Residential Toilet

Rebate Information

Ultra High-Efficiency Toilet (1.0 Gallons Per Flush (GPF) or Less) Rebate - Up to $100!

Our residential toilet rebate pays for up to $100 when you replace a toilet that flushes at 1.6 GPF or greater with a model which has a flush volume of 1.0 GPF or lower.

Toilets usually account for the most water used indoors in an average home. Switching out a 1.6 GPF) toilet with an ultra-high-efficiency toilet (UHET) drastically cuts your toilet water usage while still providing equal or superior flushing performance.

Rebate Requirements

Replace a toilet that uses 1.6 GPF or more with an Environmental Protection Agency (EPA) WaterSense-approved UHET that uses 1.0 GPF or less and receive a rebate up to $100.

This rebate cannot exceed the combined cost of the toilet (tank and bowl) and accessory parts if needed (wax ring, supply line, seat). Original, dated, receipts are required. See the rebate program rules and requirements on the Toilet Rebate Application (PDF) for a complete listing of rules and requirements.

  • Rebate-eligible parts include the toilet tank, bowl, seat, wax ring, and supply line only.
  • Only contracted labor is eligible for the rebate (i.e. self-performed labor is not eligible for reimbursement).
  • Toilets must be installed and rebate applications must be postmarked within 90 days of the purchase date.
  • Each residence is limited to three rebates on qualifying toilets on the property.
  • Old toilets cannot be reused. Participants agree to recycle their old toilet(s). Customers may recycle their old toilets at the Buena Vista Landfill in Watsonville for a small fee. Toilet seats and all hardware must be removed prior to drop-off.
  • The Internal Revenue Service (IRS) requires all rebate program participants receiving rebates of $600 or more in cash or check, per calendar year, to be issued an IRS Form 1099 unless exemptions apply. If you are receiving a cash or check rebate (as opposed to a credit on your water bill), please submit a completed IRS W-9 Form (PDF) with your rebate application to receive a rebate.

Toilet Performance Considerations

Due to problems that arose in the late 1990s when low-flow toilets first hit the market, there has been a lingering concern by some consumers about the performance of water-efficient toilets. To address these concerns, new independent toilet testing and labeling programs have emerged, and toilet manufacturers have improved their designs to increase performance. All 0.8 GPF and most 1.0 GPF toilets currently on the market that qualify for this rebate are Environmental Protection Agency WaterSense approved. WaterSense-approval means that the toilet has undergone rigorous testing to meet EPA WaterSense's performance and efficiency standards.

These toilets are also MaP Premium certified, which means that they are in the "highly recommended" category based on tests of their Maximum Performance. (Note: MaP is an industry-leading provider of the most current plumbing data, including a scale to independently rate toilet efficiency and flush performance). More information on MaP testing can be found on the MaP website.

If you have a Niagara Stealth toilet, there are several helpful troubleshooting videos available via the Niagara Conservation website that cover easy solutions to problems such as weak flush performance and toilet gurgling.
