Are these tiny flies coming out of my bathroom drains drain flies?

Yes the tiny flies in your bathroom are drain flies

Last week Lynette, who is one of our Service Partner clients, sent me a photo of her bathroom floor enquiring whether I knew if these tiny flies seemingly coming out of her bathroom drains were drain flies. My simple reply was yes as they are more prolific in spring and summer when temperatures exceed 20°C.

The photo above is dramatically magnified to illustrate the number of drain flies in a small area.

Lynette was concerned that no matter how many times she sprayed the flies to kill them, there was always more flies the next day. In fact, what disturbed Lynette the most was that they just appeared to multiply and accumulate on the walls and floor but only in the one bathroom. The flies were nowhere else in her home or in the other bathrooms.

Cleaning your bathroom won’t eliminate drain flies

Lynette was exasperated and frustrated that no matter how often she cleaned her bathroom, the drain flies just kept returning and multiplying.

She repeated to me what I’ve heard multiple times over the years, that she would clean the bathroom with a powerful supermarket bleach cleaner and by the next day the drain flies would have returned.

A friend had told her to buy a 2.5-litre container of bleach and pour it into all her drains in the bathroom which would kill the flies within 24 hours. After using all 2.5 litres of bleach the drain flies were still there.

What are drain flies?

Drain flies are more annoying than anything else as the sheer numbers in your bathroom are unsightly creating, an illusion that the bathroom is not clean.

They do not bite nor do they transmit any diseases of any sort. Nor do they damage clothes, towels or linen. 

Drain flies are prolific breeders which is why people like Lynette get frustrated as the more she appeared to kill, the more prolific they became.

The flies themselves are only around 3-4mm in length being dark grey in colour with hairy moth-like wings which as you can see in the photo below dominate their body size.

Why do drain flies only appear in bathrooms?

If you don’t live on an acreage block with a septic tank or sewer treatment plant, then the only place you will probably experience drain flies is in a bathroom. In septic tanks of sewer treatment plants drain flies breed prolifically but don’t stray far from the tanks which are their food source.

In bathrooms, the flies during the day appear to do nothing other than just sit on walls or under the vanity basin or on the ceiling. This is because they are more active at night, which is why you will seldom see them flying or actually emerging from you floor waste drain.

Even though they are poor fliers the flies are frequently transported by the wind away from septic tanks or sewer treatment plants for distances of 3-5km. This can allow them to enter your home through your insect screens as they are small enough to get through the holes in the mesh. Ultimately they will search for your bathroom floor waste drains because this is where they can feed and breed.

Where do drain flies live and breed?

Since drain flies are such poor fliers, they will always be found within a few meters of the bathroom floor waste drain. This is why you only ever appear to see them in a bathroom.

Infestations occur once temperatures exceed 20°C in spring. The rationale that they keep multiplying is not misplaced as their life cycle is 1-3 weeks from eggs hatching to becoming adult flies. They are prolific breeders with eggs hatching within 48 hours to become larvae. The larvae then mature within 12 days feeding on the decaying organic matter in the bathroom floor waste drain. The adult flies emerge from the drain at night that you then see on your bathroom walls and ceilings will live no longer than 2 weeks.

How you can eliminate a drain fly infestation in your bathroom?

Controlling and eliminating adult drain flies and larvae is by eliminating breeding sites in your bathroom drains. The pouring of bleach into the floor waste trap will typically work if you have a minor infestation.

A major infestation will not be solved by bleach as you need to thoroughly clean the and seal the floor waste trap to eliminate their food source and breeding ground.

From experience, we have found cleaning the whole area around the floor waste and inside the drain with Aquatemp Surface Sanitiser & Disinfectant will clean and disinfect the drain flies breeding ground and food source. 

If you are experiencing the annoyance of drain flies that will not go away give us a call at Whywait Plumbing on (07) 5580 4311 to book a service call so we can eliminate them once and for all.

Aquatemp Surface Sanitiser & Disinfectant 1 Litre Spray Bottle $36.92

Aquatemp Surface Sanitiser & Disinfectant comes in a ready to use spray bottle that eliminates the drain flies food source and breeding ground effectively plus sanitises, disinfects and protects for up to 24 hours.

WaterMark Certification Guaranteeing Community Health and Safety

WaterMark Certification Guaranteeing Community Health and Safety

The WaterMark Certification Scheme Is Ultimately About Your Health

The WaterMark Certification Scheme is not voluntary. It is a mandatory and legally enforcible certification scheme covering Australia for all plumbing and drainage products. Ultimately it is about guaranteeing community health and safety.  

