On question 4060 the Rov mentioned that one has to avoid drinking water during the beginning of the Tekufa only for one hour. Yet, I’m aware that for those who keep that tradition, the prohibition stays on even after. What is correct?

Poskim mention that for those who keep the tradition of not drinking water during the hour of the beginning of the Tekufa, as mentioned above, once the water collected then, it maintains its restrictions even after that time and when used or mixed with other edibles, the ones that keep this tradition should abstain from consuming them.
