I'm trying to replace a (rusted through) leaky radiator. I ordered and received a Stelrad K1 (single) radiator and I'm confused about fitting the 'radiator valve tails'.
The instructions just say - prepare the radiator valve tails with PTFE tape (no problem) and fit to the radiator connections - the radiator connections are sealed with some sort of plug which would take an enormous phillips screwdriver or similar. Do I need a special tool to get these out? Do they actually unscrew? I've tried a bodged tool on them but they don't move easily and I don't want to damage anything.
Help please - Alan