Bear in mind the water you drink, cook with and wash in can conceivably transmit waterborne diseases if the water becomes contaminated. This is a major reason why all products such as taps you drink from must be WaterMark approved.

Every product that is intended for use in all plumbing and drainage installations must undergo a risk assessment to identify any potential risk of manufacturing faults and installation failures.

Looking for the WaterMark 

When purchasing any new plumbing products for your home such as taps or toilets you must check that the products you are buying or installing are certified for use in Australia?

Certified products are easy to identify by the WaterMark certification trademark logo, as illustrated below. The WaterMark logo must appear on a product or its packaging, in addition to its WaterMark licence number and the applicable product specification.

Regrettably, many people go online to buy “cheap” plumbing products especially taps. Few of these taps have WaterMark Certification and potentially can be manufactured with large amounts of lead in the metal.

Deplorably there are many companies in Australia who think they can ignore their responsibilities to obey the law where WaterMark Certification is required in the pursuit of profits. Online sales of what are technically illegal plumbing products are rampant. There are advertisements all over social media promoting the purchase and DIY installations of non WaterMark approved products such as My Bidet Australia.

WaterMark Awareness

The WaterMark Certification Scheme is administered by the Australian Building Codes Board or ABCB as part of the Plumbing Code of Australia or PCA.

With all of the issues surrounding COVID-19 earlier this year, the ABCB along with the QBCC and Queensland Health became very concerned about online purchasing of bidet seats, tap, shower, toilet and urinal products on eBay and other online stores.

This resulted in the ABCB rolling out the LOOK for the WaterMark campaign. The campaign aims to improve compliance with the PCA, by promoting the WaterMark Certification Scheme to increase the understanding of why products must have WaterMark.

The LOOK for the WaterMark campaign will be implemented as a succession of WaterMark promotions with three key messages:

  • WaterMark certified products are all marked with the WaterMark trademark logo, WaterMark licence number and applicable specification.
  • Plumbing work must be undertaken by licensed plumbers who are legally required to install only WaterMark certified products.
  • How to search the WaterMark product database to locate and verify all WaterMark certified products.

What is WaterMark?

The video below explains exactly what the WaterMark Certification Scheme is and why we have it to protect your health.

What Plumbing Products Require WaterMark?

The video below explains exactly which plumbing products are required to have WaterMark Certification and how you will know if the product has been certified.

How to Use The WaterMark Product Database

The video below explains how to search for plumbing products WaterMark Certification on the WaterMark Product Database so that you can verify if the product has been certified.

Responsibility for Supply & Installation of WaterMark Approved Products

Enforcement of most laws concerning plumbing and plumbing products lays with the Queensland Building and Construction Commission or QBCC.

As Licensed Plumbers, it has always been illegal for us here at Whywait Plumbing to install non WaterMark approved products and non-conforming plumbing products. Since 2017 it has been illegal for anyone to supply a non-conforming plumbing product.

At Whywait Plumbing we have always complied with the laws that pertain to plumbing products. We will notify the QBCC immediately whenever we discover non-conforming, non-compliant illegal plumbing products installed anywhere.

Ultimately all of these laws are for your protection, safety and the security of community health.

Non-Conforming Plumbing Products

Non-Conforming Plumbing Products

Non-Conforming & Non-Compliant Plumbing & Building Products Are Illegal To Supply, Specify & Install

Non-conforming plumbing products that have not the appropriate WaterMark certification have always been illegal for licensed plumbers to install.

The WaterMark Certification Scheme is not voluntary. It is a mandatory and legally enforcible certification scheme for plumbing and drainage products. This is to ensure they are fit for purpose plus appropriately tested and authorised for use in all plumbing and drainage installations.

non-conforming plumbing products have never been installed by Whywait PlumbingIt has been illegal since 2017 for anyone to supply, specify, instruct others to install or for anyone to install non-conforming plumbing and building products in Queensland. Unfortunately, many companies think they can ignore their responsibilities to obey the law. Online sales of non-conforming plumbing products are rampant. There are advertisements all over social media promoting DIY installations of non-conforming plumbing products such as My Bidet Australia.

On 30 August 2017 the Building and Construction Legislation (Non-conforming Building Products-Chain of Responsibility and Other Matters) Amendment Act 2017, regarding the use and sale of non-conforming building products became law.

These laws further strengthened how compliance must be achieved with amendments to the Queensland Building and Construction Act 1991, the Plumbing and Drainage Act 2018, and the Building Act 1975 concerning non-conforming building and plumbing products.

