How do I order a Caroma toilet?
Caroma toilets are available from distributors throughout North America. To find your closest supplier, visit the Where to Buy pages.
What is a washdown toilet?
North American toilets most commonly utilize siphon jet technology. Most of the water in the tank is used to create a vacuum or siphon effect in the trapway of the toilet bowl, which then pulls the waste out after the water. In the past, several North American toilets have been subject to clogging due to the lower volumes of water used in ultra low flow toilets. The trapways of the bowls had to be reduced to allow the vacuum to be created.
Washdown toilets do not use this flushing mechanism. When flushed, the water is released very quickly from the tank and into the bowl through an open rim bowl design. The water very effectively and efficiently pushes the waste out of the bowl, which is then followed by the water. The flush is fast and allows for superior movement down the sewage drains, as the water is following the waste. Because washdown toilets do not rely on creating a siphon effect in the trapway, the size of the trapway does not have to be reduced. Caroma toilets feature a massive 4 inch trapway, virtually eliminating the possibility of clogging!

How much water would my family of four save using a Caroma high efficiency toilet?
This depends on the volume of water your current toilets are using, but if your family currently has a 3.5 gallon (13 liter) toilet, you would use approximately 26,000 gallons (96,900 liters) of water per year for the toilet. By converting to a Caroma dual flush 1.6 gallon/0.8 gallon (6/3 liter) toilet, your family would use about 7,000 gallons (26,280 liters) of water per year for flushing toilets. That is a savings of more than 18,300 gallons (68,000 liters) of water per year!
What is an HET?
HET stands for High Efficiency Toilet, a standard that is quickly replacing the old ULF (Ultra Low Flow - referring to toilets that flush on 1.6 gallons (6 liters) of water). The old ULF standard was established in North America in the 1980s when U.S. government mandated that manufacturers could use no more than 1.6 gallons (6 liters) per flush.
An HET is any toilet that uses at least 20% less water than a standard 1.6 gallon (6 liter) toilet. In other words, any toilet that flushes on 1.28 gallons per flush or less is considered to be an HET. Many regions and cities are starting to offer rebates for HETs based on their superior water saving ability and high performance standards. All Caroma dual flush toilets are approved HETs.
What is the difference between a 270 and 305 bowl?
Caroma has 270 and 305 bowls. 270 bowls have a fully concealed trapway and fit rough-ins of 10" to 12" using the offset connector that is included. The 305 bowls have a partially concealed trapway and fit a 12" rough-in. Installation of both bowl types is quick and easy and does not require special equipment. Installation videos are available for both the 270 and 305 bowls.
Caroma toilets look good, but I am nervous about buying new technology. How do I know that they will really work?
This would be an understandable concern if dual flush technology was new, but it has been around for many years. Caroma pioneered dual flush technology in the early 1980s, and dual flush is predominantly used in most countries around the world. Caroma originates from Australia, and dual flush has been mandated in Australia and New Zealand since 1992. Caroma is the definitive leader in the worldwide dual flush market. It isn't something that they dabble in. They don't produce a few dual flush products among a sea of single flush products. It's all they do! Literally millions of dual flush toilets have been installed and are performing perfectly in homes and commercial buildings all around the world. This is a proven technology. While it is relatively new to North America, it is far from a new technology.
We live in Seattle, Washington where it rains a lot. Why should we care about saving water?
Water conservation is extremely important, even in areas of the world that experience considerable rain. Here are some reasons why:
- The true 'cost' of water involves much more than the actual amount of water an area has! Even if water is abundant (although seldom seen now), these same cities are facing increasingly severe drought conditions throughout the summer. Every drop of water entering your home must be chemically treated. The more water we use, the higher the cost of water filtration and treatment.
- Every drop of water leaving your home must be processed through a waste water management facility. This is an expensive process both economically and environmentally. The less water we use for household purposes, the less dirty water is processed and returned to our oceans.
- Population bases of cities are growing quickly. The more we can reduce our water usage, the more people can be serviced by the existing water infrastructure. Water infrastructure improvements are vastly expensive and completely funded by your tax dollars.
