Issue fitting Worcester fitting loop

[michaelallen315]

I have a Worcester Bosch Junior 24i boiler and am adding a fitting loop. An issue I am having is the that I am unable to turn the blanking plugs. Is there anything that could be causing this?

Are you supposed to turn those? What filling loop are you adding?

They just unscrew.

All I can think of is some deposit on the thread. Some white crud is visible in the pic.

I assume the system is drained?
How has it been filled up to now?
If it's a new job (but doesn't look like it with the white stuff) I'd have thought the installer would have taken care of it.

Decent sized flat blade screwdriver or a socket ,never had a issue getting them out.

Looks like it has a hexagon. Box or socket spanner might do it.

It depends how long the plugs have been in...if years then forget it...they have seized in there. Been there, tried and failed.
