Kink/ crease in Pipe

[sheep]

I notice when i was under the floor boards that one of the radiator pipes that has been bent in position has a like a crease/kink on it. As if its been bent into position then bent back again to allign. Its a small crease sticking up about 1 mm on the bend.

Can this be a potential week point? or prone to bust pipe in winter. Or if its ok and not leaking do just leave it?

Thanks

Any bend in a pipe is a potential weak point because as you bend the pipe the outer bit stretches and consequently gets thinner, if it's under the floor dowstairs it should be lagged to prevent freezing.

lag it and leave it
