AI Overview
Toilet flush valves are generally categorized into two main types:
flapper valves and flushometer valves
.
Flapper valves are the most common and rely on a rubber flapper that seals the tank outlet.
Flushometer valves, often called tower or canister valves, are less common but offer a more powerful flush.
Additionally, dual flush systems, which offer both full and partial flush options, are increasingly popular.
1.
Flapper Valves
:
Mechanism:
These valves use a rubber flapper connected to a chain or handle.
When the handle is lifted, the flapper is pulled away from the tank outlet, allowing water to flow into the bowl.
Common in:
Residential toilets, particularly older models.
Types:
Standard Flapper
:
Typically a 2-inch flapper, designed for conventional toilets.
Large Flapper
:
A 3-inch flapper, often found in newer toilets.
Considerations:
Flapper size is determined by the drain opening at the bottom of the tank.
How to check size:
If the drain opening is about the size of a baseball or orange, you need a 2-inch flapper.
If it's the size of a softball or grapefruit, you need a 3-inch flapper.
2.
Flushometer Valves
(Tower or Canister Valves):
Mechanism:
These valves typically have a tower or canister-like structure that controls the water flow.
Flush:
They offer a faster, more powerful flush compared to flapper valves.
Maintenance:
Replacing a tower-style flush valve seal is relatively easy, similar to replacing a flapper.
Common in:
Some commercial and newer residential toilets.
3.
Dual Flush Valves
:
Mechanism:
These valves allow for both a full and a partial flush, offering water-saving options.
Benefits:
They reduce water consumption by allowing users to choose a smaller flush for liquid waste.
Types:
Dual flush toilets can have a push button or lever handle-controlled drop valve system.
Common in:
Modern toilets that prioritize water conservation.

How do I know what flush valve I have?
The simplest way to determine which Fluidmaster flush valve and flapper to use is to
measure the flapper that is already on the flush valve
. To identify what size is needed measure the width of the flapper from end to end. If the flapper measures 3 inches across select a 2 inch flapper.
determining whether you have a 2' or 3' flush valve and flapper
What is the difference between a 2 and 3 flush valve?
The difference in flushing power between a 2-inch and a 3-inch flush valve can be substantial, and
the larger valve can produce a better flush with much less water
. There are some great toilets using only 1.28 gallons per flush with a 3-inch flush valve.
