Why the Model Number of Your Toilet is Important 

  • Accurate Repairs and Replacements: Toilets come in various designs, and not all toilets can use universal parts and parts are not always interchangeable between brands. Knowing your model number ensures you get the correct tanks parts for repairs or replacements. 
  • Accounting for Model Changes: Even popular toilets, like the Toto Drake, can have slight revisions over the years. Your specific model number is necessary to ensure you get the exact, correct repair parts that fit your toilet's current configuration. 
  • Efficient Troubleshooting: When contacting customer service or a plumber, having the model number can help them diagnose issues more quickly and accurately. 
  • Warranty Claims: If your toilet is under warranty, the model number is essential for any claims. 
  • Proper Maintenance: Different models may require specific cleaning agents or maintenance routines. Knowing your model helps you follow the manufacturer's recommendations. 

Simple Steps to Find the Model Number 

Finding the model number of your toilet is usually straightforward. On some older models it can be tricky. 

Check Inside the Toilet Tank Lid: Lift the lid off the toilet tank. The model number is often stamped or printed on the inside of the tank, either on the back wall, side wall of the tank or the lid itself. 

Look for a Manufacturer Stamp: Some toilets have a label or sticker with the model number on the underside of the tank lid or on the tank itself. 

Check the Bowl: Occasionally, the model number can be found on the bowl, near the base or on the side. If you have an exposed trap way it could be in this area near the base. 

Toilet Model Lookup on Manufacturer's Website: If you can't find the model number on the toilet, check the manufacturer's website. They often have resources to help you identify your model based on the toilet's design and features. 

You Know Your Toilet's Model Number. Now What?

Once you have your toilet's model number, you can perform several maintenance tasks more effectively: 

Toilet Parts Replacement: Order the correct replacement parts, such as flappers, fill valves, or flush handles, to keep your toilet functioning smoothly. 

Clean Properly: Use the recommended cleaning agents and methods to avoid damaging your toilet. Some models may have specific instructions to prevent wear and tear. 

Upgrade Components: If your toilet is older, you might find compatible upgrades, such as more efficient flush mechanisms, that can save water and improve performance. 

When to Call in an Expert

While many toilet issues can be handled by a handy homeowner, there are times when it's best to call in a professional: 

Persistent Leaks: If you've replaced parts and the toilet still leaks, a plumber can diagnose and fix the underlying issue. 

Complex Repairs: Issues like cracks in the tank or bowl, or problems with the toilet's base, often require professional expertise or replacement. 

Installation of New Toilets: If you're replacing your toilet entirely, a professional can ensure it is installed correctly and safely. 

Universal Toilet Replacement Parts 

Here is a quick list of universal parts that work with most toilets. 

  • 2” Universal Flappers: 

Both are great options for toilet from American Standard, Kohler, Gerber, and many other brands. 

  • 3” Universal Flappers: 

This is a solid choice for American Standard, Aquasource, Crane, Eljer, Ferguson, Gerber, Glacier Bay, Jacuzzi, Kohler, Mansfield, Pegasus, Project Source, Tuscany 

  • Fill Valves 

The Fluidmaster PRO45 has been my go to recommendation for a replacement fill valve for over a decade now. It fits a majority of toilets on the market that have a standard tank like American Standard, Kohler, Gerber, Crane, Eljer, Glacier Bay and many other brands. 

For toilets that have a smaller tank or a slim tank, even a trip lever that is at a goofy angle, the Korky 528PRO is a good option to have on hand. 

The Fluidmaster 400A contractor pack is nice if you have a few toilets in the house all around the same age. If one toilet has a fill valve that fails it is only a matter of time till the other ones could give you problems. 

Pro Tip: It is best practice to replace the supply line for the toilet if you are replacing the fill valve. They come in all kinds of different materials and finishes, we usually recommend the stainless braided closet supply line in either 12 inch or 20 inch long depending on how the water line and the toilet tank are oriented.  

  • 2” Universal Flush Valves 

Fluidmaster includes all the extras with this kit. The tank to bowl bolts, the tank to bowl gasket, and a flapper. Good choice for older American Standard Gerber, Eljer, Glacier Bay and many more. The big thing to mention is this only includes 2 tank to bowl bolts. 

Korky has all the bell and whistles in their kit as well, the big difference is we get 3 tank to bowl bolts in this kit. This will work with Kohler, Crane, American Standard, Glacier Bay, project source and many more. 

  • 3” Universal Flush Valves 

Adjustable 3 inch flush valve and 3 tank to bowl gasket, specific toilet models made since the year 2000, Kohler, Crane, American Standard, Glacier Bay, project source and many more. 

  • Universal Trip Levers 
  • The Korky StrongARM adjusts to fit all tank positions: front, angled, right and side mount toilet tanks. It comes in several different finishes:
