I have a problem with a new reproduction Victorian style high level cistern installed above a bog, the bog and cistern are called a 'Savoy' if that helps. Problem is when I flush the cistern the head of water is so great that a few splashes get outside on to the floor. The problem is minimised if the seat is down, but knowing the inbuilt ability of the male species to leave the seat up always - this is likely to be a problem. The cistern is a 6 litre max flush, I have tried reducing the amount of water in the tank to 4 litre via the Torbeck inlet valve but this doesn't help much. I also can`t see an adjustment setting on the flush valve to slow down the rate of water outlet to the bog once the chain is pulled. The only solution I can think of is to reduce the height of the cistern, but this would involve a lot of work & the cistern is meant to be at this height anyway. Has anyone had this problem before & if so how did they solve it ?
TIA Steve
