Alpha cb24 diaphram

[Plumb idiot]

dropped on floor when removing which way round does it go back in eg:
Diaphram itself long pin to left looking at boiler or short?
Large spring to the left of diaphram looking at boiler or to the right?
Desperate to sort as no boiler no water no heating.

Shouldn't your post be in the Plumbing forum?

Yep looks like my name was correct. I have found drawing now and job done.
Cheers for pointing out my error
