A faucet diverter assembly for dampening a pressure spike includes a body and a diverter bonnet assembled into the body defining a flow passageway therebetween. A diverter portion is assembled into the diverter bonnet and is axially movable by the use of an extender. The diverter portion includes and upper stem and a lower stem attached to the upper stem. Assembled onto the lower stem is a movable plunger that is spring biased by a spring positioned between the plunger and the upper stem. A return spring, received by the upper stem, acts between the upper stem and the diverter bonnet. When a pressure spike is encountered, the pressure force is sensed by the plunger by way of a flow inlet passage and movement of the plunger, in response to the pressure force, compresses the plunger spring, thereby functioning as a shock absorber.
