hey, can you in theory add larger pipes to a microbore system (8mm)? or will it screw it? have a pressurised 8mm system and a radiator thats too big and/or a damaged pipe. spoke to a few people some said pipe is kinked rad should work, others said rad is too big, and one said adding bigger pipes to the existing system will cause the rest of the radiators in the house to stop working properly - is this the case if so why has nobody else said this!! wish there was a slight consensus as to if this is a bad idea or not. just want a warm home.
