Mono basin tap requires check valves or not?

[Inverness]

Open vented hot water and mains pressure cold water. When mixed temperature Could the cold water override the hot causing a poor temperature of the hot. can someone put me right. Thank you.

It depends on the tap tbh, but yes you should always fit a nrv on the hot , or i do lol

+1 or half the time they come with a decent tap combo(iso and scv)