These laws create a chain of responsibility so that designers, manufacturers, importers and suppliers of plumbing and building products have as much responsibility as licensed plumbers to ensure a product is compliant and fit for its intended purpose.

These laws give the Queensland Building and Construction Commission (QBCC) new powers to investigate the manufacture, sale and use of non-conforming building products.

Building and plumbing products are regarded as illegal, non-conforming or non-compliant for an intended use if;
  • the product is not, or will not be, safe; or
  • does not, or will not, comply with the relevant regulatory provisions; or
  • the product does not perform or is not capable of performing, for the use of the standard it is represented to conform by such as Watermark certification.

Definitions of Non-Conforming Plumbing Products

There are 1000’s of plumbing products manufactured both in Australia and overseas. Consequently, it can be challenging to know whether or not a plumbing product is genuine and will perform as required plus will comply and conform with the WaterMark Certification Scheme.

non-conforming plumbing products have no WaterMark logoYou can check the WaterMark Product Database which lists all plumbing products that have been certified and marked in accordance with the requirements of the WaterMark Certification Scheme.

In general, everyone should be aware of the following terms regarding compliant plumbing products:

  • Non-compliant plumbing and building products and materials are any product used in situations where they do not comply with the requirements of the National Construction Code (NCC) which encompasses the WaterMark Certification Scheme. You must be aware any plumbing product can be both non-conforming and non-compliant.
  • Fraudulent documentation refers to a recorded claim that a plumbing product’s performance meets specified Australian plumbing standards when used or tested, do not meet that performance claim. This frequently will include falsified documentation, fraudulent certification or test results.
  • Product substitution is commonplace and can occur when a product is submitted for third-party certification testing and, after the WaterMark certification is granted, the manufacturer/supplier alters it and does not retest or recertify the product. Product substitution is also a widespread problem where a seemingly identical but non-conforming replacement plumbing product is offered to replace the WaterMark certified product.
  • Counterfeit plumbing products are also widespread and are an unauthorised copy of a plumbing product, created with the intention to deceive. They are illegally sold to suppliers, plumbers, building owners and consumers, as genuine.

Responsibility

These laws have created a legal chain of responsibility for everyone for reporting non-conforming building or plumbing products to the QBCC. This duty applies to every person in the chain of responsibility who becomes aware or reasonably suspects that the building or plumbing product installed is non-conforming and or non-compliant for the intended use.

As Licensed Plumbers, it has always been illegal for us here at Whywait Plumbing to install non-conforming plumbing products. However, it is now illegal for anyone to supply a non-conforming plumbing product.

At Whywait Plumbing we have always complied with these laws. We will notify the QBCC immediately whenever we discover non-conforming, non-compliant illegal plumbing products installed anywhere.

Ultimately these laws are for the protection, safety and security of everyone.

It is Illegal to Install a Douche Spray or Bidet Spray

It is Illegal to Install a Douche Spray or Bidet Spray

It is illegal to install a douche spray or bidet spray in Queensland unless it complies with AS/NZS 3500.1:2018 clause 12.2.3 below which classifies bidet toilet seats and douche sprays at toilet seat douches.

12.2.3 Toilet seat douches – Where the douche outlet, in all positions, is at least 25 mm above the overflow level of the pan, backflow prevention is not required. Where the douche outlet, in any position, is less than 25 mm above the overflow of the pan, a high-hazard backflow prevention device, conforming to AS/NZS 2845.1 or AS 2845.2, shall be installed. This device shall be either part of the douche or installed separately.

It is illegal to install a douche spray or bidet spray in Queensland unless it complies with AS/NZS 3500.1:2018 clause 12.2.3 contact Whywait Plumbing for a legal installationIt is entirely illegal to undertake a DIY installation of douche spray or bidet spray despite what you may read on social media.

Yes, they can be legally installed by a plumber provided they are installed with compliant backflow prevention valves and registered with Form 9 at City of Gold Coast or Logan City Council plus lodgement of Form 4 with Queensland Building and Construction Commission. These requirements are not optional; they are required under law as per the Plumbing and Drainage Act 2018.

Illegal bidet seat attachments

Unfortunately, there are advertisements everywhere on social media or websites promoting DIY such as My Bidet Australia. The product they advertise as an easy install toilet seat bidet is illegal. They promote on their website as – Quick and Easy Installation: Includes everything you need including tools to get your bidet up and running in minutes. Easily attaches to and detaches from any standard two-piece toilet.

illegal toilet seat bidet from https://www.mybidetaustralia.com.au/bidet-australia which Whywait Plumbing would never installThe reality is the product has no WaterMark certification. As the photo illustrates clearly on their website, the dual nozzles are deep inside the toilet bowl, creating a high backflow risk. This is categorised as high risk as back-siphonage can occur through these nozzles allowing contaminated water from the toilet bowl to be sucked into the potable or drinking water supply.

