I recently installed a new Moen model 82402. When I turn the water on it comes out of both the spout and the shower head. I contacted Moen in regards to this and they thought it might have been the gate so they sent a new spout. This did not fix the problem. Does anyone have any ideas?

Crash.. is this a two handle faucet like at this link below?
