I recently fitted a new toilet in my bathroom. One of those close-coupled ones with the flapper valves: but this isn't a discussion on how unreliable these may or may not be!
On the instructions for the float valve it said that there was a pre-fitted restrictor that could be removed if the water pressure was too low. However, after plumbing in the toilet, to the mains, I find that the 6-litre cistern fills in ooooh, about 5, maybe 10 seconds. Had a look in the packaging and found a nice little corkscrew thing... seems the restrictor WASN'T pre-fitted!
I love having the cistern fill so quickly. It is great for those 2-flush situations. However, I am aware that there are two risks:
1) Will the valve survive?
2) The capacity of the overflow.
So, can a float-valve take the unrestricted pressure of mains cold?
I have temporarily remedied the situation by turning down the valve on the supply to the toilet.
