Aidan Clarke
Drain odours have plagued Aidan Clarke the owner of Marine Energy Systems at Murarrie since 2006. Since opening his workshop and showroom, he had been trying to solve the problem of foul odours in their bathroom. The smell was so bad that employees had complained that it was making them nauseous.
ADCO Constructions, the builder of the complex, had organised their plumber to replace the drainage connection for the toilet suite to no avail. Odour blockers had been placed in the bathroom, but they too were of limited value and failed to address the problem with drain odours continually there.
The problem was particularly acute after weekends with the door having to be jammed open on Monday to get fresh air into the bathroom. The problem was particularly embarrassing when clients of the company viewing product in the showroom needed to use the bathroom.
In May 2011 in absolute frustration, Aidan Clarke contacted Gary Mays of Whywait Plumbing to solve the drain odours problem. After a thorough inspection of all existing drain connections to the toilet, shower and basin it was concluded that the only logical place that the drain odours could be emanating from was the floor waste trap in the middle of the floor.
As a result, Gary Mays from Whywait Plumbing Services contacted John Carroll from Eco Guardians to obtain his advice to see if a new product he had discussed with Gary Mays previously would solve the problem. A DrainGuardian™ was supplied to us to fit into the floor waste. The DrainGuardian™ was installed in less than 5 minutes, replacing the existing grate cover.
Once installed water was poured down the floor waste ensuring there was a water seal in the DrainGuardian in addition to the existing water seal in the main 100mm trap that makes up the drainage floor waste system.

DrainGuardian™ eliminating drain odours from floor wastes
The entire process of installation was completed to ensure the sceptical, long-suffering Aidan Clarke that the DrainGuardian™ would provide greater protection to any form of odour emission from the floor waste and end the problem he had been enduring.
The DrainGuardian™ works by creating two physical barriers to smells and vermin while it also kills airborne bacteria, waterborne bacteria and fungi. In the smelly bathroom at Marine Energy Systems the improvement was immediate and permanent.
The results were almost instantaneous as within one day the DrainGuardian™ had eliminated odour problems in the bathroom. The elimination of the odours in such a short time proved conclusively the problem that Marine Energy Systems had been enduring since 2006 had been the floor waste trap all along. There was nothing structurally defective with the floor waste trap that was causing odour emission’s which makes the source of the odours a common problem we find these days in that it is a venting problem in the entire sewer drain system to the property. What had been happening was a siphoning effect that caused the floor waste trap to be sucked either completely or partially dry that allowed drain odours to be emitted through the floor waste and into the bathroom.
Aidan Clarke now categorically states, “ DrainGuardian™ should be compulsory in every floor waste in every bathroom as a clean bathroom environment cannot be underestimated. I have wasted incredible amounts of money on trying to solve this problem as it was a cause of acute embarrassment to me, our staff and to clients. Our bathroom is now a pleasure to enter with there being no drain odours at all thanks to a straightforward solution in DrainGuardian.”

With the advent of the EnviroSeal system for Zero Flush waterless urinals the days of malfunctioning urinals are over. The ongoing development of Zero Flush waterless urinals signals the end of wasted water and energy in public toilets everywhere. Building owners everywhere are praising the benefits and reaping the rewards of finally having efficient, problem free waterless urinals installed by Whywait Plumbing Services.
For those who are not aware, a Zero Flush waterless urinal utilises gravity and an incredibly smooth porcelain surface to do the work that used to take up to 12 litres of water. While this concept may seem foreign and completely unappealing, a Zero Flush waterless urinal eliminates odour by separating waste from air meaning that foul smells will stay in the drains where they belong.
Zero Flush waterless urinals have hygienic benefits, economic benefits, and environment benefits, some of which are listed below:
- No flushing: When a traditional urinal is flushed, you might think that all the waste is transported directly down the drain. Actually, the rushing water creates a mist that contains waste and contaminates the air. Since waterless urinals don’t flush, they don’t contaminate the air.
- No touching: Traditional urinals rely on flush valves to expel the waste. These valves can have thousands of dirty hands touching them over the course of their life-cycle. Zero Flush waterless urinals have no valves so there’s no touching and no spread of germs.
- Water bills: The name is no exaggeration; a Zero Flush waterless urinal literally uses zero water to operate. With the water bill alone, a Zero Flush waterless urinal could easily pay for itself within a year if not sooner.
- Maintenance: No flush valve to fix. No blocked pipes that need unblocking. Little to clean. A Zero Flush waterless urinal is so efficient it needs next to no supervision.
- Price: With all their benefits, Zero Flush waterless urinals are in higher demand. Zero Flush have been producing urinals in larger numbers, which means the prices are lower. You can now even purchase a waterless urinal for nearly half the same price as a traditional urinal.
- Potable water supplies: Yes, the world is almost covered in water so it seems like we can use it as we please. The truth is, we only have so much potable water that we have access to. With Zero Flush waterless urinals, wasting water is unnecessary.
- Energy efficiency: Some people take it for granted that water is available in pipes all the time but it doesn’t get there by accident. It takes a great deal of energy and electricity to move water. Zero Flush waterless urinals save the environment by conserving energy.
For building owners Zero Flush waterless urinals installed by Whywait Plumbing Services are a smart choice for hygiene, budgeting and the environment.

