As others have said it’s the law, plus at times of high demand a tank full of water can keep up and then fill up when the demand drops say during the nightOut of interest why do you both have mains water going to a tank to then be pumped to where it's needed? Do you have a lack of mains pressure? Because you're just adding something else that's got a running cost and will go wrong at some point. Or is it to do with water byelaws where you are?
