Do Kitchen Lever Bib Tap Upstands Develop Stress-problems? All aspects of plumbing questions and answers, help, tips and information

[CatBar]

I've been told that the Upstands of Lever-handled Kitchen Bib taps could develop stress/flexing problems with time, after the Lever handle has been operated (pushed and pulled) a great number of times?

Has anyone experienced a problem with this?

It's only Kitchen Bib taps that I'm interested in finding out more about, as opposed to bathroom or garden taps.

Would also like to know of ANY problems, ie, leaking, that Lever Bib taps might develop, in comparison with ordinary taps.

I got a reply from a Plumbing company/website mentioning this about taps being able to have 'flexi tails' or 'rigid tails'.

Would this mean anything to anyone here, and would anyone know if having a 'rigid tail' would be an advantage for a Bib tap?
