sticky pump screw

[ruth0007]

i am trying to bleed a pump it is in a nightmare position, i can just about get my hand round the pipes but the screw seems jammed
are they normally really tight and what is the best tool, tried a knife!!
also do you bleed it with the system on or off
thanks

Bleed it with system off.

A little water may come out so have a rag and dish.

It may be necessary to rotate the pump when you bleed it but the operating position should be with the shaft horizontal.
