The Ultimate Plumbing Checklist for Australian Households This Summer


The Australian summer is synonymous with BBQs, beach visits and long afternoons in the backyard but with all that comes hot days. The more people shower, the more they cook and do the washing, the harder your plumbing is working. When that happens, small problems can turn into bigger ones quite quickly.


Plumbing can be tricky but giving things a quick look now can help you avoid problems later. To make it easy for you, we have put together a simple summer plumbing checklist you can use before the heat sets in.


Why Summer Plumbing Maintenance Matters in Australia

Before we get into the checklist, it helps to understand why summer plumbing maintenance is so important. Aside from the things we mentioned earlier, we also get sudden storms that can test your gutters, stormwater drains and roof plumbing in one hit.


A bit of household maintenance now can:

  • Decrease the risk of flooding in heavy rain
  • Keep your water bills under control
  • Extend the life of your hot water system and pipework
  • Prevent smelly or blocked drains when the house is full of people



Indoor Plumbing Checks Every Homeowner Should Do


- Look for Leaking Taps and Fixtures

Inspect taps and leaking fixtures by going room to room and testing each one. Turn the tap on and off fully, listen for any drips once it is closed and check for water collecting around the base of the tap or mixer. Even a slow drip adds up over summer. Aside from being annoying, they are also a sign that part of your residential plumbing needs attention.


- Check Water Pressure and Flow Rates

Next, pay attention to how your water behaves. In different rooms, turn taps and showers on. If you see some water pressure issues or one part of the house is always weak, it is worth asking a plumber to check it before the summer rush makes it worse.


- Test Your Hot Water System Before Peak Usage

Hot water is about comfort and safety, so it is worth giving your system a quick look now and then. Check that your hot water reaches all taps, heats up in good time and is not making strange noises or showing obvious damage. You do not need to pull it apart to see how it is performing. You just have to pay attention to how it works day to day.


- Hot water system safety checks

Make sure nothing around the unit looks damaged, there is no constant trickle from the relief line and no water pooling on the ground nearby. If you have young kids or elderly family members, water that is too hot at the tap can be risky, so the temperature needs to be set correctly. If you are not sure how to check your hot water system safely, it is best to get a licensed plumber to do it for you.


Signs your hot water system needs service


  • Hot water keeps changing temperature 


  • Rusty or coloured water from the hot tap 


  • Popping or rumbling sounds from the tank 


  • System is 8–10 years old with no service



Plumbing Maintenance for your Kitchen

Check the Sink

Check for sink leaks and moisture by looking inside the cupboard under your kitchen sink for damp spots, swollen or soft timber, stains or any signs of corrosion around the hoses and joints. Leaks here are usually slow and easy to miss. However, they can cause a lot of damage to your cabinets and flooring if they are left too long.


Run a Drain Health Check

While using the sink, pay attention to how well it drains. Have a go at answering the following.


  • Does the water go down freely


  • Does it sit and slowly swirl away


  • Do you notice a smell after using the sink or dishwasher


Early signs of blocked drains

In the kitchen, early signs of a blockage include:


  • Water that is backing up in one side of a double sink


  • Gurgling noises when the dishwasher is emptying


  • Air bubbles rise when you tip out a pot or bucket



When to call a plumber

There is only so much you should do yourself. If plunging does not clear the drain or more than one fixture is slow, call general plumbing services. If you see water coming out where it should not, like at the base of cabinets, get a professional in straight away.



Plumbing Checklist for Bathroom and Laundry


Inspect Showers, Toilets and Pipes for Wear

In the bathroom, keep an eye out for cracked or missing silicone around the shower and bath. Watch for water that drains slowly, toilets that keep running and any exposed pipes with rust or green staining. Fortunately, a simple water pipe maintenance can already go a long way.


Check Washing Machine Hoses and Valves

In the laundry, it is worth checking behind your washing machine now and then to make sure the hoses are not cracked, kinked or bulging, the taps and fittings are not slightly leaking and there are no water stains on the wall or floor. 



Outdoor Plumbing and Summer Preparation


Test Outdoor Taps and Garden Hoses

Walk around the yard and make sure each garden tap turns on and off properly. Also check that there are no leaks around the handle or spindle. You should also look at the hose connections for any constant dripping. Be sure to check the hose itself for splits, cracks or bulges too.


Inspect Stormwater Drains Before Summer Storms

Before the worst of the summer storms arrive, clear leaves and rubbish from drains, make sure downpipes are secure and unbroken. Remember to also take note of any low spots in the yard where water tends to collect.


This is really just the practical side of a checklist for summer roof plumbing middle class homes. If you have trees nearby, even a small amount of leaves and debris can block a stormwater line. If you keep getting flooding or pooling in the same spots, it is worth asking a plumber to camera check your stormwater system so you know what is going on underground.


Check Irrigation Systems for Leaks

If you use sprinklers, drippers or any irrigation, run each zone and watch how the sprinklers work.


