Kicking off by partially draining down the heating system again, the pipework was quickly checked for the new towel rail – at which point it became rapidly apparent that more work was needed.
Somehow one of the concealed radiator pipes had ended up 1cm adrift from where it needed to be to line up with the towel rail’s tails.
Removing the tiles concerned and altering said pipe wasn’t really an option so suitable changes to the exposed bits of pipe were hastely made to accomodate the required variance.
Without further ado the new rad was attached to the wall, connected up to the flow/return pipes and the heating refilled & bled.
One nice warm bathroom & a heating system that now needs yet another dose of inhibitor!!
