How do I maintain my water heater unit?


A hot water unit or a hot water system has now become a necessity especially during the winter season. With different types of hot water systems like gas and electric, solar-powered and heat pumps, its care and maintenance would depend on the type as well as the size of the water heater unit that you own. Since hot water systems are an investment, it is best to take care of them to make sure that they are in proper working condition at all times.

As experienced master plumbers and gas fitters, we make sure to know all the ins and the outs of the different types of hot water systems so that we can help our clients with their hot water system needs.  From hot water installations to unit replacement, we have 24/7 customer support ready to help our clients with any hot water system and plumbing concerns.

If you have a water heater tank for gas, electric, solar-powered hot water systems or heat pumps, it’s best to drain the tank every couple of months so that you can remove the debris and the small sediments that might have accumulated at the bottom of the tank. Cleaning the tanks a couple of times a year is necessary to keep the unit in perfect working condition and avoid sediment accumulation which can cause blocked pipes. To do this, drain about a quarter of the tank, open the pressure relief valve a little, hook up a hose and then allow water to run down the sediments. For tankless hot water systems, make sure to clean the exterior as well by running it with water to remove the debris that might have settled on the unit which when left unattended can solidify and affect the quality of the material of your unit.

The pressure valve in a hot water unit is designed as a safety precaution if a tank over pressurises. Checking the temperature and relief valve and making sure that it works properly is always a good thing. Occasionally turning the knob can help prevent the knob from freezing. And if it is too loose, make sure to tighten it a little to keep the pressure intact.

When you are about the leave town for months or even a couple of weeks and no one would be left at home, make sure to turn off your hot water systems not only to save on gas or electricity but also to put your unit at rest and prolong its life. Turning off your entire plumbing will also help you avoid accidents such as flooding caused by high water pressure leakage or burst pipes.

Spare at least 5 minutes of your time every month to observe your hot water units and see if there are obvious cracks or leaks. Lookout for unusual noises and be attentive for anything that might seem outside of the ordinary especially when you see that there’s a difference with how your plumbing works. If you think that your water bill is going through the roof, the water isn’t as warm as it used to be, or the pressure has dipped, it might be time to call a professional plumber for there might be something seriously wrong with your hot water system and you need to get it checked out.

Proposal disposal of hot water units must be done by a professional since this requires removing your unit from your pipe connection. Proper tools are necessary to not damage your plumbing and make installing a new hot water unit impossible. At The Plumbing and Gas Guys, we can properly dispose of your old hot water unit for free if you buy a new hot water system from our product collection. Our hot water system prices also include the installation rate so that all expenses are upfront. Our installation includes not only setting up the system and connecting it to your pipeline, but we also do tests to make sure that everything is in perfect working condition.

Make sure to keep the manual that comes when you purchase your hot water units to have information on proper hot water system maintenance at your disposal. But if you need maintenance assistance or want to discuss your hot water and plumbing concerns, connect with The Plumbing and Gas Guys on 1800 087 244. We supply and install hot water systems from trusted brands like Bosch, Dux, Quantum, Rheem, Rinnai, Stiebel Eltron, Therman, Vulcan and Wilson.

Plumbing Noises: What do they mean?

Plumbing Noises: What do they mean?

Pain is a good indicator that there must be something wrong with our body. For a domestic or a commercial establishment. hearing unusual noises might be a sign that there’s something wrong with the plumbing. Whether it’s a dripping sound or pipes banging, they aren’t just loud, they are also irritating, and you realise that it needs to be looked at.

It’s better to familiarise yourself with these plumbing noises so that the next time you hear them, you won’t just ignore these sounds. You can take the necessary steps to prevent further damage to your plumbing, for, when left unattended, can cause incidents such as a flooded basement or a leaking roof. 

Banging – can be heard when something that shouldn’t be on your pipe is stuck and is hitting the metal and even plastic pipes causing it to vibrate and produce the banging sound. When small debris accumulates, they will first float around and hit the pipes until they become large enough to cause a blockage. Too much water pressure and air entering the pipes can also create the banging sound.  

Clanking – happens when valves and knobs are loose allowing too much water pressure to be exerted on the pipes or the water heater tanks. 

Clicking – is often heard when a pump is waterlogged and is short cycling on and off. Thermal expansions of pipes can also create clicking noises when the heat rises from hot water heating baseboards. 

Dripping – means that there is a leakage in your plumbing. This is often heard from leaking water splashing the sink or when the drip is too fast and it creates a rhythm whether it exits from the faucet, the pipe, or the toilet. 

Glugging or Gurgling – can be heard from multiple plumbing points like the pipes, the vents and even the sewer line. This can mean that the pipes are either blocked with sediments like food wastes or small minerals, or air has somehow entered the system. For the sewer line, this can mean that tree roots penetrated the pipes and are blocking the flow of the water. 

Hissing – from a water heater tank means that there might be too much air disrupting the system. Hissing from the pipes means that there might be leakage and air is let through together with the water. 

