Narrative:

Received this aircraft in ZZZ; where the local maintenance told me the #3 bleed hp valve had to be secured shut because the wire going to the switch that operates it was faulty. In cruise from ZZZ to ZZZ1; we got a bleed 3 advisory message; ran the appropriate QRH procedure and landed without incident. Upon arrival to ZZZ1; we wrote it up and figured it was associated with the hp valve. The message was cleared and eventually we left for ZZZ2. During climb out; once again the message reappeared; and this time when we ran the procedure it was determined we would not have anti-ice on the #3 engine. We had not yet coasted out; so I contacted dispatch and maintenance via satcom so we could figure out what the best course of action would be. After an extensive discussion; weather analysis and input from captain. It was determined we would be ok to continue to ZZZ2. This was a very time; resource and energy consuming situation which in my view could have been easily handled if we had just nipped it in the bud. This aircraft was being routed ZZZ-ZZZ1-ZZZ2-ZZZ3-ZZZ4; where in ZZZ4 it is going in for a C check. I feel there was the feeling of just pushing it to get it to ZZZ4 where the issues would be resolved at the check. In the end; the aircraft ended up being delayed in ZZZ2 for this and other issues which came to light during our flight to ZZZ2.
