EVOLI
This video presents the easy way to regulate the half and full flush volumes of the outlet valve (EVOLI).
The yellow rings allows to regulate the water for total flow (yellow ring with letters) and partial flow (yellow ring with the identification "H1-2-3-4-5-6-8").
The more open the total runoff ring (down), the less amount of water will be discharged, while the more the partial runoff ring is lifted (up), the less amount of water will be discharged.
This results in a daily saving water.