Humming – is created when water pressure is too high, making the pipes vibrate when water is running. On the other hand, low humming from a running well pump or a circulating water heater pump is just normal – indicating that the system is activated and working well. 

Knocking or Popping – from a tank water heater is a sign of sediment buildup along the sides of the tank and the burner, reducing its efficiency and making it longer to heat the water, increasing your energy consumption. 

Rattling – happens when constant vibration of the pipes eventually displaces them from being mounted and fastened on ceilings and walls. When water is running through these displaced pipes, you’ll hear this loud rattling sound that’s a good indication that it needs to be mounted up, otherwise too much water pressure could make the pipe burst.

Squealing – can be heard mainly from loosened valves in faucets. It can also be heard from worn down plumbing furniture like washing machines and dishwashers. There might be some loose knobs and valves inside the machines that need tightening up.

Whistling – from your showerhead can be heard when some of the exit points are blocked with debris causing water pressure to build up and make the whistling sound as it looks for ways to release the water. 

If you hear these noises and are not sure of what to do, it is important that you immediately call a licensed plumber to check out the problem. While waiting for the plumbers and you know where the master switch is, turn off your water or gas line to avoid furthering the damage to the plumbing system. 

At The Plumbing and Gas Guys, our plumbing services cover domestic and commercial inhouse and outer plumbing.

Common Plumbing Misuse

Common Plumbing Misuse

We use our sinks, showers and toilets a couple of times every day but have you thought about whether these activities you’ve been used to are correct? Here are some of the most common misuse of plumbing utilities that though seemingly harmless, can lead to big plumbing issues that would require professional and prompt work.

Flushing food down the drain is one of the most common misuses of plumbing in the whole world. This is also the number one reason for blocked pipes and drains. If you still prefer to clean your plate of food waste down the drain, opt for sinks with waste disposal units which can catch the food waste and then eventually empty the bin through proper waste disposal means. Other garbage disposal units also have a grinding chamber where solid food waste is broken down to tiny particles which can then be washed away by the water and down into your drain. In addition to flushing food scraps down the drain, most people also choose to expel grease waste down the sink. Since grease might accumulate and eventually form a solid block that can clog your pipes, ask your plumber to install a grease trap under your sink which they can eventually empty out and properly dispose of in a couple of months or yearly. Have your drains and pipes occasionally serviced as well by professional and licensed plumbers to prevent major plumbing issues such as clogged sinks and burst pipes.

Flushing dead fishes and other small animals down the toilet is strictly discouraged and even illegal in some states! Some people believe that the best way to honour their dead fishes is to flush them down the toilet to bring them to the sea. This is a misconception because there is no guarantee that the fish will end up in the sea. For one, various plumbing systems work to separate the liquid from solid waste and thus your dead fish will just end up in a waste management facility provided that it survived the plumbing system and stayed intact. Flushing your dead fish and other small animals down the toilet can also cause bigger problems such as a blocked toilet or a burst pipe. For these cases, it’s best to bury your dead animal friends in your backyard where they can properly decompose and go back to the earth, or on a pet cemetery where they can properly rest in peace.

Since most people do not have a Plumber’s tape or a Teflon tape at hand, they use electrical tape to seal small cracks and leaks. Others also use materials such as packaging tape, duct tape and masking tape which are all temporary solutions to a problem that can burst when not properly addressed. For small cracks, use a Plumber’s tape or a Teflon tape to seal the gap. You can also use a PVC adhesive to fill the small gaps caused by the cracks. Remember to check up on the remedies that you have done for if there are still leaks from these gaps, it’s a sign that you now need to call a professional plumber to do plumbing maintenance and repair.

Some people do not shut off their plumbing during emergencies for fear of aggravating the issue. Plumbing emergencies can range from leaky faucets and continuously flushing toilets to burst pipes and broken water lines – which all consume copious amounts of water. If you are attempting to apply first-aid to a minor plumbing problem, you still need to shut off your plumbing especially if you do not know which caps or knobs release high water pressure. Never keep your water running during a plumbing emergency for you will not only flood your house but you shall also increase your water bill especially if it’ll take a long time for the plumbers to arrive.

When a toilet clogs, or when a pipe bursts, our first instinct is to apply some sort of first-aid. This can mean plunging a toilet or shutting off your plumbing and then sealing the bust pipe with PVC adhesive. When everything seems okay, most people tend to forget that what they’ve done is just a temporary fix and then they leave it at that before another bigger problem arises. DIY Plumbing is okay so long as it is only for minor plumbing problems like a slow draining sink or a clogged garbage disposal unit. But when it comes to crucial plumbing issues like broken hot water systems, clogged toilets and burst pipes, it’s necessary to call on professional plumbers since they have the knowledge and the tools required to fix these issues.

