When installing an unvented cylinder do most tend to use balanced cold for all cold outlets including the kitchen sink tap? So take the cold mains straight to the cylinder and the back to all cold water outlets including the kitchen sink from the tee for balanced cold on the composite valve. Or is it standard to feed the kitchen tap straight off cold mains as this is were the cold main usually enters the building then go to the cylinder and take all over supplies off balanced cold? If the kitchen tap is dual flow this wont be a problem? Thanks for any input.
