Hello Simon. Sorry but I don't understand your request. Do you mean the pressure switch by any chance? If so you have to fit the one made for any particular machine. If you wanted to use it for a different purpose I doubt anyone failed to help you regarding the water height. Pressure systems are set up to let in a certain amount of water but the calculations are all set up according to the size of the drum, the size of the pressure chamber, the size of the pressure chamber tubing etc.
