Tricky plumbing question

[lnt9000]

Research has shown that cheap and not so cheap mixer taps can spring a leak if the pressure is too great, many manufacturers have warnings on their products to fit suppressors If the water pressure exceeds a particular amount, provided you comply with their requirements they will stand by their warranty, thats not to say that they will warrant a drenched kitchen due to their mixer malfunctioning.
So it would seem that perhaps in view of the fragile nature of these mixer taps it would be wise to install stopcocks, not that it would do you any good if your not home to turn them off.
Can't find any legislation for vic, jacksin can you elaborate!
Found an Interesting article on various aspects of plumbing with copper.

I sell plumbing as well as other building products. Seems to me everybody here is right (in some way). Budget mixers generally rely on the fact that, after three years, you can't find the receipt and will have to buy a new one. On the other hand quality gear like Hansa or Grohe will (usually) last for years.

Fitting stopcocks (not a regulation here in SA) is a great idea, and reducing flow to a cheaper mixer will increase its life expectancy. I'm not a lover of ceramic disc repair kits, I refuse to sell them nowadays as too many simply don't do the job. For the record I have just moved into my new house and have a combination of mixers and ceramic washer levers.

PS asking a plumber is usually the best idea, but don't forget they have their biases too. All too many will tell you the only product is Caroma (Dorf etc) and mixers are a disaster. Familiarity often breeds narrow mindedness.

Well now I cant remember if its a regulation or a recommendation for the stopcocks, but either way its because of the maintenance aspect. I believe high water pressure can indeed lead to a shorter life expectancy. However pressure cant be regulated by closing stopcocks only flow can.
