Guys, i have no idea what to fit between wall nut and radiator valve. I need to extend it without digging wall. I bought those valves at UK but i am from different EU country, that is why i cant find localy anything that is UK standard..
i have found many things online that can possible fit, but i need some expert who tell me what exactly i need to buy, so i can do it and give it to local plumber to install it..
