suction valve in my Constantine spa from Sundance

Of the four (4) suction valves located in the foot well, it appears that only three of them work. I have tried all the settings available with the pumps and still only the three work. The one directly below the skimmer unit does not appear to draw.

Please advise.

    Don with the select series Constance spa that footwell suction is plumbed inline with the filter suction. You will not experience much draw from that fitting typically. If the filter gets severely soiled and or the filter suction gets severely soiled a check valve will open up and you may experience a certain amount of draw from that fitting.
