Now before you even say it, the obvious answer is that there is a crack halfway up. That may indeed be the case, but I was wondering if anything else could be the problem?

If I fill the tank full (by the gauge, not until water comes out the vent), it drips very slowly out the back of the coach. If I drain it until the 3/4 light goes out, it can sit forever and not leak a drop. The system holds pressure and the pump does not cycle.

The tank is not easily accessible to inspect (Royale rear bath). Any thoughts?
