okay first things first, there is a white valve near the bottom of my hot water tank. it has one white knob and a black knob. the white knob–when turned–drips small amounts of water on the ground. the black knob does nothing when turned. however, the white valve has been leaking for about 1 week now and its covering my floor with water, and it will not stop leaking. i don’t know what the problem is–its not the T&P valve–can anyone help? thanks