Mould is a common problem in bathrooms in South East Queensland due to our sub-tropical climate. Like most problems prevention is vital and often very simple.

Black mould on bathroom tiles
Because your bathroom and especially the shower area are the wettest areas in your home it is not uncommon to see black mould growing in the grouting and silicon sealants. Mould loves your bathroom because it is the perfect atmosphere to create the ideal conditions for mould growth in the cracks and gaps in the tiling. Consequently black mould grows in behind and through the grout joints on the tiles. As can be seen on the photo on the right black mould loves getting in behind the silicon seal on the internal corners whether it be the wall or the floor.
The most common area to find mould is in your shower where it is nourished by your body oils, shampoo and soap residue that are left behind every time the shower is used.
Poor air circulation actively assists mould growth as the warmth and moisture created in the enclosed area of a shower offer further ideal conditions for mould growth in the dark areas of the shower around the internal corners and the shower floor drain. Poor air circulation is easily resolved by ensuring you install a good quality bathroom extraction fan above the shower that turns on automatically to remove all of the steam and water particles while you are using the shower.
If you are suffering from black mould growth in your bathroom then Whywait Plumbing recommend that you act early to remove it before permanent stains are created. To get rid of early mould growth the best solution is to use a paste of baking soda and vinegar. Simply mix one cup of water with white vinegar and water to create a smooth paste. Then apply the paste to the areas where mould is growing, gently scrubing it with an old soft tooth brush until it starts to turn white and then leave it. After half an hour rinse off all the paste using your shower spray and if any mould still is visible you will need to repeat applying the paste and scrubbing it until all of the mould has disappeared.
The paste above will work perfectly on mould that is detected and removed early but if you have a real infestation then use a 50/50 mix of water and bleach in a spray bottle. Ensure you have adequate ventilation in the bathroom before you begin lightly spraying the mould. Once again spray then leave for half an hour, rinse off and spray again until all of the mould has disappeared.
Mould behind the silicon sealant on the internal corners will require more thorough work. First use a utility knife to scrape off all of the silicon and you may need to use a blade to scrape the remnants clear off the tiles. Once all of the silicon has been removed spray the mould with the 50/50 bleach until it has all disappeared. Once the mould has gone rinse the area clean and dry it thoroughly with a hot air dryer to ensure there is no moisture trapped in the open joint. Finally reapply a good quality mould resistant silicon to the joint which is specifically designed for high moisture areas.
If mould reappears within a few weeks then you may have problems with leaking pipes or fittings that require a thorough investigation by Whywait Plumbing to ensure you are not damaging internal frames and wall linings.
Remember mould is only a sympton of a bigger problem and ignoring will not make it disappear. If in any doubt call Whywait Plumbing for advice on how to deal with mould in your bathroom.

