I need to resite a radiator upstairs, is it ok to quickly push on an 8mm speedfit in line isolator to avoid draining down the system and is it good practice to use this type of fitting in the central heating system
I am fitting a new bathroom suite which is fairly simple but I am struggling to decide how to connect the 4" waste from the loo to the existing lead pipe protruding from wall is there some type of flange or coupling available
