Hi guys.
I was tasked with fitting a new fill-valve to a customer's cistern, whilst I was decorating the place.
That part went fine (no leaks from cistern) but I cannot now get a good seal on the joint from the shank of the fill-valve to the old pipework.
There was no leak there before I started but I think am going to have to change component(s) as I think the old set-up was incorrect....

elbow needs to point in right direction to meet pipe

if elbow wound right up shank of new fill-valve it points wrong way

old fill-valve shank was a little longer and elbow sat just right with it

had to put packing piece put in elbow to achieve same result

still getting a little weep from top on elbow which settles here. no leak from compression joint

- shank has 1/2 BSP (male) thread
- existing elbow has 1/2 BSP nut at top and unknown-size compression fitting at other end. It's an old property so could be Imperial. Could be metric if changes have been made over the years
- position of compression-end of elbow varies (in relation to horizontal pipe) depending on how far up or down the shank it is rotated
- shank of new fill-valve slightly shorter than old one so when elbow tightened onto shank it doesn't point in same direction
- wouldn't have this problem if bent tap-connector was used as it can stay in same position as nut is tightened onto shank
- bent tap-connectors available nowadays have 1/2 BSP nut and metric compression end (15mm pipe). assume thread on that end is metric
- cap-nut on existing pipe may have Imperial thread and not fit 'modern' connector
- if so olive will need to be removed to use cap-nut from new part
- pipe could be deformed by old olive
- then will need to fit new pipe
