    All gray tanks I've ever seen do not have a safety valve or overflow. They just back up into the shower pan or sink when full. If your's leaks, you have a problem some place.

    Not really. Water typically backs up into the tub or sink.
    I would guess the pipe to tank connection is leaking.

    Our grey tank has no safety, neither did our last trailer. Do you have a waste cap with the garden hose threads? If so, you can drain grey water continuously as you use it, provided you're in a place that doesn't prohibit it.
