How to Measure a Toilet Tank Capacity

To measure the capacity of your toilet tank, you will need:

• A ruler or measuring tape
• A pen or marker

1. Flush the toilet.
2. Wait for the tank to refill.
3. Mark the water level with a pen or marker.
4. Empty the tank and measure the distance between the mark and the bottom of the tank.

The measurement you take is the capacity of your toilet tank in gallons.

Average Toilet Tank Capacity

The average toilet tank holds between 3.5 and 6 gallons of water. However, there are many different factors that can affect the capacity of a toilet tank, including:

• The size of the toilet tank
• The type of toilet flush valve
• The water pressure in the home

Toilet tanks that are larger than average will hold more water, while toilet tanks that are smaller than average will hold less water. Toilets with gravity flush valves typically hold more water than toilets with pressure-assisted flush valves. And toilets that are located in homes with high water pressure will hold more water than toilets that are located in homes with low water pressure.
