Metalic Taste To Beer

[pb unleaded]

Hi all,
I bought an Andale brand beer tap with shank and beer line, installed it through the side of my beer fridge and everything is working fine but there is this metalic taste to the beer and the first pour was green. I cleaned the tap thoroughly, got rid of the green colour but the metalic taste in the first couple of pots is still there. I ran the bleach solution through the lines and tap, it didn't help much.
Any ideas please?

My stainless Coopers Puta makes the been in there have metalicy taste. Still got me bugered on how to get rid of this flavour.

to me the green means copper. Maybe run some acid thorough there to clean it out well, then rinse and try again

Whatever you do don't use bleach! Get some proper beer line cleaner, strip the tap and clean it out.