What is the warranty on Caroma products?
Caroma products are covered by a 2 warranty. Read Caroma's Guarantee of Product document. Please note: If warranty assistance for Internet purchases is needed, please contact the internet retailer from where the product was purchased. Only Internet purchases through on-line companies, who utilize approved and insurable shipping methods, such as foam packaging, air bags or other approved methods will be covered by the Caroma warranty. All warranty issues for products purchased through internet retailers must be initiated with the place of purchase.
What is the ADA button kit?
The ADA button kit is an optional button that is intended to be used in applications, whether commercial or residential, deemed to be used by physically challenged individuals. The ADA button kit is a raised button that makes anyone able to easily activate either of the Caroma dual flush buttons. The ADA button kit is part number 405067.
I need a spare part for my toilet, but I'm not sure which one to order. How can I find what I need?
Determine the model of your Caroma tank, for example, Bondi, Caravelle one piece, Sydney Smart, etc. Then review the spare parts list to determine the required part. Contact the company where you purchased your toilet to obtain the part you need.
Is there an anti-vandal kit for Caroma toilets?
Yes. Caroma toilets are in thousands of commercial buildings around the world and have all of the accessories required for those installations. Review the spare parts list to determine the correct part number for your toilet.
Will the Tasman tank fit onto the Caravelle 270 bowl?
The Tasman 270 is a standalone toilet. While the Tasman 270 bowl (609169) looks very similar to the standard 270 bowl (609159), the bolt holes will not align. The Tasman 270 bowl will only accommodate the Tasman polypropylene tank (model 800032). If you have a concern about a Tasman tank not fitting on to a 270 bowl, please ensure that the correct bowl was shipped.
Will the Caravelle tank fit onto the 270 or the 305 bowl?
The Caravelle tank (629435) as well as the Reflections tank (629530) or the Royale tank (624530) will fit any of the following bowls:
609159 - 270 Round Front Plus bowl
609100 - 270 Elongated bowl
609177 - 270 ADA 17" Easy Height Round Front Plus bowl
609120 - 270 ADA 17" Easy Height Elongated bowl
609151 - 305 Round Front Plus bowl
609130 - 305 Elongated bowl
Can I use any North American seat on a Caroma toilet bowl?
Yes - a Caroma 270 or 305 bowl will accommodate a standard North American round front seat and the new Caroma 270 and 305 elongated bowls will accommodate North American elongated seats. However, a lot of engineering has gone into the design of Caroma toilets, including that of the seat. Caroma seats are not only high quality, extremely attractive seats, but they are designed to 'position' people properly over the water spot in the bowl to ensure optimal cleanliness. Caroma includes some extremely popular features such as the 'quick release' seat offered on the Caravelle 2000 seat. With the push of a button, these seats quickly pop off, allowing easier and more effective cleaning. Caroma seats also finish off the look of a Caroma toilet, with shapes that completely compliment the size and design of the bowls. The color of a Caroma seat will perfectly match the color of a Caroma toilet suite. So, while the answer is yes, we would recommend the use of Caroma seats on Caroma bowls.

My Caroma dual flush toilet doesn't seem to be clearing the waste from the bowl as it should. What is wrong?
Caroma dual flush products are highly effective, washdown toilets that can be relied upon to clear waste every time. If you are experiencing difficulties, the most common problem is that the water level in the tank has not been set properly. While it is always important for water levels in toilets to be adjusted properly, it is absolutely crucial with an HET because they are working on low volumes of water. The technology is very precise, and if the water level isn't correct, this has serious impact on the flushing characteristics of the product.
How do I adjust the water level on a Caravelle tank?
This is very easy to do but more difficult to explain. Please visit our "How to and video tutorials" section for a complete demonstration of the process.
Is it difficult to install a Caroma toilet? It looks different.
No! It is no more difficult to install a Caroma toilet than any other standard North American toilet. For a complete demonstration, visit the "How to and video tutorials" section of our web site.
