K-3981-4737 Technologies and Benefits:

  • Single-flush gravity uses the force of gravity and a precision-engineered tank, bowl, and trapway to create a strong siphon during flushing
  • AquaPiston canister allows water to flow into the bowl from all sides (360 degrees), increasing the power and effectiveness of the flush
  • Flush valve's 3:2 ratio harnesses the natural force of gravity and optimizes flush performance
  • Durable canister design has 90% less exposed seal material than a 3-inch flapper, for leak-free performance
  • Light-touch canister flush requires a lower actuation force than a flapper

Installation:

  • Standard 12-inch rough-in
  • 10-inch and 14-inch rough-in kits are also available
  • Supply line not included
  • Bidet seat requires a dedicated circuit electrical outlet

Water Conservation & Rebates:

  • WaterSense toilets meet strict EPA flushing guidelines, using at least 20 percent less water than 1.6-gallon toilets
  • Eligible for consumer rebates in some municipalities
