A pool jet fitting can include an insert housing defining an insert body, a housing channel, and a base disposed within the housing channel. The base can include an outer sidewall that defines an internal chamber. The fitting has a valve disposed within the internal chamber. The valve includes a valve body, a valve channel that extends into the valve body along the first direction, and a valve opening that extends through the valve body and into the valve channel along a second direction that is angularly offset with respect to the first direction. The valve is movable between a first position whereby the valve opening has a first area through which the water flow moves and a second position whereby the valve opening has a second area through which the water flow moves that is greater than the first area.
