$100 Multi-Family High Efficiency Toilet Retrofit Rebate

If Replacing a Toilet Manufactured in 1993 or Earlier

If your toilets are older (from 1993 and earlier), you are eligible for the $100 rebate option when you install any WaterSense certified toilet using 1.28 gallons per flush or less.

Please confirm you have all of the following

Owners of apartments buildings and multi-family properties can save water — and money — by replacing old toilets with high efficiency toilets.

Prior to 1994, the plumbing code allowed the production of toilets that used over 3.5 gallons of water per flush (GPF), but models manufactured by today’s code use much less. You can conserve water by replacing older high-volume toilets with WaterSense certified models that use 1.28 GPF or less. This could lead to a decrease in your water bill, plus you can start saving instantly with a rebate of up to $100.

What are the benefits?

Toilets can account for 30% of indoor water use, and old, leaky toilets can account for much more! Replacing old toilets with WaterSense certified toilets that use 0.8 – 1.28 gallons per flush can add up to major water and financial savings for property owners.

  • The rebate helps to cover some of the upfront costs.
  • Reduced water usage can lower your water and sewer bill month after month.
  • Products that earn the WaterSense label are independently certified to ensure they meet water efficiency and quality performance standards.
