Are radiator drain-offs now mandatory?
My father is getting quotes to have his back-boiler replaced. The firm he wants to use have told him that they will have to fit drain-offs to every radiator as this is now required by regulations. Can anyone confirm that this is correct, and which regulation has changed to now require this?
