The recent outbreaks of hot water Legionella in Queensland mainly in hospitals is of concern. These, for the most part, were warm water systems 
which are not the same as your home hot water storage tank.
With hot or warm water systems there is always some risk but every system checked in recent weeks by Whywait Plumbing has had hot water temperatures that virtually eliminate all risk. However, there is almost no risk of you or your family contracting Legionella bacteria as a result of it breeding in your home hot water system.
Legionella Transmission Via Hot Water
Legionella transmission is airborne via respiratory droplets containing the bacteria. Warm water and domestic hot water systems that are contaminated will generally see the transmission of the bacteria in a shower that has not been used for a period of time.
Hot Water Preventative Measures For Legionella
Hot water systems should be maintained so that water at the point of use at any tap or outlet is 50°C or more after having been turned on for one minute.
Hot water systems should not be used until they have reached 50°C especially if they have been turned on for any period.
Generally, domestic hot water systems should have a temperature of 60°C or higher in water leaving the hot water storage tank.
DO NOT turn down the thermostat on an electric hot water storage tank to below 60C.
Hot Water Temperature For Preventative Of Legionella
Hot water systems should be maintained so that water at the point of use at any tap has a temperature that affects the survival of Legionella as follows:
- Above 70 °C – Legionella dies almost instantly
- At 60 °C – 90% die in 2 minutes
- At 50 °C – 90% die in 80-124 minutes, depending on strain
- 48 to 50 °C – Can survive but do not multiply
- 32 to 42 °C – Ideal growth range
- 25 to 45 °C – Growth range
- Below 20 °C – Can survive but are dormant, even below freezing
What Is Legionella Bacteria or Legionnaires Disease
What it is:
- Caused by the Legionella bacteria, commonly found in creeks, ponds and soil.
- Rare in people under 20 years, with those over 50 years old who smoke or have a weak immune system particularly susceptible.
Symptoms:
- Non-specific flu-like symptoms including fever, headache and muscle aches, developing within a week of breathing in the bacteria.
- Usually progresses rapidly with pneumonia symptoms, high fever, shortness of breath and chest pain typical.
Treatment:
- A person with the disease usually needs to be admitted to hospital for antibiotic treatment and care.
- Early diagnosis and antibiotic treatment important, and those treated usually begin to improve with three to five days.
Testing Your Storage Tank
For most homes, there is a very little risk of you having hot water legionella occur in your hot water storage tank unless you do really stupid things such as turn off your heating source.
An easy test of the storage temperature is to get a thermometer and test the temperature of your water from the overflow relief valve drain.
If you have any doubts about the temperature in your storage tank contact Whywait Plumbing to organise a service call to check your hot water system.

Judging by the number of phone calls in the last few days to Whywait Plumbing there is genuine concern amongst our clients over the threats posed to them from Legionella risk in their domestic hot water systems.
We can assure you whilst there is always some Legionella risk, there is almost no risk of you or your family contracting Legionella bacteria as a result of it breeding in your home hot water system.
The outbreak of Legionella bacteria in the hot water system at Wesley Hospital that killed a 60-year-old cancer patient and left a 46-year-old woman seriously ill has minor ramifications to be sure because all hot water systems can pose a risk.
That potential risk is why Whywait Plumbing is constantly advocating appropriate maintenance on your home hot water system to minimise that risk even further.
However, there is a huge difference between your home or domestic hot water system and the warm water recirculating system at Wesley Hospital. The Legionella outbreak in their warm water system has not been as a result of contamination in the hot water storage system or the hot water pipes but appears to be literally at the point of delivery from the shower where the water is cooler.
A warm water system is vastly different to your home hot water system with Wesley’s water temperature set between 42.5°C and 43°C. This is lower than the maximum 45°C legislated in the Plumbing and Drainage Act for hospitals. This low-temperature setting is a result of guidelines from Queensland Health that dictate hot water temperatures in hospitals be reduced to avoid the possibility of serious burns to young children and elderly patients. The downside of this requirement is that the possibility of Legionella bacteria surviving in reticulation pipes is increased. Water temperatures of around 46°C will kill legionella bacteria.
Warm water systems are typically found in care facilities, such as nursing homes, hospitals and child care centres, where water for purposes such as bathing and cleaning is provided at approximately 45°C to prevent scalding.
Your home hot water system if it is a storage tank is heating the hot water to between 60°C and 70°C. If you have a tempering valve or thermostatic mixing valve (TMV) installed then that has been set to deliver hot water at 50°C at each individual tap.
If you have no tempering valve installed, you virtually have eliminated all risk. But you have increased the risk of someone suffering a scalding from hot water. As always it is about managing risk.
