ABSTRACT:
A swimming pool skimming and vacuuming system includes a passage plate for insertion in the passage interconnecting a pool filter to a pool. The passage plate has a skimmer weir positioned therein for drawing off scum from the upper surface of pool. An aperture is formed in the plate for enabling automatic vacuuming of the pool while simultaneously enabling skimmer weir action to occur. A weir basket is positioned in the skimmer well for collecting scum from the weir. A top mounting plate is secured in the skimmer well and contains a basket opening therein for enabling the top surface of the basket to be positioned in the plate. A hose opening is formed in the plate for enabling the vacuum hose to be connected thereto. A regulator valve is coupled to the pool suction pump for enabling the suction between the vacuum hose and the weir basket to be adjustably controlled.
