Toilet Rebate Application

1. Look for a Label or Stamp on the Toilet

Most modern toilets have the flush volume printed or stamped in one of the following locations:

  • On the bowl near the seat hinge (where the lid meets the tank)
  • Inside the tank (on the back wall or underside of the lid)
  • Near the base of the toilet

Look for something like: “1.6 GPF” (Gallons Per Flush); “1.28 GPF” or “WaterSense”; Older toilets might say “3.5 GPF”

2. Check the Inside of the Tank

Lift the lid off the tank and inspect:

  1. Back wall inside the tank often has a manufacturer’s stamp including GPF and date.
  2. Some models also have the gallons/flush molded into the porcelain.

3. Estimate Manually (If No Label is Found)

You can do a basic test:

  1. Turn off the water supply to the toilet (valve near the base).
  2. Flush to empty the tank.
  3. Use a bucket to refill the tank with water, measuring how many gallons it takes to reach the normal water line.

4. Search by Model Number

Find the model number (usually inside the tank or under the lid), then:

  • Search online (e.g., “[Toilet model number] GPF”)
  • Visit the manufacturer’s website

Frequently Asked Questions

Low-flow, WaterSense certified toilets use 1.28 gallons per flush which is 20% less than the current federal standard of 1.6 gallons and significantly less than older model toilets which can use up to 6 gallons per flush. EPA’s WaterSense labeled toilets can be found at local hardware stores as well as home improvement stores.

Toilets are the main source of water use in the home, and replacing a less efficient toilet with a  EPA’s WaterSense labeled toilet can save thousands of gallons of water each year. Saving water not only can save homeowners money on water bill, but also decreases demands on limited water sources.