The toilet seat bidet from My Bidet Australia sells online for $99, which is an indication of its quality. The price should be a warning enough as to how good this product is likely to be as good quality WaterMark approved bidet seats such as a Toto Washlet start at around $1199.00 in Australia.

The old saying you get what you pay for applies absolutely for this dangerous product. It is frightening that they state on their website – Upgrade your bathroom with beautifully designed bidet attachments, featuring water pressure control knobs. We use high-quality parts that are built to last. They are constructed with high-pressure faucet quality valves and metal/ceramic core. Common sense dictates you cannot produce high quality for $99 that complies with Australian Standards.

Unfortunately, this product is being advertised everywhere on Facebook and Google. Currently, if you do a Google search for a Toto bidet seat the first result in Google AdWords is incredibly for not Toto but My Bidet Australia. It truly is a case of buyer beware and why you need to check it is approved for use in Australia with a WaterMark certification.

An illegal toilet seat bidet or Douche Spray or Bidet Spray can kill you so call Whywait Plumbing today

What does backflow mean?

Backflow is simply the reverse flow of water. When we refer to it in plumbing terms, it is stopping contaminated water being drawn back into the water supply system that we all use for drinking. In terms of an illegally installed douche spray or bidet spray, this can occur when the water pressure drops significantly. If nozzles or sprays connected to the water supply are in contact with a contaminated water supply in a toilet, there is potential for that contaminated water to be sucked into the drinking water supply. In simple terms, it is like you sucking on a straw.

There are two ways that backflow contamination will occur because of a water pressure drop:

  • Back-pressure occurs if there is an increase in the downstream pressure, which creates a reversal of the normal direction of the water flow.
  • Back-siphonage occurs when there is a drop in the supply pressure, thereby creating a negative pressure situation in the water supply. Commonly this will happen if the water is suddenly turned off or there is a dramatic increase in demand such as water used for fire fighting.

With a bidet seat, douche spray or bidet spray backflow contamination is possible and if occurring it is classified as high risk. This is why all of these products by law must be:

  • installed by a licensed plumber
  • have WaterMark certification
  • have a testable backflow valve installed such as an RPZ valve
  • have a Form 4 lodged with QBCC
  • have a form 9 lodged with the local water authority

All of the above are requirements under the law; they are not optional extras.

What does high hazard mean?

High hazard is the highest rated hazard in the cross-connection hazard rating in AS/NZS 3500.1-2018, which is covered in Section 4 Cross-Connection Control and Backflow Prevention. As Licensed Plumbers, we know how serious this section is in ensuring that our drinking water is not contaminated and potentially life-threatening. Clause 4.3 below lists all three ratings:

4.3 CROSS-CONNECTION HAZARD RATING
Cross-connections are rated using three degrees of hazard, as follows:
(a)      High hazard     Any condition, device, or practise that, in connection with the water supply system, has the potential to cause death.
(b)      Medium hazard    Any condition, device, or practise that, in connection with the water supply system, has the potential to endanger health.
(c)       Low hazard     Any condition, device or practise that, in connection with the water supply system, constitutes a nuisance but does not endanger health or cause injury.

The high hazard rating is not a scare tactic when we talk about an illegal or a non-compliant bidet seat, douche spray or bidet spray it is a health issue with the critical wording being potential to cause death.

As Plumbers, we are not over sensationalising the dangers of DIY installation of a bidet seat, douche spray or bidet spray. We are just telling you this is the legal requirements as per the Plumbing and Drainage Act 2018.

Can a DIY installation effect insurance policies?

Yes, any plumbing fixture installed in your home or business can null and void your home and contents insurance policies.

Any bidet seat, douche spray or bidet spray that is not installed by a Licensed Plumber or does not have WaterMark certification has the potential to flood your home. A burst flexihose on these dodgy products can flood your home very quickly.

ACCC and Government warnings

We all understand that COVID-19 has caused a great deal of uncertainty and angst, but a DIY installation of a toilet bidet seat or douche spray or bidet spray is merely breaking the law. DIY of any plumbing fixture has potentially dire consequences, and with products such as the toilet seat bidet from My Bidet Australia, you are risking severe illness or death.

