I have a bottom round style diffuser with the rubber membrane. I pulled it up last week and cleaned the top off as it was not working. Put the pump back on and still no bubbles. Took apart the air line where it meets the weighted line on the edge of the bank and found out I had water in that line and I probably do in the weighted line as I got all the water out of the land line. Is there some kind of check valve in side the diffuser that needs to be fixed and can I just blow out the line with higher air compression or do I need to take the line out of the pond and drain it ?
