I am in the process of installing a new bathroom. As Bath toilet etc

my newly acquired pipe bender, having completed a few bends with no

sds sdrill). At random during bending the tube started kinking
(15mm). There appears to be no pattern to this, i have tried
going slow, fast etc. Most bends are at 90o. 1 particular tubes
seems to be more susceptible than others.

Anybody any ideas as to what i am doing wrong.


Could be cheap copper. Make sure the bender is clean, give both parts
a good rub with wire wool.

Some grades of copper pipe are not designed to be bent
BS specs refer to table X and table Y pipes. One bends Ok the other does
not. Unhelpfully I can't remember which is which but I did try bend the
wrong sort once and had the problems you describe.

Thanks for all your replies.

Have tried the wd40 trick just as a test but to no avail. How can
i tell if the tube is table x or y? I bought it from the local
William Wilson, which is always pretty busy, so i doubt if it would
be lying around for all that long.

Thanks for all your help