How heat affects outdoor plumbing

Heat is hard on outdoor plumbing. Aside from that, plastic fittings can become brittle and crack and rubber washers dry out and start to leak. Moreover, exposed pipes expand and contract every day in the sun. Over time, all of this movement and UV exposure can cause your fittings to fail.


When to Call a Professional Plumber

You can handle a lot of basic checks yourself but there are times when calling in general plumbing services is the safest choice.


Issues That Need Immediate Attention

Call a plumber straight away if you notice any of the following:


  • A heavy leak from a pipe, ceiling or wall 


  • A strong odour of sewage in the house or yard 


  • Drains are gurgling or overflowing 


  • No hot water or the system keeps tripping the power 


  • New water discolorations on ceilings or walls after rain

What Causes Pipes to Leak in Older Newcastle Homes? Older homes around Newcastle have a charm that is hard to copy. But while the character of an older home is easy to see, the plumbing behind the walls can be much harder to notice. Homes that were built decades ago often have plumbing that has started to wear down over time, and small leaks can start in areas you wouldn’t usually check. Knowing what to watch for can help you avoid being caught off guard by a leak or burst pipe. Here’s our list of things you should know about your plumbing. Old Pipes Can Start to Corrode Pipe corrosion is one of the main reasons older homes develop leaking pipes. Over time, minerals in your water and other substances wear down the metal inside the pipe. Once the pipe wall becomes weak, leaks can appear around joints and fittings. Corrosion can also leave sediment inside the pipe. This can slow the water flow and increase the risk of a clogged pipe. Since these issues usually build up slowly, they are more common in old plumbing systems. How to Minimise Damage: Unfortunately, once pipe corrosion starts, it can continue to get worse over time. As the pipe weakens, more areas become exposed to damage. What you can do is call a plumber ASAP so the affected pipe can be checked. Even Modern Pipes Will Wear Down From Years of Use Whilst pipes are intended to last for years, none of them will last forever. Modern plumbing techniques aren’t immune to the strain your pipes will go through from years of constant use. Unlike metal pipes, plastic or PVC pipework will not rust. Instead, plastic pipework can become brittle. As it becomes less flexible, it can crack more easily near fittings. Abrupt changes in temperature can also slowly add stress to your pipes. Hot water can make the pipe expand a little then it tightens again as it cools. After years of this movement, pipework can become stressed and fail. How to Minimise Damage: The good news is that you won’t have to worry about damages for quite a few years if you’re caring for your pipes adequately. At some point in the future, replacing the damaged pipe will be the best way to stop any leaks. This usually happens when the pipe has become too worn to hold another patch. Tree Roots Can Get Into Your Plumbing Do you have gorgeous, large trees around your 1930’s home? They may give nice shade, but their roots can spread underground in search of moisture. Specifically, stormwater and sewer pipes are common places for roots to get in. This is especially true when there is already a small crack or loose joint. Once they grow inside, they can put pressure on the pipe and cause leaks. Over time, your pipes can become badly damaged or even collapse, leading to burst pipes Newcastle homeowners may need to repair urgently. How to Minimise Damage: Prevention is the best way to stop roots from damaging your plumbing system. You should always plant new trees away from main water or sewer lines to help prevent any issues for future-you. In addition, aim to avoid species with aggressive roots - especially near older plumbing systems. If you already have mature trees near old plumbing lines, it is important to have them regularly checked by professionals. If roots have already moved into the pipe, call Jet Blaster Man to have them properly treated. Ground Movement Can Affect Your Pipes Over time, it is normal for homes to settle further into the ground. A little settling is normal, but too much movement caused by the weather and soil changes can strain the pipes. Wet soil expands, and then shrinks again as it dries. This back-and-forth movement can shift the foundation slightly and impact your pipes, and it’s a common plumbing issue in older homes when the pipework is already worn. How to Minimise Damage: If you’ve had a lot of storms recently and think ground movement is affecting your plumbing, a professional inspection can help put your mind at ease. With advanced leak detection methods, the affected section can be found more accurately. As such, plumbers can find hidden water leaks without digging up more than needed. There Are Downfalls To High Water Pressure High water pressure feels great when you are in the shower or trying to fill the tub fast. But if the pressure stays too high all the time, it can slowly damage the plumbing system. Many pipes are only built to work within a safe pressure range, and when water moves through the pipes too fast for too long, it can wear them down more quickly. If the problem is ignored, high pressure can even lead to a burst pipe and a much bigger repair. How to Minimise Damage: You can use a pressure gauge to see if your water pressure is too high. If you are not sure how to test it, a plumber can do this safely. Additionally, you can have a pressure regulator installed to protect the plumbing from extra stress. Things to Watch Out For Until the plumbing in your home is inspected properly, the actual source of the leak may stay hidden. If the following signs keep getting worse, we recommend giving Jet Blaster Man a call so we can send a professional plumber out. You should keep an eye out for: Unusual water marks and stains on walls A musty smell A higher water bill than normal Reduced flow when you turn on taps/showers Presence of mould in hidden corners Mildew in rarely checked spots Water sounds when no taps are running Need a Plumber for Leaking Pipes in Newcastle?
