    We're going to be filtering under reduced pressure.

    We're using running water from a tap as the suction.

    We've been told to "check there's good suction before we start"

    How do you check if it's good suction?

    It usually just flows through very quickly. Are you doing Buchner filtration?

    Hi yes we're using Buchner flasks. They kept emphasizing to check for good suction. So since they were emphasizing it so much, I guess it's important!

    Best way in my experience is to place your palm over the top of the buchner funnel to form a seal and you will be able to feel if there is a vacuum. Water will go through a filter paper fairly quickly with little/no vacuum.
