okay what can i do about the connection not sealing well where the hose meets
the van?

also when i fill up the h2o tank, and turn the knob on the sink and don't
hear a hum from the pump or get any water, should i be doing anything else?
i have not used the sink with water from the tank before and wasn't sure if
there was a certain way to do it.
