I just got my new tub fixed in by a plumber. He installed a new Delta valve, faucet and a shower head. When I went to test the valve to make sure it works perfectly the water came from the faucet, but it also started coming out of the shower head when the shower wasn't on. Please help me!!

Why didn't you call the plumber back? He should have tested it.

Yes I agree with Ma0641 call the plumber, Thank.
