I've just installed a new sink and monobloc tap in my kitchen. The supplied braided connectors that came with the tap were not quite long enough to reach the hot and cold water pipes so I extended them using a couple of "Wickes" compression flexible tap connectors. This all works fine, but I've since noticed that some similar types of connector are marked as not safe for drinking water. The Wickes connectors do not state their suitability either way. Am I safe in assuming that in the absense of any contra indication that the connectors I have used are suitable for drinking water.
