IntroductionThe Ball Valve is the device that controls the flow of water from the pool to the pump. It determines how much of the water flow is from the skimmer and how much is from the floor drain. The valve is shaped like the letter T and it is sometimes referred to as a T-valve.
Open positionThe red handle allows you to rotate the internal cylinder there are markings showing ‘open’ and ‘closed. When all the ‘open’ designations are aligned with the openings (see below), the flow of water is coming half from the skimmer and half from the floor drains and going to the pump.
*Note: Your skimmer and bottom drain hoses may be opposite of what is shown on these diagrams depending on the actual location of your pump. Check your pool to see which sides they are on.
By turning the handle you can adjust the flow or shut off either the skimmer or bottom drains. For example, you might close the drains to get more suction from the skimmer if you notice a lot of floating debris on top of the water.

If not, you might want more drawn from the floor drains to reduce the amount of vacuuming necessary.

Closed positionYou can also shut off the flow going to the pump if you need to service the pump or tank.
IMPORTANT
When needing to turn the handle more than 180°, unscrew the yellow screw and raise the handle past the stop
