how much water does a toilet tank hold

One day I flushed the toilet after using it but suddenly the question arose in my mind “How much water does a toilet tank hold? To be honest, I never thought about it as it was a routine activity for me. I am sure you haven’t asked yourself the question too. I researched the water holding capacity of the toilet. Here are my findings!

How Much Water Does A Toilet Tank Hold?

The water holding capacity of a toilet tank mainly depends on the type and model of your toilet. 

Traditional gravity flush toilets hold around 6 to 7 gallons (22 to 26 liters) of water per flush. 

Modern water efficient toilets are designed to conserve water. These toilets hold around 1.6 to 1.28 gallons (6 to 4.8 liters) of water per flush to reduce water consumption. 

Ultra-high-efficiency toilets can hold as little as 0.8 gallons (3 liters) of water per flush. 

How Much Water Does A Toilet Use Per Day?

Gravity flush toilets use around 3 to 7 gallons (11 to 26 liters) of water per flush. Considering an average of 4 to 6 flushes per day, this amounts to a daily water usage of approximately 12 to 42 gallons (45 to 159 liters) per person.

Modern water efficient toilets (dual-flush or low-flow toilets) use around 0.8 to 1.6 gallons (3 to 6 liters) of water per flush.

With the same average flush frequency, water usage can be reduced up to 3.2 to 9.6 gallons (12 to 36 liters) per day.

How Much Water Does A Toilet Use Per Year?

·   Average flushes per day = 4 to 6

·   Number of days in a year = 365

If you are using a gravity flush toilet, here is how much water you use per year.

 ·   Water usage per flush for gravity flushing toilets = 3 to 7 gallons (11 to 26 liters)

·   Minimum water usage per year= 3 gallons/flush x 4 flushes/day x 365 days = 4,380 gallons

·   Maximum water usage per year= 7 gallons/flush x 6 flushes/day x 365 days = 25,550 gallons

If you have water efficient toilets, the following is the per year water consumption of your toilet.

·   Water usage per flush for water efficient toilets = 0.8 to 1.6 gallons (3 to 6 liters)

·   Minimum water usage per year= 0.8 gallons/flush x 4 flushes/day x 365 days = 1,460 gallons

·   Maximum water usage per year= 1.6 gallons/flush x 6 flushes/day x 365 days = 5,840 gallons
