Diverter Valve not doing the job...

I recently replaced my Price Pfister Diverter Valve in the shower and for whatever reason it seem that 80% of the water flow is going to the showerhead and the rest comes out the faucet below. Not sure what I need to do here...I changed the seat and stem completely to entirely new parts and hopefully someone here can help me out here.
Any guidance is truly appreciated..
