When you are connected to city water, there is a check valve in the city water inlet that does not allow water to reverse flow back into the hose, and that is where you are building up excess pressure which is causing the T&P valve to open and leak water. If you install an expansion tank and get it pressurized correctly, it will absorb that excess pressure and probably stop the water leak.
