tap tails too soft for compression?

[ColJack]

I had to trim the one tail down so I could go to the left and they wouldn't clash with each other.
the cutter squished the pipe a bit when I tightened the finger screw so it's really soft copper..

now for the back story.....

I fitted my kitchen sink this weekend and got away with not much more than a dribble on the kitchen floor when a hot pipe from the bathroom gurgled after being empty for 20 mins..

all went well with only a minor spray where i forgot to tighten one nut on an elbow..

besides that, no sign of leaks

until today..
running a cable for my dishwasher i noticed that the nuts to the copper tails that came with the tap seemed to be weaping a tiny bit..
there's water round the top of the nut and a single solitary drip that was waiting to fall.. ( after watching it for 5 mins, it didn't so it's a very slow weap.. )

I tightened them as much as i dare when I put them in.

so is it time for some boss white or whatever you use these days?

so you probably squashed the olives in to the copper pipe by over tightening.

no.. finger tight and a half turn with the wrench.. as I've seen recomended on here before..

Exactly - then a tweak if necessary, sufficient to do the job.

Or a smear of boss white or similar.....'potable water' type on the cold water.

Have they changed the labelling to "wholesome" yet? - haven't bothered to look.

CJ - if still no joy, you could always solder a short stump of ordinary copper onto the tail and compress onto this.

Or (I await the usual derision) - replace with a couple of flexis
