skimmer

You filled the skimmer with water first??? Did you prime it properly with pinching the air intake hose off till it straightens out, the valve should be adjusted until the bubble line is around the neck. .

there are 2 separate hose connections, one to prime and once primed I move it to the other. Did that and had to watch as adjustment seemed to take a coupl of hours flow is good now just loud.