However, there is an urban myth prevalent that you can reduce electricity costs by turning the thermostat down on an electric storage unit to 50°C. This is not recommended for many reasons but it will not save you electricity and to physically get a thermostat down that low requires physically breaking the locking mechanism on it that allows the setting to be between 60°C – 70°C. If you want to lower the delivery temperature the only acceptable and compliant method is to install a tempering valve.
In 99.99% of cases, the temperature ranges your hot water system operates in is almost certainly killing any Legionella bacteria. The risk if any, is after the storage tank in the reticulation pipes. By turning your shower on and running the tap with hot water first then cooling down with cold water to your desired shower temperature you are virtually eliminating what risk there is.
What the outbreak at Wesley Hospital has confirmed is that there is a risk from warm water and that maintenance of your hot water systems will manage and eliminate that risk.
What Whywait Plumbing do recommend is that you take advantage of our ongoing reminders and offers to service your tempering valves. This not only ensures that water is being delivered at 50°C but eliminates any possibility of Legionella. It also ensures you are complying with the requirements of most insurance policies in ensuring that routine maintenance is undertaken plus we provide you with a written report and a form 4 compliance certificate that is further evidence of your hot water unit being compliant.

Here at Whywait Plumbing we are often left wondering at the stupid things people do to their plumbing which ensures plumbers are never short of or will run out of work.
Essentially at Whywait Plumbing we are maintenance plumbing specialists and our primary work is to make house calls 24 hours a day, 7 days a week and 365 days a year. The basic reason plumbers never run out of work is based on two truths:
1) our clients will always need plumbing—or more specifically, plumbing that works—and,
2) some of our clients will always do stupid things that stop their plumbing from working.
Keeping in mind that the maintenance side of plumbing often requires a strong stomach and the need to suppress amusement with other peoples’ self-imposed misfortune. But rest assured that the two truths mentioned above will always ensure the plumbers at Whywait Plumbing will keep your plumbing working to keep your business. Listed below are samples of stupid things that some of our clients do to their plumbing that require Whywait staff to suppress their amusement or often bemusement.
- Leaving hoses connected and turned on at the tap and then going away on holiday. This is a classic plumbing error that one must assume is caused most often by extreme laziness with the only beneficiary being Gold Coast Water with all of the extra water this client ultimately had to pay for when the hose burst.
- Using the drain vent pipe for anything other than venting because there is plenty of room inside the pipe. This client was running TV aerial cables, pay TV cables and computer cables down the drainage vent pipe that come up through the roof. For this client it was the solution for getting all of the cabling into the house through a single 50mm pipe. But as he learnt vent pipes are not just there for their bad looks. Vent pipes not only provide air to drains inside the house and to prevent a suction effect that inhibits drainage but they also get rid of sewer gases that come up from the Gold Coast Water’s sewer main. If you cut a hole in your vent inside the house to run a cable through, you’re tapping into an endless supply of your neighborhood’s sewer gases. He had a nice picture on the TV in his lounge room with full access to the Internet but made the house almost uninhabitable with the fluctuating sewer gases entering the house.
- Using too much drain cleaner. When used judiciously and as directed on the right kind of blockage, drain cleaners can be effective and relatively safe for drains. When used with abandon, they can corrode some drain pipes such as copper which this client managed to achieve while making Bunnings very happy with all of his purchases. Plus so much was poured down the pipe it made the blockage worse.
- Pouring chemicals into a septic system. If you’re used to living with a septic system, you probably know how to take care of it. But this client was renting a house on acreage and did not think twice about using chemicals like drain cleaner, chlorine bleach, paint and even anti-bacterial soaps. These chemicals killed the essential bacteria in the septic tank, and caused it to stop working but of course waited until Christmas Day to finally block when he had a house full of family visiting.
- Screwing, nailing or cutting into a wall without checking for hidden plumbing pipes. The advent of multiple types of plastic water pipes have turned this into a nightmare for plumbers as they cannot be welded up like a copper pipe plus none of the systems are compatible. Doing this with a screw and you might hear a fine spray of water hitting the back of the wall. But this client did it with a chainsaw and got the ultimate gusher hitting not only the hot and cold pipes but also the hot water storage tank.
- Pouring cooking oil and fats down the kitchen drain. If you’re in the habit of pouring cooking oil and fats down the kitchen sink drain you are guaranteeing a drain blockage sooner rather than later. Cooking oil and fat is one of the best things for blocking drains as a recent client discovered managing to block up his entire unit and that of her neighbour in a duplex block on Australia Day when the neighbour was entertaining friends for a traditional barbecue.
