Re: How to determine GPF of existing toilet?
said by PoloDude:Also capture the water from bowl fill tube to see how much water comes out there.
Get a gallon container.turn off the water to the tank. Flush the toilet. Refill the tank using the gallon container. do the math.
Divert the refill tube into another container and measure the amount of diverted water.
