work practices and testing equipment is required for gas systems. A minor error can lead to a potentially hazardous gas leak, endangering the safety of all who are in the home.

Unlike water leaks, gas leaks aren’t always obvious. Some emit a detectable smell, some may not be detectable but only with special equipment.

If you suspect a gas leak: Shut off the gas if safe to do so, do not use electrical switches and evacuate. Call the relevant emergency service afterwards. Please use the system again only after a licensed gas fitter has done an inspection. This is one area where there is no safe shortcut.

Hot Water Systems Require Specialist Knowledge

Every hot water system contains components that operate under pressure and high temperatures.

Do not attempt to replace a Hot Water Heater, repair a pressure relief valve or make water supply connections without the assistance of qualified professionals. An incorrectly installed hot water unit can create problems such as

• Inconsistent hot water
• Higher energy bills
• Water leaks
• Premature equipment failure
• Potential hazards from improper pressure control.

The Hidden Cost of DIY Mistakes

If the repair fails, it doesn’t take long before a leaking tap or a loose fitting turns into a large problem of water damage. Floors, walls, insulation and cabinetry may be affected long before the leak is visible.

DIY Saving	Possible Long-Term Cost
Saving on labour	Emergency plumbing repairs
Cheap replacement fitting	Burst pipes and flooding
Temporary repair	Major pipe repair
Ignoring a slow leak	Structural water damage and mould

The financial impact extends beyond repairing the plumbing itself.

Homeowners may also face:

• Flooring repairs,
• Cabinetry repairs,
• ceiling repairs,
• electrical inspections,
• mould remediation,
• increased water bills

If insurers determine that damage resulted from unlicensed plumbing work, claims may become far more complicated than expected.

Hence the most inexpensive repair may not be the most cost-effective. The early call of a professional often means that there will not be major urgent repairs later.

Warning Signs Your DIY Repair Has Failed

Many DIY repairs fail slowly, giving homeowners warning signs if they know what to look for.

After doing any plumbing work, look for these signs:

• Damp patches
• Peeling paint
• Musty smells
• Higher water bills
• Water pooling

If it looks dry, be sure to inspect the fittings that were repaired several times for the next 24 hours. Small leaks will usually only show up when there is an increased amount of water pressure in the system as a result of normal household use.

A quick response is likely to lead to an easier and cheaper repair.

Blocked Drains: Why DIY Isn’t Always Enough

Blocked drains are one of the most common plumbing problems Sydney homeowners face.

A lot of the time it might just be a cleaning issue, but if drainage issues keep recurring it is most likely not just a buildup of household trash.

These are typical reasons: Tree roots getting into underground pipes; foreign objects being flushed down the system; residues of soap accumulating over time; rust in old pipes.

Chemical drain cleaners can sometimes be of short-term use, but they do not treat the cause of the clog, and repeated use can even damage certain pipe materials.

Persistent drainage problems often require specialised equipment to identify exactly what’s happening inside the pipe. A camera inspection shows exactly what’s happening inside the pipe. It can locate cracks, collapsed sections, tree roots and blocked sewer drains.

Protecting Your Home Before Problems Start

Most plumbing issues don’t occur out of nowhere. Many times, minor problems start small and then grow into major repairable problems.

Some simple maintenance practices can minimise the chances of plumbing disasters and prolong the life of your home’s plumbing system.

Know Where Your Water Meter Is

All homeowners need to know where they have located their Water Meter and Main shut-off valve because of possible pipe burst causing an enormous water leak which would require turning the water off to prevent too much damage to the property.

It is also worthwhile checking your meter occasionally, even when you’re not using any water. If the meter is still ticking over, then you can be sure there is a hidden leak somewhere on your property that is losing water. Be sure to look out for any signs of changing water pressure.

Losing the pressure of your taps or showers suddenly is not normal and there is a cause for concern.

If you find that there are any water pressure changes in your home, this would usually mean hidden leaks, partially blocked pipes, failing valves, or developing plumbing problems; and this problem could escalate from a minor to a major repair.

Don’t Let the Hot Water System Go Cold

Many homeowners don’t consider servicing the hot water system until they run out of hot water. By regularly servicing the system, worn parts can be detected before they break down.

A plumber can conduct checks during maintenance to ensure that the pressure relief valve is in good working order and that there are no signs of leaks, as well as ensuring that the system is operating efficiently. Preventative servicing can also help to extend the life of your hot water heater and help to avoid any unwanted breakdowns.

Avoid Putting the Wrong Things Down Drains

Never put any of the wrong materials in drains at your home. Your plumbing system carries only waste water, not solid waste materials. This practice of disposing of any household material in the drain can result in a clog in a sewer drain or contribute to the development of food scraps that lead to buildup in your kitchen drains.

Schedule Annual Inspections

Older homes in Sydney are predisposed to plumbing problems even before visible evidence is present. Regular checks will help plumbing specialists check up on existing hardware, any corroded sections and any leaks before the condition evolves into an actual disaster. If needed pressure tests and video checks are conducted on wall-installed parts of plumbing with no disturbance to floors, the ground landscape or partitions. Preventive maintenance is almost always less expensive than emergency repairs.

Commonly Asked Questions

1. Will my DIY plumbing work invalidate my home insurance?

Sometimes, yes, it depends. Different house insurance policies have different terms and conditions, but damage caused by work carried out by unqualified people may not be protected under certain claims.

If you doubt whether a particular task ought to be carried out by licensed plumbing specialists, it’s wise to clarify first.

2. Is changing a tap simple?

Changing a washer for a tap is a minor task that many individuals are comfortable with, however, if you intend to change the entire tap fitting, it’s advisable to contact a licensed plumber for assistance.

3. How do I know if I have a leak behind the wall or under the floorboards?

Watch for water spots on the wall or ceiling, mould and mildew growing in the house, flaking paint on surfaces and an increase in the amount of water bills or your water meter running continuously, even though you’re not using any water.

4. When is camera inspection essential?

If the drains continue to have issues, like clogged toilets, slow drains, or sewage backup, it may be a good idea to use the camera to check the drain, particularly if you think that the issue is from tree roots, broken pipes or blockage in the main sewer lines.

5. Do the roots of trees harm underground pipes?

Certainly! The roots of a tree are drawn to moisture.

They will grow into any tiny cracks and joints in the pipeline seeking dampness.

Eventually, these roots may expand, narrowing the pipeline, stopping up its passage or breaking it altogether. This is an issue that will have to be handled by expert plumbers.

Conclusion

Routine plumbing maintenance is well within the ability of many homeowners.

Some plumbing jobs are safe to do yourself. Others aren’t. It is important to know the difference to save you thousands. If the task is more than just maintenance, then having a licensed plumber out before something becomes an issue is best.
