When on city water, check valve in water pump is leaking back and anti-freeze valve by water pump is set to anti-freeze input instead of fresh water tank.....make sure city water connection is disconnected, put water in fresh water tank, set valve by water pump so it pull water from fresh water tank and start pump to hopefully reset check valve, open faucet in trailer. Reconnect city water and see if leak again. Hope it works.