If you do not know the extent of the root of the problem, best let the professionals and the experienced plumbers fix your plumbing to avoid safety hazards and further the plumbing problem. If you call The Plumbing and Gas Guys on 1800 087 244, we can send a single or a team of our master plumbers depending on your requirement. From the simple leaking taps, to installation of hot water systems, to emergency plumbing jobs we cover all cities in Perth Metropolitan Area.

tree root cutting

Tree roots as small as thin hair fibres can enter pipes and cause blockage when they accumulate. Solid things that pass through your drain can also be trapped further causing blockage to your pipers. Call a licensed, professional plumber to assess your sewer lines, especially if you feel that your waste pipes start to drain slowly or give off an unpleasant odour.

It’s essential to clean your gutters every so often to remove falling debris such as leaves, tree roots, sand that accumulate and block your roof pipes and drainage. Roof plumbing, cleaning and repair are best done during spring and autumn.

Autumn Plumbing & Gas Maintenance Ideas for Perth Homes Energy-Efficient Hot Water Systems

Hot water system installations, especially placing a big tank outside or adding solar panels (for solar hot water systems) on the roof is best done after cleaning, and repairs to the roof are done to make sure that there’s good support for the system to be installed on.  


To prepare for the colder weather ahead, it’s best to have your hot water system checked and repaired during the autumn months.

Energy-Efficient Hot Water Systems

Energy-Efficient Hot Water Systems

The movement towards sustainable living starts at home with the use of energy-efficient household devices like solar pumps and heat pumps for hot water systems. Here at The Plumbing and Gas Guys WA, we make sure to provide different product options that our clients can choose from, especially if they are environmentally conscious. For our hot water systems, not only do we have the gas hot water system and the electric hot water system, but we also have solar-powered hot water systems and heat pump hot water systems which are both energy-saving and environmentally friendly house fixtures.

A solar hot water system uses converted energy from the sun to heat water for household use. Solar panels collect and convert the sun’s energy to heat cold water reserved in storage tanks on the roof or those with tanks on the ground. Solar hot water units include copper pipes where water is heated by the sun, and as a result, heating is circulated into and out of the storage tanks. A solar hot water system from one of Perth’s best plumbing and gas fitters is a wise investment because over time it will help save a large amount of money off your electricity or gas bill. As we are blessed with long sunshine hours in Western Australia, a solar hot water system will not only save you money, it will add value to your property. With expert local plumbers in Perth, The Plumbing and Gas Guys can help you retrofit your existing hot water system to an energy efficient solar-powered hot water system. Talk to our experienced local Perth plumbers for the best advice.

Heat pump hot water is very efficient and is often likened to solar power without the sun. Heat is absorbed from the air and transferred into your water by heat exchange.  While heat pump hot water units run on electricity, they are approximately three times more efficient than conventional electric hot water systems because they use less energy. And like the solar hot water system, the heat pump hot water system is also a good long-term investment as it’s cheaper to run allowing you to reduce your electricity and gas bills, with the added benefit of increasing the value of your home.

In choosing a hot water system, think of what’s most convenient for you – financially and environmentally. If you opt to have a gas hot water system or an electric hot water system, check out our blog about these hot water systems.

Gas and Electric Hot Water Systems

Gas and Electric Hot Water Systems

Recent research found that 2 out of 10 Australians love to take hot showers between 7 and 8 in the morning. This number rises especially during winter since we all can’t stand showering with cold water. A hot water system has become a staple in Australian homes as well as residential-commercial establishments like hotels and recreational properties. But did you know that there are many types of hot water systems you can choose from? We all know about the gas hot water tank system and the electric hot water system, but did you know that there are other energy-saving hot water systems powered by green energy like solar panels and heat pump?


Gas Hot Water System – uses natural gas or LPG to power a burner that heats water instantaneously (continuous flow system) or in water storage (hot water tank system). The continuous flow system allows for steady hot showers since water is instantaneously heated when it passes through burning copper coils. The hot water tank system heats the amount of water available on an insulated water storage tank. Hot water is consumable until you finish the water heated on the storage tank, but gas hot water systems do come in handy when your household suddenly lose electricity. If you wish to use a gas hot water system, contact a professional Perth plumber or a gas fitter to make sure that your pipe is connected to a gas supply pipeline. Compared to an electric hot water system, the gas hot water system is more expensive to buy and install, but it is generally cheaper to run in the long end.

Electric Hot Water System – uses electricity to heat water stored in an insulated tank (electric storage tank hot water system) or continuously heats water when required (electric continuous flow hot water system). Unlike gas hot water systems, electric hot water systems can be stored inside your house and does not require a gas pipeline when installed. Though electric hot water systems are cheaper to buy, running them is more expensive compared to gas hot water systems that’s why it is imported to go for electric hot water systems with high energy-saving properties, or they opt for more energy-sufficient electric hot water systems like those powered by solar panels or heat pumps.

Stay tuned on part 2 of our blog to learn more about more energy-efficient hot water systems like the solar hot water system and the heat pump hot water system!


In choosing a hot water system, think of what’s most convenient for you. If you don’t have the spare space to store a massive hot water tank storage, it might be better to go for the electric hot water system which instantaneously heats water. If you want to be energy efficient, invest in a solar hot water system or a heat pump hot water system.
