| How to determine GPF of existing toilet? I have a ~20 year old American Standard toilet that I suspect is not a thrifty unit.
Is it possible to identify the toilet and determine the number of GPF? I am assuming that my current throne is 3.5 GPF.
A quick back of the envelope calculation shows that it empties and refills the tank to the tune of approximately 3 gallons. This ignores any water that is discharged down the tube in the center of the tank.

Read your water meter, flush the toilet, read the meter again.
1 cubic foot = 7.48 gallons |

That is where I found what appears to be a date. (1992)
I found no other markings.
I considered using the water meter, but it reads in m3, and isn't really precise enough.

Good question, I think low usage toilets say how many gallons per flush. Ours is printed under the brand.
If your does not, and since you did a rough measurement I agree with your estimate it is probably 3.5 gallons. Time for an upgrade.
It looks like your tank is insulated. That is one of the things I wanted to do when I upgraded ours. Surprising how effective a little bit of foam insulation is in preventing condensation.

You could flush multiple times until you get a decent meter reading, then divide by the number of times you flushed.
1 cu meter = 264 gallons |

Get a gallon container.turn off the water to the tank. Flush the toilet. Refill the tank using the gallon container. do the math. |

Woudn't take into account the water that goes down the refill tube into the bowl, which may or may not continue to run for a while after the bowl is actually full, wasting water down the drain. |

Also capture the water from bowl fill tube to see how much water comes out there. |

I think I am satisfied with an estimation of 3.5 gpf being accurate enough. It matches up with the age of the toilet.

Yes, the other benefit to a Cadet 3 besides 1.6 gpf is you can also get it in the height that works best, I prefer higher seating. |

The government made 1.6Gpf toilets mandatory a couple, three years after the manufactured date stamped on yours. |

Pulled the trigger. We went for a Drake II. » www.totousa.com/ProductDetail.as···ctId=407
1.28Gpf/4.8Lpf
(stock photo) I installed it today, and was surprised at how straightforward installation was. This was my first toilet. I suppose part of the ease of installation comes down to the flange being in good condition. It pays to be lucky sometimes. The next step is to install a plug behind the toilet for the washlet seat. --
