Gidday guys ,thought id put this to the brains trust,that heater pipe that comes out of the back of water pump is leaking,can i just bypass the whole heater box scenario and just block the pump,any ideas guys?

It's just a O ring,very easy to change-it is the same O ring as the heater pipe from the thermostat housing,you can't bypass it from there as it circulates around the engine aswell.
