High level cistern flush too powerful
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 |

If the problem is flow rate rather than the amount of head, as such, maybe you could cobble together some sort of flow restricter in the flush pipe? Maybe a rubber disc with holes or a piece of mesh?

Has anyone had this problem before & if so how did they solve it ? TIA Steve The easiest solution is to reduce the flow rate through the flush pipe. Disconnect it either at the pan or the cistern end and insert a suitable reducer. Something made from a waste pipe blanking plug that will fit inside the pipe ought to do it. Experiment a little first to get the flow rate right, then you can fit it in place with silicone sealant. You hould be able to maintain the standard flush volume, but reducing the rate will stop splashing, but just make the flush last a bit longer. ..andy To email, substitute .nospam with .gl |