It has become so intense of a concern that the Australian Consumer Competition Commission (ACCC) has issued an alert concerning the supply and installation of bidet products. The ACCC, in consultation with the ABCB or Australian Building Codes Board and Standards Australia, has published a joint warning, COVID-19: Supplying and installing bidet products on the Product Safety Australia website.

The ACCC, the ABCB and every state government has become alarmed that the COVID-19 pandemic has seen a dramatic increase in the purchase of toilet seat bidet douches, handheld bidet sprays and trigger sprays, and other bidet type products that are connected to toilet water supply valve are being installed as a DIY project.

The critical message of every alert issued by every state government is that the installation of any bidet product connected to the drinking water supply must be undertaken by a licensed plumber and must hold WaterMark certification.

DIY installations of bidet seats and douche sprays

DIY installations of bidet seats and douche sprays

The DIY installation of a bidet seat or a douche spray is illegal. The health risk of incorrectly installed bidet seats or douche sprays can be severe not only to you but to the community as a whole. In the last month, Google searches for the term bidets have increased tenfold, which is frightening as traditionally Australians have shunned the installation of bidets. The increase in Google searches has occurred due to multiple social media posts and newspaper articles on so-called alternative toileting devices and what is appallingly lousy advice on their installation.

The multitude of bidet seats and douche sprays that can now be found for sale online has set off alarm bells at all levels of government in Australia. It is evident when checking the scant information available online that very few of these online products have been tested and approved for use in Australia.

Hardware stores and specialist plumbing suppliers that stock douche spray kits are selling them out as fast as stock arrives to DIY enthusiasts who get installation advice from shop assistants. This just increases the health risks tenfold. There have been reports of staff in plumbing supply stores being abused for refusing to advise on how to install bidet seats or douche spray kits and suggesting that a licensed plumber must install these products.

Whywait Plumbing can legally install a douche spray to your toilet to protect your families healthAs a result, here in Queensland the QBCC has issued a public warning on the sale and installation of ‘alternative toileting devices’ which in part states:

This is a warning issued by the Commissioner of the Queensland Building and Construction Commission (QBCC) to the public under section 20J(1)(i) of the Queensland Building and Construction Commission Act 1991 (QBCC Act).

The QBCC warns suppliers and the public about the sale and use of potentially non-conforming building products, namely Do It Yourself (DIY) bidets, douche sprays and similar hygiene devices, collectively known as ‘alternative toileting devices’.

The QBCC has recently become aware of the sale and DIY installation of alternative toileting devices in Queensland, particularly for household use. Unless these devices are manufactured to comply with Australian Standards and also are properly installed, these can lead to a risk of contaminating the household water supply with E. coli bacteria. An E. coli infection can lead to serious health and safety issues.

In Queensland, alternative toileting devices must be installed by a licensed plumber who has the skills and qualifications to ensure that a backflow prevention device is in place.

Whywait plumbing only install WaterMark certified bidet seatsA bidet seat or a douche spray are classified as high hazard plumbing products. This is because there is a high risk of toilet sewage water mixing with your drinking water if they are not installed as per the requirements of section 12 of AS/NZS 3500.1-2018 Water Services. They must be legally certified with an Australian WaterMark approval which is evident on the packaging plus can be searched online at the WaterMark Product Database.

Despite looking easy to install, they are not. Both a bidet seat and a douche spray require a water connection. Generally, this can be at the water connection for the toilet cistern. However, this always requires a legally compliant backflow prevention device to be installed as well. This is not an optional extra it is the law to prevent your drinking water from becoming contaminated, which pose serious risks to your families health and safety.

If you have recently undertaken a DIY installation of a bidet seat or douche spray to your toilet, then we urge you to call us on (07) 5580 4311 to get us to check it is a compliant installation. This ensures you have not created a risk to your families health and safety plus ensures you have not null and voided your homes insurance policies.

You need to be aware of so-called unlicensed plumbers or handyman who cannot legally install a bidet seat or douche spray to your toilet. Beware of the handyman who tries to convince you that he can undertake plumbing works as long as it’s under $3300 of value. This is a complete lie by opportunistic unlicensed scammers who put your families health at risk. The benchmark value for undertaking plumbing, drainage or gas work is $0 and always has been. For extra assurance go the QBCC website  To find out more about a licensee you can use their online licensee search, or search their occupational licence.

If you would like to investigate the installation of a bidet seat or douche spray to your toilet, then call us on (07) 5580 4311 to book an appointment. This ensures the installation is compliant with Queensland law as all products we install have appropriate and genuine Watermark certification.
