Many tub/shower valves are designed to be used either as a tub only or as a tub-shower combo. You will note that the valves have inlets on the sides for the hot & cold water supply, and outlets top and bottom for directing water either to the tub or diverted to the shower head. By plugging the bottom outlet with the appropriate plug and either soldering or wrapping the threads with teflon tape, the valve directs the water to the shower head.
Yes, it can also cross through a two handled faucet. Both the hot and cold sides of the faucet must be on and the flow of water must be stopped or greatly reduced on the outlet side of the faucet. This can occur when a hose with a spray nozzle is attached to a laundry tub faucet with the faucet on and the spray nozzle off, or when a shower faucet is on but the shower spray head is off. When another cold water outlet in the system is turned on then the pressure on the cold side of the laundry tub or shower faucet in question could be lowered below the pressure on the hot side and hot water can flow into the cold water side. There are faucets which have integral check valves which prevent this from occurring. WWW.WOODBRIDGEPLUMBING.COM
