Moen kitchen faucets with a side sprayer have a diverter to distribute the water to the sprayer. When the sprayer is not getting enough water pressure, the diverter requires cleaning or replacement. Sediment builds up within the diverter, causing the water pressure to drop in the sprayer. Removing a Moen kitchen faucet diverter depends on what type of faucet you own. The diverter in a two-handle faucet resembles a faucet cartridge. Single-handle faucet diverters are much smaller and attach through the front of the diverter housing.
