Toilet Displacement Dams

Toilet displacement dams are devices which, unlike the volume displacement devices, reduce the amount of water available per flush by holding a small amount of water out of use.

The dams usually consist of 2 pieces of flexible plastic that are wedged into the tank on either side of the flush valve and act like dams. Water held back by the dams cannot be used and is thus saved each time the toilet is flushed. At the same time the same initial hydraulic pressure is maintained, allowing normal bowl cleansing to proceed.

Tank dams save approximately 6 gallons/toilet/day, which amounts to a water savings of greater than 18%, when compared to a conventional 3.5-gallon toilet.
