You don’t know my point, my post was in response to post 16, water exists on the planet and will stay constant in that way, but that has nothing to do with water regionally, or nationally, or locally, or much of anything else, or in the design of mechanical devices that use water.
By the way I suppose everyone supports the government getting involved in the design of ballcocks, that is something related to toilets that I definitely wanted government to involve itself in and they did.
