Flushing – Aqua Piston Technology

The Kohler Cimarron uses single flush gravity along with a specifically engineered bowl and trapway which work together to create a very strong siphon.

This gives the toilet a very powerful flush and along with the Aqua Piston canister the water can flow into the bowl from all angles (360 degrees).

The Aqua Piston has a durable canister which promotes a leak free performance as it is 90% less exposed.

It also works to resist any warping and deterioration of the toilet. Each flush is 1.28 gallons making this a low water consumption toilet.
