I have recently purchased a Caroma Soveriegn 6/3 L cistern and installed it with an old pan. I was hoping the new cistern would allow for sufficient water to completely flush the waste, however there are occasions when a second flush is required (I always need to hold the button down until the flush is complete). Anyone have any ideas how to increase the amount of water for the flush - I assume the float is at a maximum height already.
Thanks