- Putting everything down the kitchen waste disposal unit. Unfortunately this client was one of those people who thought a waste disposal unit was the equivalent of a space-fantasy laser gun. Unfortunately she found out it was not in the middle of a dinner party for important clients of her husbands business. A waste disposal unit is essentially a motor with a spinning wheel that has two metal blades, and it does very little to stop the following from blocking your drain even if you do run copious amounts of water into the kitchen sink: bulk flour, bulk rice, flower stems, prawn shells, oyster shells, filleted fish scales and skin and a couple of spoons. The smell was not great either.
- Using the toilet as a rubbish bin. We all know it is stupid to put a lot of solids or newspaper down the toilet but many people do it anyway. This client like many others we rescue believed that if she could just get it to flush away it would be magically out of her life forever. Like many people she had the mistaken belief that at the other end of the toilet there is nothing but a black hole which is a portal to a subterranean outer space that swallows up everything she could discard and it is then whisked off into oblivion. Unfortunately, that oblivion is a 100mm pipe that leads into another 100mm pipe, which was the drainage pipe to her entire house. In other words constantly flushing incorrect items down the toilet over an extended period ultimately caused the entire house to block up and the drain had to be dug up to remove all the solidified debris that had mounted up. The bottom line is if it is not toilet paper or faeces or urine it does not belong in the toilet pan.
And those are just a few of the stupid things we have rectified this year to date at Whywait Plumbing Services.

Recently here at Whywait Plumbing, we have had several calls from clients who are concerned they are about to be overrun by small drain flies in their bathroom. Generally, the concern is that they are in large numbers, and no matter what is done to kill them, every drain fly seems to multiply as there is always more the next day.
Cleaning Your Drains Doesn’t Get Rid Of A Drain Fly
Many clients had cleaned the bathroom until it could be cleaned no more. So by process of elimination, they had decided that they were coming out of one of the drains in the bathroom. Frustratingly no matter how often some clients sat and observed the drains, they never saw any of the drain flies emerging from the drain in the shower or basin or the floor waste. Many clients describe them as lazy flies, accumulating on the bathroom walls and seldom flying.
Most people observed that the flying drain flies were mainly sitting on the walls or ceiling in the bathroom. We can confirm that everyone was experiencing what is commonly known as drain flies or bathroom flies emerging from the floor waste drain where they breed.
What Do Drain Flies Look Like
A typical-looking drain fly on a bathroom wall
Drain flies are dark grey and 2mm – 4mm long with hairy moth-like wings. They have a jerky flight as they are weak fliers and usually are found close to the floor waste drain or other areas of origin, such as the shower or bath waste. This is why they seldom stray outside the bathroom. In most cases, they are breeding in the bathroom floor waste trap.
Drain flies do not bite and are not known to transmit diseases of any sort. They do not damage clothes or linen and are considered to be more of an unsightly nuisance value in your home.
The adult drain flies and larvae can be controlled by eliminating or reducing breeding sites. If the infestation is minor, pouring bleach into the floor trap will usually kill them. However, if that does not solve the problem, then you will need to kill them by thoroughly cleaning the drain lines and or sealing the floor trap.
They continually seem to be in large numbers despite always killing them because eggs hatch in 32 to 48 hours when the temperature is above 20 degrees. The larvae mature in 9 to12 days and feed on the decaying organic matter that accumulates in the floor waste trap. The life cycle of drain flies is 1-3 weeks. Adults drain flies live about two weeks, with old ones dying and new ones emerging. They feed on the wastewater in the floor waste trap. During the day, the adults rest in shaded areas under the basin or on walls near plumbing fixtures and showers and baths. Most activity occurs during the evening when the flies are seen hovering about.
Septic Tanks Breeders
If you are on acreage and have septic tanks or treatment plants, they may breed in large numbers in and around the tanks. Drain flies may be carried by prevailing wind to nearby homes up to 3 kilometres away. Adult drain flies are small enough to pass through ordinary window insect mesh screens.
Thorough Cleaning of Drains and Traps
It is the experience of Whywait Plumbing that cleaning the drains from the basin, shower and bath that discharge into the floor trap is only part of the answer. It is also beneficial to clean the floor waste trap and grate thoroughly. We recommend cleaning the whole area with No–Rinse Floor Cleaner, Sanitiser & Disinfectant, which will clean and disinfect the floor and drain. We don’t recommend the need to continually pour chemicals such as bleach down the drain as it is washed away as soon as you use any water in the basin or shower fixtures.
Drain PRO™ – The Drain Fly Solution
In 2010 Gary and Michele Mays, the owners of Whywait Plumbing Services, went through this entire experience of drain flies invading their ensuite bathroom. Gary Mays installed a Drain PRO™ unit into the floor waste, which prevents not only drain flies but also bacteria, odours and insects from exiting through the drain into the bathroom.