Personally, one of life’s great pleasures is walking into Zarraffa’s Coffee at Hope Island most mornings and getting that immediate lift that the aroma of coffee gives. As a plumber, one of the more problematic issues we face is when a building has a problem with sewer gases or sewer odour. I was not surprised when I came across research that showed that the leftover coffee grounds could eliminate that offensive odour that is sewer gases.
Sewer odour is hydrogen sulphide and has a characteristic rotten egg smell which can be detected at very low levels, well below those known to cause health effects.
The sewer odour smell can cause worry, anxiety and resentment as it overwhelms the sense of smell. Repeated odour events may culminate in real symptoms such as headache, fatigue and nausea. Although these are not direct health effects, they are undesirable. It is unlikely the odour will affect your health as humans smell it at shallow levels, as hydrogen sulphide is denser than air and tends to pool on the ground or the floor, especially inside a building. In addition, any absorbed hydrogen sulphide does not accumulate in the body as it is rapidly metabolised in the liver and excreted in the urine.
The problems with sewer odour inside buildings are often related to the drainage system’s venting, which requires filters. Over the years at Whywait Plumbing, we have tried many different filter systems and non-return valves with varying degrees of success in controlling sewer odour.
New research to develop a novel, eco-friendly filter to remove toxic gases from the air has found that a material made from used coffee grounds can sop up hydrogen sulphide gas. CCNY Chemical Engineering develops and tests materials that scrub toxic gases like hydrogen sulphide from the air in industrial facilities and pollution control plants. Similar to the grains of charcoal packed into water filter cartridges, the CCNY filters use a form of charcoal called activated carbon.
The manufacturers of activated carbon producers already use materials like coal, wood, peat, fruit pits, and coconut shells to make filters. CCNY concluded that our modern coffee culture could supply an abundant source of eco-friendly organic waste. An added advantage is that coffee grounds also have a special ingredient that boosts their smell-fighting power. The stimulant that gives coffee its energy jolt, caffeine, also contains nitrogen. Nitrogen dramatically increases the carbon’s ability to clean hydrogen sulphide from the air through adsorption.
Manufacturers traditionally have treated the carbon with nitrogen-rich chemicals such as ammonia, melamine, or even urea, the primary nitrogen-containing substance in urine. All of these treatments significantly increase the cost of adsorbents. Instead, CCNY carbonised coffee grounds turn them into charcoal by activation that fills the carbon with scores of minute holes about 10-30 angstroms in diameter and roughly equivalent to 10-30 hydrogen atom widths across. These densely packed pores are blanketed with nitrogen, perfect for capturing hydrogen sulphide molecules passing through.
Trials are continuing on the filters with positive results so remember, next time you have a coffee, the grounds that made it can be developed into an environmentally sustainable green filter that can control the most nauseating odour of all – sewer odour.

Toilet paper is blocking your drains, and we know it for a fact at Whywait Plumbing. Blocked drain incidences have been increasing every year since 2005.
Whywait Plumbing has noted the upward trend of annual increases in the number of blocked drain occurrences that require clearing with high-pressure water jetting equipment since 2005, with even sharper increases since 2008.
This has generally been attributed to the advent of low-flow dual flush toilets, especially the 4.5/3 litre toilet suites.
Your house drain that connects to the sewer was designed when water flows were much more substantial than they are now. Traditionally a toilet flush was 11 litres, and this flow was supplemented by inflows from the bathroom, kitchen and laundry. Prior to legislative changes in 2007, a shower deluged you with a flow of 25 litres per minute now that is 9 litres. Taps in the remainder of the house all had substantial flow rates of 20 – 25 litres per minute, but now that is 6 litres per minute.
Consequently, it made sense that the 70% reduction in water flows was the cause of this rapid increase in blocked drains. Naturally, this made complete sense in homes and business premises that were new or had upgraded their taps and toilets. But why were we seeing an increase where no such upgrades had occurred? Over the last year, Whywait Plumbing Services, like many other plumbing companies, began noticing, when undertaking a CCTV survey of a drain, large clumps of toilet paper that had not broken down in the water.
This issue with toilet paper has now reached a point where the National Plumbing Regulators have had a NATA laboratory undertaking research on the varying degrees of toilet paper quality and its influence on flow performance down a drain. Results to date are concerning as over 20 commercially available toilet paper brands were evaluated in full performance testing. There were an excessive number of these toilet papers whose performance in the poor break down in water can potentially cause more blockages than others.
It’s interesting to note that none of the toilet paper culprits that have an increased potential to cause blockages is locally manufactured. Its even more interesting that the Federal Government has a committee investigating the dumping of commodities by China into Australia and one of these commodities is toilet paper. It is doubtful whether Coles and Woolworths are too concerned about what happens to this cheap toilet they import once it passes through their checkouts. Who knows what these toilet papers are really manufactured from?
These cheap toilet papers dominate in commercial buildings where contract cleaning companies install the cheapest toilet paper they can purchase. This has resulted in alarming increases in blockages in commercial buildings.
So next time when you pick up that packet of toilet paper that is on special in the supermarket just have a look to see where it is manufactured or you may unknowingly be purchasing a blocked drain at the same time.
