HBV normally just leak coolant over the floor from the back of the block. Different heat settings will/can affect te asize of leak, as can a/c on or off.

Symptoms are constant topping up of coolant.
My Heater Bypass valve blew at the back so you couldnt see any sign's of a leak except for the constant need to top up the bottle, also worth checking the condition of all 3 hose's
