If your compressor has an Air Intake Filter, it should be cleaned on a weekly basis (assuming you are using the compressor about 3 days a week). When the filter starts to develop debris that is becoming harder to clean out, or you notice any tears or holes in the filter, the filter should be replaced.

Generally this is caused by two problems. Either a failed condensate trap or a failed or undersized air compressor dryer. To solve the first problem, you will need to either clean the water trap or simply replace it. The second problem is a bit trickier, as you would need to repair or replace your air dryer with something larger (unfortunately, this can be a bit pricy).

This answer depends on how often you run your compressor. If you are running your compressor occasionally, then annual service would be fine. If you are running your compressor routinely, then quarterly service may be needed.

It is likely cavitation. Cavitation means that cavities or bubbles are forming in the liquid being pumped. Symptoms of cavitation include excessive noise and vibration and loss of capacity, pressure and efficiency. Cavitation can cause damage to the pump. Solutions include changing the operational parameters or even replacing your pump with a pump better suited to the application.

No. The amount of water and the pressure (head) that a centrifugal pump produces is related to the rotational speed, impeller diameter and size of the impeller vanes.
