1. Yes, you need a filter screen. If you run it without one, you can get debris in the pump which will get stuck in some of the one-way valves and prevent them from closing.
2. If it were my pressure washer, I'd just use it and hope the calcium deposits get flushed out. Someone else may have a better answer.
