Abstract
A gauge for a pool filter in which the gauge includes a housing mounted on top of the filter, the housing having an interior chamber which is fluid connected at the bottom to the upper interior of the filter. The removable top of the gauge housing supports a vertical tube extending down into the chamber, the tube being open only at the lower end. A cup-shaped member is supported inside the chamber and receives the tube. The interior of the tube is visible from outside the housing for observing the level of liquid in the tube.