It is three years since the installation of the Drain PRO™ units in all of the bathroom floor traps in their home, and they have eliminated the reoccurrence of the annoying tiny lazy drain flies.
If you are experiencing the annoyance of drain flies that will not go away, call Whywait Plumbing at (07) 5580 4311 to book a service call so we can eliminate them once and for all.

At Whywait Plumbing the phones began to ring as soon as the water bills from Gold Coast Water arrived in late January. The most common issue was one of bill shock where residents received bills in the thousands of dollars when their normal bill was around $600.
This was brought home to us here at Whywait when our IT Manager, Brad Horrocks rang about the bill his pensioner father, Neal had received which was $4980 when his normal bill was never over $600. Unbeknown to Neale he had an underground leak in the polypipe watermain coming into his home in Coombabah. This unfortunately is common in the coastal areas such as Coombabah where the water basically soaks into the sandy soils rather than bubbling to the surface.
Neal was fortunate that Gold Coast Water gave him a rebate of $3658 but he was still left to pay a bill of $1322. The sting in the tail of this rebate is that Neale is not eligible for further rebates should he have further leaks in his watermain for 3 years. This puts Neale and all of those like him who are recipients of the 60% rebate from Gold Coast Water where the bill shock is caused by a broken pipe in a terrible dilemma. This is caused by water meters only being read every 3 months and bills being issued every 6 months.
Unless you read your water meter on a regular basis which we strongly recommend then you can suffer a major break in your watermain and not be aware of it for at least 90 days when you receive a letter from Gold Coast Water advising you that you have very high water use readings. If you have already used your once every three years rebate for broken pipes then you will pay for every litre of water that leaks into the ground.
However we do have a solution for everyone who has experienced the drama of water bill shock. Prevention is always the best solution. AquaTrip water leak detection and control systems are the solution. AquaTrip is a permanently installed leak detection protection system that quietly provides protection in the background and under normal conditions you will never know it’s there.
AquaTrip monitors the flow of water into your property, and will shut off the water automatically in the event of a tap left running, a burst pipe, or if a tap, fitting, pipe, toilet, cistern or appliance is leaking. This will save water, reduce wastage and most critically minimise property damage.
AquaTrip is an active water leak detection system that costs less than the excess charges from Gold Coast Water or the excess on one insurance claim and a fraction of the cost of most annual home insurance premiums. In most cases insurance companies do not cover the cost of watermain leaks or the resultant water costs. AquaTrip will provide your home with a lifetime of protection against such water leak events. AquaTrip is a one time insurance policy.
If Neal Horrocks had an AquaTrip installed he would not only have the peace of mind provided by AquaTrip but would be potentially $700 better off today as he would not have had to pay a water bill of $1322.

Cheap plumbing fixtures on-line and the desire for a bargain has created an on-line love affair to compare prices of supposedly comparable products and services.
It is a guarantee no matter how much you pay for any product or service you will always find it cheaper on-line. This has given rise to an increasing belief by many consumers that they have paid over the odds and have been ripped off because they found allegedly the same product or service on-line “cheaper”.
It is worth remembering that “cheap” has two meanings. Where plumbing products and services are concerned “cheap” is responsible for some colossally expensive problems. In fact a large amount of work undertaken by Whywait Plumbing is because of consumers who took the “cheap” option. The old adage that you get what you pay for is certainly truer today than at any other time in our history.
Plumbing products that are sold in Australia are subject to stringent testing, designed to ensure that they meet Australian Standards. Once plumbing products meet the required Australian standards they are granted a WaterMark. The product whether its a tap or a toilet or a hot water service or a urinal must display the WaterMark logo as pictured to the right on the product by law.
If you are buying plumbing products on-line from overseas or if your builder or plumber is doing this to cut costs then it is a sure bet that it will end up costing you much more than the money saved in repairs and replacement.
Always make sure you understand what you are paying for and ensure that it has a compliant Australian WaterMark approval. Using a non compliant non WaterMark approved product will null and void your insurance policy if the product is defective and causes property damage.
When you are upgrading or replacing or renovating you will comes across a lot of great looking plumbing products to select from and ones that make great claims in terms of durability and long-life. Usually they are much “cheaper” and are tempting to purchase for the price being offered. Generally where mixer taps and toilet suites are concerned the cheaper the price means corners have been cut in their production. If you cannot see the WaterMark on the product then do not purchase it.
Unfortunately in Australia it is not illegal for non compliant products to be imported and sold. It is however illegal for plumbers to install them. Listening to unqualified salesman who tell you how wonderful the cheap plumbing product is have lead many people to have expensive repairs undertaken. It is always best especially if renovating to stipulate any product supplied for your job meets or exceeds the relevant Australian Standard and or WaterMark for plumbing products.
