Q. "How can I find the model number and color of my Toto toilet?"

A. Look inside your tank. Always exercise caution when removing the tank lid, as it is fragile and can be easily broken if stepped on or dropped. Inside your tank on the back wall of the tank or sometimes on the right hand wall (opposite the trip lever), you will see a model number stamped or engraved in the porcelain. Typically, for Toto toilets, you will see letters with a three-digit number. There may be more letters following, depending on additional features available on that model of the toilet. Elsewhere in your toilet tank, you will find a color code. Color codes start with a # followed by a two-digit number. The most common Toto colors are #01 - Cotton White, #03 - Bone, #04 - Gray, #11 - Colonial White, #12 - Sedona Beige, and #51 - Ebony.

Q. "What's the difference between the original and 'Eco' versions of Toto toilets? Will the same parts work for both versions?"

A. "Eco" versions of Toto toilets have the same model number as the original version, but will have an "E" somewhere after the number. The only difference between the original and "Eco" versions is the amount of water they flush (1.6gpf vs 1.28gpf) - thus, they use a different flush valve and/or a different flapper that utilizes less water. The other internal components will typically be the same. Any internal differences will be noted on the product page.

Additionally, be aware that on occasion Toto has changed the NAME of certain lines, but the model number remains the same. For example, the Gwyneth one-piece is now the Ultramax II and the Gwyneth two-piece is now the Drake II. We have provided the most current names to better assist our customers, but please refer primarily to model NUMBER when selecting your toilet parts to ensure you're getting the right parts for your model.

Q. "How do the different Toto flushing systems work? Can I put parts from a different flushing system in my Toto toilet to change the gpf rate?"

A. Almost all of the Toto toilets (with the exception of a few older models that work like most other gravity-fed toilets), feature an extra wide 3" flush outlet and a larger trapway to deliver more water at a faster rate for a more powerful flush. We do NOT recommend attempting to put a different flushing system in your existing Toto toilet - toilets are designed holistically, meaning that the entire bowl, tank, internal parts, etc. are all designed to fit together in a very specific way. Even though some toilets might have similar parts and use similar technology, each toilet will perform differently based on additional factors like tank size, whether or not the porcelain has the Sanagloss finish, etc.

• Power Gravity: One of Toto's older flushing systems, this system was designed to provide maximum flush efficiency in low-profile toilets. Because of the smaller tank size, there is less water in the tank to "push" waste out of the toilet when flushing, but this is still one of the most powerful and efficient flushing systems for low-profile toilets.
• G-Max & E-Max: As mentioned above, the big difference between the G-Max and E-Max flushing systems is the amount of water used per flush. As the industry moves toward all toilets being 1.28gpf, the E-Max is essentially a "retro-fit" of the G-Max design. Like most standard toilet bowls, the water rinses straight down when you flush - so you still get a powerful flush and rinse.
• Cyclone: A Cyclone flushing system uses a single nozzle located at the tank end of the bowl just under the lip of the bowl which has no rim holes. When the toilet is flushed, water streams out of the nozzle towards the front of the bowl causing the water to swirl around the complete inside of the bowl. This Cyclone rinsing action not only completely cleans the bowl but effectively helps flush the bowl. The Cyclone efficiently out-performs other gravity flushing toilets.
• Double Cyclone: The Double Cyclone is considered by many as the "best" Toto flushing system. It provides the same powerful flush as the Power Gravity, the G-Max/E-Max and the Cyclone systems, only better! Instead of one bowl entry nozzle the Double Cyclone has two opposite side rinse inlets flowing the same direction creating more swirling force than a single rinse inlet. Basically, the water quickly swirls around the bowl when you flush, causing a wash down effect that leaves the bowl cleaner - while still using only 1.28gpf.
• Dual Max: This is Toto's first dual flush system - delivering only 0.9 gallons per half-flush and 1.6 gallons per full flush, without sacrificing the performance you expect from Toto toilets.
• Tornado: The Tornado flush uses gravity and two powerful nozzles to create a centrifugal, cyclonic action reducing waste build-up. Water is forced to spin around the rim and bowl creating a more powerful flush. The two nozzles replace rim holes to maximize the bowl and rim cleaning action with less trapped dirt. This high efficiency dual nozzle water propulsion system is used for 1 gallon or 1.28 gallon per flush toilets. The Tornado flushing system is considered to be more effective in one flush than most toilets are with multiple flushes.
• Dynamax Tornado: The Dynamax Tornado flush sends 100% of the water through the rim of the bowl so all of the water gets used to clean the bowl and remove the waste using less water more efficiently. When the toilet is flushed the Dynamax system creates a vortex using a pushing force to discharge the waste first. The powerful bowl wash combined with the waste discharge dramitically improves the amount flushed out and away. This new discharge design make for a quieter and more powerful bowl evacuation.

Q. "Toto uses many different letters before and after their numbers stamped on the inside back of the toilet tank. Are these letters just part of the number or do they have some significance?"

A. The letters shown with the part numbers are part of the Toto number and they are very significant. Each letter or combination of letters are different codes used by Toto to completely and accurately designate what the toilet or tank consisted of when it was sold. The letters MS listed before model numbers means the toilet includes a seat. The following is a list of letters Toto uses and what they mean: B=Bolt down tank lid; C=Cyclone or Tornado flush; CST=Gravity type toilet; CT=Bowl; D=Insulated tank; E=E-max 1.28 gpf; F=Universal bowl height 16.125"; G= Sanigloss or CeFiONtect™ (ceramic glaze); L=ADA height 16.5" high bowl; M=Dual-Max; R=Right hand tank lever; S=G-Max; ST=Tank; T=Drain valve tower type; U=Ultra low volume (1.0 gallon).

Example: CST604CUFG: CST=Gravity type toilet; 604=Ultramax II tank model number; C=Tornado flush; U=Ultra low volume (1.0 gallon); F=Universal height; G=CeFiONtect (ceramic glaze);
